Methamphetamine Frequently Asked Questions
deadlock@paranoia.com
April 15, 1996
Abstract
Surprisingly, there does not appear to be a comprehensive source of
information relating to methamphetamine. While no list is ever complete, this
one attempts to answer technical questions related to the chemical
methamphetamine. Unfortunately, there tends to be a great deal of street lore
that is blatantly wrong about methamphetamine and similar compounds. This
document also attempts to point out some of the more common myths, and provide
rational explanations.

information for any particular purpose. The author does not endorse the abuse of
any drugs, legal or otherwise.
This information has been gathered from openly available sources.
This is a preliminary document and should be considered fictitious until
proven otherwise.
Overview
Methamphetamine (also known as speed, meth, crystal, crank, and sometimes
confusingly called ice) is a chemical widely known for its stimulant properties
on the human body. It is frequently confused with other drugs that share similar
symptoms, including amphetamine, 4-methyl-aminorex, ephedrine, caffeine, and
other chemicals, both legal and illegal.
Terminology
In this document, we shall refer to the drugs by their common chemical names,
rather than by "street names", since the street names do not have a
one-to-one correspondence to actual chemicals. For example, the term
"speed" can mean methamphetamine or amphetamine. The term
"ice" is generally considered to apply to 4-methyl-aminorex, but is
often used to refer to relatively pure (and in some cases, not so pure) forms of
methamphetamine.
We shall use the term "methamphetamine" to refer to the substance
in either its free base (i.e. simple, unadorned) or salt (usually hydrochloride)
form. When precision is needed, we shall explicitly state one form or the other.
Pharmacology
This is one of the most difficult sections to write, partially because there is
very little "science" involved. The literature gives conflicting
reports, due to the fact that many criterion are subjective, and probably also
due to confusion over terminology.
The pharmacological effects of methamphetamine are very similar to those of
similarly structured molecules.
Administration
Methamphetamine can be taken orally, snorted, smoked or injected, in
approximately increasing order of immediacy of onset.
Onset
Onset can be immediate (in the case of injection), or can take as long as 30-40
minutes if ingested orally.
Duration
Duration is subjective, but is probably on the order of 4 - 8 hours. Delayed
absorption (for example, due to oral ingestion) can prolong the effects relative
to time of administration. Of course, larger doses last longer due to the fact
that it is removed from the blood at a finite rate.
Plasma Life
The length of time that methamphetamine will stay in the plasma (blood) is
between 4 to 6 hours. It can be detected in the urine one hour after use and up
to 48 hours after use.
Dosage
A toxic reaction (or overdose) can occur at relatively low levels, 50 milligrams
of pure drug for a non-tolerant user. Different peoples' metabolisms work at
different rates, and drug strengths vary, so there is no way of stating a
"safe" or "unsafe" level of use.
Effects
These include euphoria, hyperexcitability, extreme nervousness, accelerated
heartbeat, sweating, dizziness, restlessness, insomnia, tooth grinding,
incessant talking, and other effects.
Methamphetamine and other CNS stimulants have strong bronchodilation effects.
Vasoconstriction (tightening of blood vessels) and pupil dilation are also
common. Elevated blood pressure, heart rate, and other general symptoms of
increased sympathetic nervous activity.
The physical effects are almost assuredly due to interactions between the
amphetamine structure and human physiology, probably due to the similarity to
adrenaline (epinephrine).
Mental capacity is not diminished directly by the drug. In fact, some studies
have shown slight increases in mental capacity on simple tasks. It has been
prescribed for attention deficit disorder, among other things.
Confusing reports here tend to center around the effects of fatigue on mental
capacity.
Emotional responses may range from euphoria to anger and paranoia.
Preliminary doses tend to produce the former, while continued use (e.g. for
three or more days) tends to produce the latter.
It appears that these feelings may be linked to the neurotransmitters
dopamine and/or serotonin, although I have not seen a good reference on this
yet.

Chemistry
This is the easiest section to write, and the most fun, since I can be
relatively sure of the facts.
Molecular Information
All information is on free base unless otherwise noted.
Naming
Methamphetamine Free Base:
- Chem Abstract Service (9th+ CIP) uninverted name:
- N,alpha-Dimethylbenzeneethanamine
- Previous name:
- d-N,alpha-dimethylphenethylamine
Alternate Names:
- d-N-methylamphetamine
- d-deoxyephedrine (e.g. right-handed ephedrine, minus an oxygen)
- d-desoxyephedrine
- 1-phenyl-2-methylaminopropane
- d-phenylisopropylmethane
- methyl-beta-phenylisopropylamine
- Trademarks:

Methamphetamine Hydrochloride:
What we mean by hydrochloride is that it has formed a "salt". The
basic structure is unchanged, but an HCl molecule has become attracted to the
free base. In this case, the hydrogen from the HCl has become attracted to the
nitrogen in the free base.
You will notice that the salt form is much more common. This is for
physiological reasons. The same reaction which attracts the free base to HCl
could also attract it to other molecules, causing irritation and other symptoms.

Manufacturing methamphetamine, on the other hand, requires the use of not
just ether, but reducing agents such as LiAlH4. BAD STUFF! There
are other recipes, but none to practical to attempt. Apartment manufacture
of meth is not possible.
Reduction of ephedrine with HI is a little better than LAH reduction.
Condensation Product of Phenylacetone and Methylamine
From: ez026264@dale.ucdavis.edu (Speed Raver)
Assuming you don't have amphetamine lying around, an easy synthesis with a
very high yield is to reduce the condensation product of phenylacetone and
methylamine. The benefit of this method is that different amines can be used
to produce novel N-alkyl amphetamines (ethamphetamine, tert-butylamphetamine,
etc.)
From Ephedrine or Pseudoephedrine
From: ez026264@dale.ucdavis.edu (Speed Raver)
Making it from ephedrine or pseudoephedrine is possible. The only
difference between methamphetamine and (pseudo)ephedrine is that damn alpha-hydroxy
group. Reacting your ephedrine with thionyl chloride replaces the OH with Cl
to produce N-methyl-alpha-chloroamphetamine as an intermediate. Hydrogenating
this product is easy: use lithium aluminum hydride, sodium borohydride, or
even hydrogen gas with nickel or platinum metal as a catalyst. The product of
this step is N-methylamphetamine and HCl. Evaporate off the water and you have
methamphetamine hydrochloride.
From: yshan@bcarh697.bnr.ca (Yogi Shan)
Hydrogenation starting with (-) ephedrine, whether direct or via the
halide, will give d-meth. If you start with dl-ephedrine, you get dl-meth.
Reduction With Hydroiodic Acid and Red Phosphorus
From: lamontg@u.washington.edu (Lamont Granquist)
From Fester, Secrets of Meth Manufacturing:
Method 4: Reduction With Hydroiodic Acid and Red Phosphorus
In this procedure, the alcohol grouping of ephedrine, pseudoephedrine, or
PPA is reduced by boiling one of these compounds in a mixture of hydroiodic
acid and red phosphorus. Hydroiodic acid works as a reducing agent because its
dissociates at higher temperatures to iodine and hydrogen, which does the
reducing. The dissociation is reversible. The equilibrium is shifted in favor
of dissociation by adding red phosphorus to the mixture. The red phosphorus
reacts with the iodine to produce PI3, which then further reacts
with water to form phosphorus acid and more hydroiodic acid. Since the
hydrogen atom of the HI is being absorbed by the ephedrine, the red phosphorus
acts as a recycler.
In some reductions, the need for HI is dispensed with just by mixing red
phosphorus and iodine crystals in a water solution. The red phosphorus then
goes on to make HI by the above mentioned process. With a small amount of due
care, this is an excellent alternative to either purchasing, stealing, or
making your own pure hydroiodic acid.
This method has the advantage of being easy to do. It was formerly the most
popular method of making meth from ephedrine. Now red phosphorus is on the
California list of less restricted chemicals, so an increased level of
subterfuge is called for to obtain significant amounts. One might think that
this is easily gotten around by making your own red phosphorus, but this is a
process I would not want to undertake. Ever hear of phosphorus shells? I would
much rather face the danger of exploding champagne bottles. Those who insist
on finding out for themselves, will see Journal of the American Chemical
Society, volume 68, page 2305. As I recall, the Poor Man's James Bond also has
a formula for making red phosphorus. Those with a knack for scrounging from
industrial sources will profit from knowing that red phosphorus is used in
large quantities in the fireworks and matchmaking industries. The striking pad
on books of matches is about 50% red phosphorus.
The determined experimenter could obtain a pile of red phosphorus by
scraping off the striking pads of matchbooks with a sharp knife. A typical
composition of the striking pad is about 40% red phosphorus, along with about
30% antimony sulfide, and lesser amounts of glue, iron oxide, MnO2,
and glass powder. I don't think these contaminants will seriously interfere
with the reaction. Naturally, it is a tedious process to get large amounts of
red phosphorus by scraping the striking pads off matchbooks.
Another problem with this method is that it can produce a pretty crude
product if some simple precautions are not followed. From checking out typical
samples of street meth, it seems basic precautions are routinely ignored. I
believe that the by-products in the garbage meth are iodoephedrine, and the
previously mentioned azirine. If a careful fractional distillation is done,
these products can be removed. They can be avoided in the first place if, when
making hydroiodic acid from iodine and red phosphorus, the acid is prepared
first, and allowed to come to complete reaction for 20 minutes before adding
the ephedrine to it. This will be a hassle for some, because the obvious
procedure to follow is to use the water extract of the ephedrine pills to make
the HI in. The way around the roadblock here is to just boil off some more of
the water from the ephedrine pill extract, and make the acid mixture in fresh
pure water. Since the production of HI from iodine and red phosphorus gives
off a good deal of heat, it is wise to chill the mixture in ice, and slowly
add the iodine crystals to the red phosphorus-water mixture.
To do the reaction, a 1000 ml round bottom flask is filled with 150 grams
of ephedrine hydrochloride (or PPA-HCl). The use of the sulfate salt is
unacceptable because HI reduces the sulfate ion, so this interferes with the
reaction. Also added to the flask are 40 grams of red phosphorus and 340 ml of
47% hydroiodic acid. This same acid and red phosphorus mixture can be prepared
from adding 150 grams of iodine crystals to 150 grams of red phosphorus in 300
ml of water. This should produce the strong hydroiodic acid solution needed.
Exactly how strong the acid needs to be, I can't say . I can tell you that
experiments have shown that one molar HI is ineffective at reducing ephedrine
to meth. The 47% acid mentioned above is a little over 3.5 molar. I would
think that so long as one is over 3 molar acid, the reaction will work.
With the ingredients mixed together in the flask, a condenser is attached
to the flask, and the mixture is boiled for one day. This length of time is
needed for best yields and highest octane numbers on the product. While it is
cooking, the mixture is quite red and messy looking from the red phosphorus
floating around in it.
When one day of boiling under reflux is up, the flask is allowed to cool,
then it is diluted with an equal volume of water. Next, the red phosphorus is
filtered out. A series of doubled up coffee filters will work to get out all
the red phosphorus, but real filter paper is better. The filtered solution
should look a golden color. A red color may indicate that all the phosphorus
is not yet out. If so, it is filtered again. The filtered-out phosphorus can
be saved for use in the next batch. If filtering does not remove the red
color, there may be iodine floating around the solution. It can be removed by
adding a few dashes of sodium bisulfate or sodium thiosulfate.
The next step in processing the batch is to neutralize the acid. A strong
lye solution is mixed up and added to the batch with shaking until the batch
is strongly basic. This brings the meth out as liquid free base floating on
top of the water. The strongly basic solution is shaken vigorously to ensure
that all the meth has been converted to the free base.
With free base meth now obtained, the next step, as usual, is to form the
crystalline hydrochloride salt of meth. To do this, a few hundred mls of
toluene is added to the batch, and the meth free base extracted out as usual.
If the chemist's cooking has been careful, the color of the toluene extract
will be clear to pale yellow. If this is the case, the product is sufficiently
pure to make nice white crystals just by bubbling dry HCl gas through the
toluene extract as described in Chapter 5. If the toluene extract is darker
colored, a distillation is called for to get pure meth free base. The
procedure for that is also described in Chapter 5. The yield of pure
methamphetamine hydrochloride should be from 100 to 110 grams.
Lithium-Ammonia Reduction
Reference: Ely, R. A. and McGrath, D.C., "Lithium-Ammonia Reduction of
Ephedrine to Methamphetamine: An Unusual Clandestine Synthesis," Journal
of Forensic Sciences, JFSCA, Vol. 35, No. 3, May 1990, pp. 720-723
Procedure:
All the chemicals were reagent grade, with no special treatment of the
tetrahydrofuran (THF), and the atmosphere above the condensed ammonia was not
flushed with nitrogen gas.
A three-neck flask was cooled in a dry ice/acetone bath. A condenser was
fitted in the center neck, an additional funnel containing l-ephedrine base in
THF was fitted into one side neck, and a rubber stopper fitted with a glass
tube extending to the bottom of the flask was fitted in the third neck.
Anhydrous ammonia gas was condensed and collected in the flask. Small pieces
of lithium metal were rinsed in petroleum ether, patted dry, and added to the
condensed ammonia. A deep royal blue color was noted as the lithium metal
dissolved in the condensed ammonia.
The l-ephedrine was added drop wise to the lithium ammonia solution over a
period of approximately 10 minutes with stirring. When all of the l-ephedrine
had been added, ammonium chloride was added slowly to the solution. The flask
was removed from the cooling bath, and the condensed ammonia was allowed to
warm to room temperature and evaporate from the flask through the side necks.
When most of the ammonia had evaporated, water was added to the remaining
solution until it cleared and any remaining lithium metal was decomposed. The
remaining solution was removed from the flask to a separatory funnel, where
the aqueous layer was discarded. The THF layer was dried with magnesium
sulfate, and the hydrochloride salt of the methamphetamine was made by
bubbling hydrogen chloride through the THF.
The same procedure was used, substituting phenylproponolamine and
methylephedrine as the starting materials. A second synthesis was conducted
with l-ephedrine, using the same procedure except that the reaction was not
quenched with ammonium chloride.
Results:
The reaction was found to reduce l-ephedrine to d-methamphetamine quickly
and easily . Furthermore, it was found that the reaction converted
phenylpropanolamine to amphetamine and methylephedrine to dimethylamphetamine.
The time required for the reaction to proceed from the condensing of the
ammonia gas in the reaction flask until the excess lithium was decomposed was
approximately one hour. The majority of this time was spent waiting for the
condensed ammonia to evaporate from the reaction flask.
It was also found that the ephedrine would reduce to methamphetamine
without the addition of ammonium chloride as a quenching agent.
From: eleusis@netcom.com (Eleusis)
According to the infamous J.For.Sci. article describing a "novel
method of amphetamine production", the researchers concluded that with or
without an ammonium chloride quench yields were good. I like this article
especially because the rinky-dink DEA chemists that wrote it didn't seem to
entirely grasp the concept of the procedure they were doing (in fact, a
slightly modified Birch reduction known by some other name I can't recall).
All in all, quite an entertaining and educational article ;-).
From: dmurphy3@aol.com (DMurphy3)
This may be so (in fact I read the same article), but typically a water
quench leads to the alcohol, which is what we were trying to get rid of to
start with. Also, if one were using Na rather than Li (Na is the Birch, I too
forget the Li named reduction), adding water to quench will *definitely* be
exciting, particularly considering the flammability of THF or ether.
Apparently they were following the guys handwritten notes. It would have
been even more interesting had they used the real Birch method, using Na,
especially when they tried the water quench ;>)
From: eleusis@netcom.com (Eleusis)
Yep - apparently that would be the case. As well, any extra Li (or Na if
doing the straight Birch method) would convert to the Hydroxide, which might
fuck the product up a bit.
I bet you they *did* do that the first time, and then, after they replaced
that wing of the lab, they decided not to "publish" those results
;-).
From Phenylalanine
From: ez026264@dale.ucdavis.edu (Speed Raver)
A surprisingly simple synthesis is possible from the amino acid
phenylalanine, which is available at health food stores for about $14 for 100
tablets. Phenylalanine is 2-amino-3-phenylpropanoic acid, which is more or
less amphetamine with a COOH where the CH3 should be at the end of the chain.
Thionyl chloride will replace the OH with a Cl, which falls off and is
replaced by H when you give it lithium aluminum hydride, sodium borohydride,
or hydrogen gas and nickel/platinum. If you use hydrogen and metal for that
step, you'll ha v e to reduce the carbonyl group with one of the hydrides, so
best save time + effort and use them and do both reductions at once. When that
carbonyl is reduced, you now have amphetamine. Go back up to that first one I
mentioned for upgrading amphetamine into methamphetamine.
Incomplete Syntheses
These are methods that are subjectively evaluated to be less useful, but still
may serve as interesting lessons in applied chemistry.
Synthesis from Amphetamine
From: ez026264@dale.ucdavis.edu (Speed Raver)
One of the easiest ways to make methamphetamine is from amphetamine. Of
course, this assumes you have amphetamine in the first place, but let's just
pretend you have some and you want to spice it up a bit. The difference
between amphetamine and methamphetamine is the addition of a single methyl
group (CH3) to the amino group sticking off the middle carbon atom
in the chain. Fortunately, substituting amines is really simple. Vaporize your
amine (your amphetamine) with a bunch of vaporized chloromethane (CH3Cl,
a solvent) and some gaseous pyridine... voila, the amino group takes the
methyl from the chloromethane and lets a hydrogen go. The hydrogen joins the
liberated chlorine, and the resulting HCl is soaked up by the pyridine. The
pyridine is optional. Adding it drives the reaction a bit by pulling the
excess HCl out of the equation, but it's not necessary.
Methylamine
From: dnaugler@sfu.ca (David Naugler)
jkenner@cello.gina.calstate.edu (Jason Kennerly) writes:
Does the P2P method [reductive amination] ever end up attaching TWO chains
to the same methylamine, producing a crazy looking monster with two
"wings"
This last question is solved be reference to a principle called the law of
mass action. An excess of methylamine will inhibit the secondary reactions.
Typically, a reductive amination done in a parr bomb or using sodium
cyanoborohydride is done with a five times molar excess of methylamine (or
methylamine hydrochloride.)
Phenylacetone
From: jkenner@cello.gina.calstate.edu (Jason Kennerly)
Let me know how bromobenzene + acetone + NaOH turns out. I'm interested in
this since I haven't seen it anywhere else (unlike some people, I don't have
the Abstracts in my closet :)
Make sure to use an EXCESS of acetone, because 1 its more readily available
and 2 it will prevent any diphenyl/triphenyl/xphenyl acetone from forming.
Hell, if your making straight amphetamine, you could even just go with
acetone as the solvent too, if you could come up with a good way to separate
the 2-aminopropane you'd make with the amphetamine. Given that this gunk has a
bp of 33 or 34 degrees at standard pressure, it shouldn't be too hard. Smells
like ammonia though... maybe you should "catch" it in HCl water when
you distill.
As with any distillation there will be some left over. Never fear,
2aminopropane (or "isopropylamine") is water MISCIBLE. Yes, the BASE
form is miscible w/ H2O! Amphetamine BASE is only
"slightly" soluble in water, so if your really a purist you can
dissolve your "mostly amphetamine some 2aminopropane" in ether and
backwash with water maybe ONCE. Then precipitate the crystals with dry HCl or
H2SO4?
Question is, how much ammonia and reducing agent are you willing to waste
on making 2aminopropane?
Purification by Crystallization
From: csc@pilot.njin.net (Sean Casey)
For a purification by crystallization of any of the HCL salts of ephedrine
and related illegals, I'd suggest a two solvent system with methanol and
methylethylketone. This tends to occlude a slight amount of solvent so keep
your crystal size small and grind and dry the result. Both these solvents are
easily available if you know where to look.
I wouldn't suggest ethanol or acetone as they tend to easily collect H2O;
this can happen unexpectedly and when it does, their solvency power will
greatly increase, redissolving your crystals. Be careful as methanol is toxic;
don't get it on you or breathe the fumes.
Read a lab handbook about two-solvent purification by crystallization.
Fascinating stuff.

Street Knowledge
Very scientifically unsound, but interesting nonetheless.
Street Doses
An average wrap of speed contains less than 10% Amphetamines, (often as low as
2%) and over 90% of adulterants.
Coloration
From: jkenner@cello.gina.calstate.edu (Jason Kennerly)
Methamphetamine in its pure hydrochloride salt form is colorless. However,
products on the market today are often not colorless. The following is a table
of some common impurities and the colors associated with them. Note: There is
no doubt a segment of the dealers who will add food coloring or some other
such color to their drug to make it more appealing, with the philosophy that a
brightly-colored product may sell better than an off color product. This is
relatively uncommon however.
- RED: The product was made from pseudoephedrine, and the red coloring of
the tablet was not adequately washed away (it is difficult)
- ORANGE: Ephedrine sulfate was used, and some of the sulfate was reduced
to sulfur.
- PURPLE: Iodine from a phosphorus-iodine reaction was not washed out.
- GREEN: Copper (or other metallic) salts somehow made their way in to the
mixture, probably due to the reaction vessel used in the manufacture.
- BROWN: Oxidized red coloring (see above), or tablating agent was present
in the reduction.
Sometimes "speed" is present as waxy rocks that almost seem wet, but
do not dry out properly. I am not sure what the cause of this is, but its most
likely some form of oil, either formed in the reaction or left over from a
very poor solvent. It may or may not be harmless depending upon what it is.
This oil is often removed with acetone, but ethyl-ether would be better suited
for this as it dries faster.
Pure methamphetamine HCl melts at around 170c (338f ). The crystals can be
carefully chopped and mixed with sodium carbonate, and when the resulting
powder is heated (and the methamphetamine HCl melts) CO2 and
methamphetamine base vapor is given off. This is probably one of the more
effective ways of smoking meth if you are careful, however the hydrochloride
salt is often the form smoked as the base form is often an oil and is
difficult to store, transport, and work with. Smoking the HCl form is OK if
you don't mind a small quantity of pyrolysed drug.
d-methamphetamine is, by nature, optically active. l-methamphetamine is
also optically active, but in the "opposite" direction. You can test
methamphetamine HCl for optical activity with the greyish-clear plastic pieces
from a pocket video game. Dissolve the methamphetamine in distilled water,
then place one of the optical filters (the grayish clear things from the games
LCD display) in front, and one in behind of the solution. Rotate one filter,
and note the angle that is brightest and the angle that is darkest. If many
"swirlies" appear, either use a different vessel to hold the
solution in, or make sure the solution is well stirred. After you have done
this, repeat the procedure with distilled water. A handy thing to use as a
"calibration" of sorts is to extract the l-desoxyephedrine from a
Vicks Inhaler (which is l-methamphetamine), and run this test on it as well.
RESULT:
- Same as water: DL-methamphetamine (or other inactive) Most likely made
from P2P (methamphetamine) or DLPA (phenylalanine). The DLPA-crank may in
fact only be dl-amphetamine. Might be 100% cut [read: nothing] also...
- Same as Vicks: You've been ripped off ! -or- there's so much unchanged
ephedrine as to cancel the dextrorotary effects of the meth (l-ephedrine,
when reduced, is dextrorotary (see explanation elsewhere)
- Opposite of vicks compared to water: DL-methamphetamine. Dextrorotary
product is almost certainly methamphetamine (or extracted dexedrines?) as
its is not worth the trouble to get other dextrorotary precursors or
resolve dl-amphetamine...
- Worth Noting: Cathinone and Methcathinone, when dissolved in methanol,
will become racemic due to the nature of the molecule (keytone). I'm not
sure what other conditions cause this but I am aware that it happens
easily, so methcathinone from the black market is almost definitely
racemic...
The EPHEDRINE/CAT TEST
Its probably not too uncommon that some guy screws up a synthesis, but by some
chance gets a partial yield. Or a dealer uses Ephedrine as cut. The problem
with Ephedrine (far more so than pseudephedrine) is its beta-agonist
properties - it raises blood pressure and pulse far more per "unit of
high" than methamphetamine.
It is advisable to become familiar with the many ways of synthesizing
methcathinone from (pseudo)ephedrine, as just such a procedure can be used on
freshly produced methamphetamine to verify that the (pseudo)ephedrine was in
fact reduced.
The smell of basic methcathinone has been reported to resemble that of
"pistachio ice cream". Suffice to say that it is sweet, pleasant,
and to a cat-head, nirvana. You should become familiar with this as well, in
order to be able to know if suspected methamphetamine is in fact actually
methcathinone.
The "BURN TEST" [residue test]
Methamphetamine HCl is heated on a piece of foil over a flame. It should first
melt (at over 170c) then begin to fume. Often the fumes will ignite. All
amphetamines will pass this test that I am aware off, including the
over-the-counter l-isomer present in vicks inhalers (the *only* way to check
this is to check optical activity , either by resolution or by actually
measuring it with optical filters). Methcathinone HCl has a higher melting
point than methamphetamine HCl (like over 190c at least) and a characteristic
smell, giving it away in an instant. Residue left behind may be by-product or
"cut", there's no good way to tell which... Suffice to say that if
there is more than a very small amount left afterwards, there is either cut or
by-products present.
The TASTE TEST [illegal without prescription snicker snicker]
Methamphetamine has a very bitter taste. Amphetamine has a bitter taste,
followed by some degree of numbness. This isn't the most useful test in the
world, especially considering it relies upon subjective senses too much IMHO,
but it may help discern the product. Methamphetamine is also more active on
serotonin that amphetamine according to net resources.

Sometimes 'speed' is present as waxy rocks that almost seem wet, but do not
dry out properly. I am not sure what the cause of this is, but its most
likely some form of oil, either formed in the reaction or left over from a
very poor solvent. It may or may not be harmless depending upon what it is.
It is more than likely the "didesoxyephedrine" referred to by Emde,
a product of the coupling of two radicals of the reduced ephedrine or
pseudoephedrine. It appears to some extent in almost all syntheses relying on
reduction and typically appears at the very end of the process of forming the
HCl salt by bubbling HCl through the mixture. And no, I haven't forgotten my
promise to post this paper. The scans just sucked when I tried to scan as text
(5 pages magically became 10-15 of scrambled text). I am currently trying gif
type scans. The *oil* may be removed, as you stated, by washing with ether.
However, it will never dry out as completely one might suspect. Even drying
under heavy vacuum leads to only a temporary solution. Once it is exposed to
air it quickly becomes an oil again. Often this is a brown color as you stated
for other by-products. As far as the rest of the post, I find it very useful
and agree with it completely.

the body. Thus you are smelling fatigue, not meth.
- "Made from poison"
- Made from several toxic chemicals; this does not mean it is itself
poisonous. For example, drinkable salt water can be made from lye and
muriatic acid.
- "Used to cut other drugs"
- Overstated in this role. Usually something much cheaper (and less clean)
is used.

THE TRIED AND TRUE
HOME PRODUCTION METHOD FOR
"METHAMPHETAMINE"
Written and tested by: The Leftist.
What to do with it once you have made it.
Take a ball about the size of a lead pellet, and wrap it in tissue, and
swallow, or you can put it in capsules and use it. You can smoke it, mix it
with vitamin B-12, and snort it like cocaine. You can also sell it, for about
$65-70.00 a gram, and don't forget to cut it. Remember, this is pure stuff!!
List of chemicals and materials
- Dilute Hydrochloric acid--> This may be purchased at the hardware
store. It sold as a brick and driveway cleaner. They call it muriatic
acid.
- Sodium Hydroxide--> This, you probably already have. It's called
"lye" at most places; it's drain cleaner.
- Ethyl Ether--> You'll probably have to make this. Don't worry, it's a
breez Just go to your local K-mart or Auto parts store, and get a can of
that "STARTING FLUID" it comes in a spray can. It's used for
cold weather starting of gasoline engines.
- "VICKS" nasal inhalers--> USE ONLY VICKS!! No other kind
will work that I know of. These are at any drug store or grocery, etc..
You need 12 of em, but don't buy em' by the dozen, unless its winter time,
then you can just say yer from some nursing home, and you're stockin up
for the patients. Otherwise buy em' 2 at a time, if possible. Get a friend
to help you. The druggists at the drug store usually will know what's goin
on if you buy quantity.
LIST OF EQUIPMENT
- Two large eyedroppers
- ten small glass bottles
- one large glass or porcelain bowl
- coffee filters
- one small jar with a top
- one Pyrex baking dish
- one glass test tube.

PLEASE! DON'T SMOKE IN THE SAME ROOM WHEN YOU DO THIS. OPEN A WINDOW IN THE
ROOM IF POSSIBLE. FOLLOW THESE INSTRUCTIONS EXACTLY. THIS RECIPE HAS BEEN
TESTED AND THIS IS T BEST WAY TO DO IT. DON'T TAKE SHORTCUTS, AND DON'T EVEN
START TO DO THIS UNLESS YOU HAVE ABOUT 3 HOURS SPARE.
PREPARING ETHER!
(DO THIS FIRST)
Take one of the small bottles and spray starter fluid in it till it looks
half-full. Then fill the rest of the way with water, cap the bottle and shake
for 5 minutes. Then, draw off the top layer with the eyedropper, and throw
away the water layer. Repeat this until you have about 3 oz. of ether. Put the
cap on it, and put it in the refrigerator if you can. (If you can't, don worry
about it) You'll use this in the procedure below.
THE TRIED AND TRUE HOME PRODUCTION METHOD
- Break open the inhalers, a pair of real sharp scissors does this good.
Place the cottons that were inside in a jar and close the lid. (Remember
you use all 12 cottons.)
- In the bowl, combine 1- 1/3 oz. water and 2/3 oz. muriatic acid. Shred
cottons in this solution, and knead for 5 minutes with hands. (ALWAYS BE
SURE THERE'S CLEAN RUBBER GLOVES on your hands.) You can do it bare-handed
if you' got tough skin. Squeeze all juice out of filters after you knead,
and throw em away.
- Filter the remaining liquid into the quart jar. It will be necessary to
this several times to get that awful smelling oil out. The chemicals in
the inhalers have been bonded to the HCl, and the oils have been filtered
off. Throw the filters away.
- Pour enough of the solution into a small bottle to fill it 1/3 full.
Save any leftover juice for the second batch.
- Pour 1/4 teaspoon of the lye crystals into the bottle and agitate. Do
this carefully, as the mixture will become hot, and give off a gas. Repeat
this step until the mixture remains cloudy.
- Fill the bottle from step (5) up the rest of the way with ether. Cap the
bottle, and agitate for about 8 minutes. It is very important to expose
ever molecule of the free-base to the ether for as long as possible.
- Let the mixture settle. There will be a middle layer that is very thick.
Tap the side of the bottle to get this layer as thin as possible.
- Remove the top layer with the eyedropper, being careful not to get any
of the middle layer in it. Save the top layer, and throw the rest away.
- Fill a bottle half-way with water, and about 10 drops of acid. Pour the
top layer from step (8) into the bottle, and cap it. Shake the bottle for
2 minutes. When it settles, remove the top layer and throw it away. The
free base has now been bonded to the HCl/water mixture.
- If there is anything left from step (3), repeat the procedure with it.
- Evaporate the solution in the Pyrex dish on low heat. You can do this o
the stove, but I have found that if you leave it on top of a hot-water
heater (like the one that supplies hot water to your house) for about 2-3
days, the remaining crystals will be Methamphetamine.
Some notes:
Police are now calling this the "New Cocaine".
It is very easy to become delirious off the ether fumes, so be sure you are
well ventilated, I mean it!!!
Small, aspirin, or experiment bottles seem to work the best for smaller
batches. The measurements are not exact, so you don't have to be either.
In step 9, be sure you don't use too much water. Remember, this is the
water you have to use to evaporate.

(WARNING!) This recipe is bogus! YOU WILL NOT HAVE METHAMPHETAMINE! You
have simple extracted pseudoephedrine! All this stuff will give you is
engziety(sp?)...
There are better recipes out there but if you cant get your hands on sodium
borohydride and a reflux condenser then don't even mess with this recipe!
But the ETHER extraction method is as true today as it was then!
From: ez026264@dale.ucdavis.edu (Speed Raver)
One, from Phrack magazine, is the "tried and true method" for
prepping meth from Vick's nasal inhalers. Vick's nasal inhalers contain
"l-desoxyephedrine," another name for "l-methamphetamine."
The l- isomer of methamphetamine is the relatively inactive one, usable as a
(mild) nasal decongestant. The d- isomer is the one that every one wants and
that Uncle Sam has declared is just too cool for any one except doctors.
The procedure described would extract the l-meth from the inhalers and
collect it and that's it. I'm sorry, but the Isomer Fairy can't wave her
magick wand and reverse the chirality of the molecule. The only way to change
between the two isomers is to oxidize the l-meth into phenylacetone, condense
it with methylamine, then reduce it. Sorry, but soaking inhalers in HCl then
separating the "juice" with Et2OH just won't do it. You'll get
l-meth and that's that.
The same recipe (for extraction of l-isomer), reformulated:
List of chemicals and materials
- Dilute HCl - also called Muriatic acid - can be obtained from hardware
stores, in the pool section.
- NaOH - also called lye - can be obtained from supermarkets in the
"drain cleaner" section. "Red Devil Lye" recommended.
- Ethyl Ether - aka Diethyl Ether - Et-0-Et - can be obtained from engine
starting fluid, usually from a large supermarket. Look for one that says
"high ethyl ether content", such as Prestone.
- Desoxyephedrine - can be obtained from "VICKS" nasal inhalers.
These are found at any drug store or grocery, etc. They contain 50mg of
l-desoxyephedrin e per container. Also known as methamphetamine. 6
containers will give 300mg of l-desoxyephedrine.
- Distilled water - it's really cheap, so you have no reason to use the
nasty stuff from the tap. Do things right.
List of equipment
- a glass eyedropper
- three small glass bottles with lids (approx. 3 oz., but not important)
- one should be marked at 1.5oz, use tape on the outside to mark it
(you might want to label it as ether)
- one should be clear (and it can't be the marked one)
- a Pyrex dish (the meatloaf one is suggested)
- a glass quart jar
- sharp scissors
- clean rubber gloves
- coffee filters
- a measuring cup
- measuring spoons
Preparing your reagents
Preparing Ethyl Ether
WARNINGS: Ethyl Ether is very flammable and is heavier than air. Do not use
ethyl ether near flame or non-sparkless motors. It is also an anaesthetic and
can cause respiratory collapse if you inhale too much.
Take the unmarked small bottle and spray starter fluid in it until it looks
half-full. Then fill the rest of the way with water, cap the bottle and shake
for 5 minutes. Let it sit for a minute or two, and tap the side to try and
separate the clear upper layer. Then, draw off the top (ether) layer with the
eyedropper, and throw away the lower (water) and cloudy layer. Place the ether
in the marked container. Repeat this until you have about 1.5 oz. of ether.
Put the cap on it, and put it in the freezer if you can. Rinse the other
bottle and let it stand.
Ethyl ether is very pungent. Even a small evaporated amount is quite
noticeable.
Extracting l-desoxyephedrine
- Break open the inhalers, a pair of real sharp scissors does this well.
Place the cottons that were inside in a bottle (the unmarked one) and
close the lid. I use 6 cottons.
- In the Pyrex dish, combine 2/3 oz. water and 1/3 oz. muriatic acid.
Shred cottons in this solution, and knead for 5 minutes with your gloves
on. Squeeze all juice out of filters after you knead, and discard them.
This step bonds the HCl to the meth, forming the HCl salt (what you want).
The salt is soluble in water, and thus dissolves.
- Filter the remaining liquid into the quart jar. It will be necessary to
this several times to get the awful smelling oils (check the packaging if
you are interested in which ones). The chemicals in the inhalers have been
bonded to the HCl, and the oils have been filtered off. Discard the
filters and clean the Pyrex dish. Remember to wet the filters with
distilled water before you pour, otherwise you'll lose some product.
- Pour enough of the solution into the clear bottle to fill it 1/3 full.
Save any leftover juice for the second batch.
- Pour 1/8 teaspoon of the lye crystals into the bottle and agitate. Do
this carefully, as the mixture will become hot, and give off hydrogen gas
and/or steam. H2 gas is explosive and lighter than air; avoid any flames
as usual. Repeat this step until the mixture remains cloudy. This step
neutralizes the HCl in the salt, leaving the insoluble free base
(l-desoxyephedrin e) again. Why do we do this? So that we can get rid of
any water-soluble impurities. For 3 oz. bottles, this should take only 3
repetitions or so.
- Fill the bottle from step 5 up the rest of the way with ethyl ether. Cap
the bottle, and agitate for about 8 minutes. It is very important to
expose every molecule of the free-base to the ether for as long as
possible. This will cause the free base to dissolve into the ether (it
-is- soluble in ether).
- Let the mixture settle. There will be a middle layer that is very thick.
Tap the side of the bottle to get this layer as thin as possible. This is
why this bottle should be clear.
- Remove the top (ether) layer with the eyedropper, being careful not to
get any of the middle layer in it. Place the removed ether layer into a
third bottle.
- Add to the third bottle enough water to fill it half-way. and about 5
drops of muriatic acid. Cap it. Shake the bottle for 2 minutes. When it
settles, remove the top layer and throw it away. The free base has now
been bonded to the HCl again, forming a water soluble salt. This time,
we're getting rid of ether-soluble impurities. Make sure to get rid of all
the ether before going to step 11!
- If there is anything left from step 3, repeat the procedure with it.
- Evaporate the solution in the Pyrex dish on low heat. You can do this on
the stove or nuke it in the microwave (be careful of splashing), but I
have found that if you leave it on top of a hot-water heater (like the one
that supplies hot water to your house) for about 2-3 days, the remaining
crystals will be Methamphetamine HCl.
If you microwave it, I suggest no more than 5-10s at one time. If it
starts "popping", that means you have too little liquid left to
microwave. You can put it under a bright (100W) lamp instead. Microwaving
can result in uneven heating, anyway.

Catalytic Reduction
From: ez026264@dale.ucdavis.edu (Speed Raver)
A more credible sounding one mentions that "methamphetamine is
prepared by the calalytic reduction of pseudoephedrine in acetic acid"
blahblahblah and then goes on to describe, not catalytic reduction via acetic
acid, but reduction with sodium borohydride. I'm sorry to say that no method
attempting to directly reduce (pseudo)ephedrine's hydroxyl group is going to
work. You can't expose it to a strong acid, or a weak acid, or sodium
borohydride, or even lithium aluminum hydride and expect it to reduce at all.
As with the Vick's Inhalers "recipe," you get a lot of SOMETHING,
but it ain't d-meth. All you'll be left with is your (pseudo)ephedrine and a
bunch of acid, lithium, and/or sodium and lotsa hydrogen gas. This is because
the hydroxyl group (the OH in ephedrine) is on a very acidic carbon (the first
carbon away from the ring) and a hydroxyl group is very basic. If the hydroxyl
were on the second carbon from the ring (the carbon with the amine group, the
NH2 or NHCH3), there might be some chance, but it's not and there's not.
You're not getting a basic group off an acidic carbon without a fight, and
acids, borohydride, and LiAlhydride aren't gonna fight that hard.

I'm sorry to say that no method attempting to directly reduce
(pseudo)ephedrine's hydroxyl group is going to work.
Your post was interesting, but this is not quite true. Direct hydrogenation
over Pd or Pd on a carrier is well known and facile. You add a little
perchloric, phosphoric or sulphuric acid, which esterifies the-OH group that
you're complaining about.
Thus making the intermediate halide via SOCl2, like you mentioned, is
unnecessary.
