Methamphetamine impurities
« on: January 12, 2011, 09:02:52 pm »
What might be in meth that is flammable?  For example, fairly high quality stuff, obtained in large crystals, almost clear but kinda cloudy, certainly not glass grade or anything like that.  When a very small amount is placed on aluminum foil and held over a flame as a test, it melts and turns into white vapor very quickly, then at the very last second w/e is left bursts into flame for a split second, then goes out.  Leaves a very slight brownish residue on the foil.

Probably some kind of solvent that hasn't been completely washed off, right?  Any ideas?

Could just be the vapor itself catching fire? If you blow out a candle and hold a flame to the smoke it will catch fire and chase the vapor down to the wick and light the candle again.

I imagine one could smell the solvent coming off the crystals if indeed there was any remaining, unevaporated.  And I don't think the solvent could get trapped inside the crystals, but I could be wrong.  You could try crushing into powder and sitting it to air, to make sure?

Sounds kinda sketch to me.

IDK anything about meth and with that in mind,

I don't thin it would be a solvent because I imagine most solvents would have ignited earlier in the smoking process. On could try crushing a small amount to powder and placing it in a glass vessel in a hot(boiling) water bath until one would be reasonably sure that any solvents would have boiled out and then try the same test you tried before with the theoretically cleaned material.
One could also try redissolving the material in the solvent of choice and slowly rextylzing.

Keep in mind all I know of meth I learned from breaking bad :wink:

Most materials when divided finely enough, will combust. Smoke/vapor is pretty finely divided. It's not uncommon for meth vapor to flash when exposed to a flame. It's not burn proof by any means. ;)

If I saw this happen, it was because of a possible small hole in foil, or perhaps the flame goes right through cheap foil. 
Smoking off foil boats is fun, but the glass is the way to go.  Not that I smoke meth a lot.  The last time was months ago, and had a chore in mind. A paper had to be written about neurofeedback training positives vs. negatives of certain drug chems used for therapy, using four articles as sources. It must have been some strong stuff, because I got really high from sharing half of a gram of some shards.  I was too high.  After the final smoking session hours after the first, I couldn't even think straight. It was hard to write the paper, and to decide which quotes to use, etc.  I was hearing bells and whistles going off in my head all night.

If I had my way, next time meth is chosen to aid in chores, would not smoke it.  Oral would be a better idea, at a similar dose maybe.

there is nothing wrong or flammable with the meth in question.

quite simply, you are heating it too much.

do you know what a flashpoint is? its the temperature at which a substance ignites, versus the melting point.. which is where a substance turns from a solid to a liquid, and the xtyl lattice is broken down from heat.

flash point- the temperature at which a liquid will yield enough flamable vapour to ignite.

melting point- the temperature at which liquid and solid coexist in equilibrium; also the freezing point.

if you want to achieve a proper vaporization of meth, heat till the liquid forms and then lower the lighter... if your liquid boils, then your heating too much.

meth mp= 170-175

there is not a flash point defined for meth salts that i am aware of, but it has one... that much i am sure of, as you seems to have found it.

Lol I know the proper way to vape it, thanks, and when I do I use a proper pipe.  I was just testing a little tiny speck on a piece of foil to see how the residue came out, etc. 

Thank you for the info jboogie, that makes sense.

Re: Methamphetamine impurities - colored stuffs

 Not to steer the conversation away from this seemingly fruitless debate, but can anyone tell me anything a little more detailed about the nature of colored meth? So far I've come across green, blue and pink. Interestingly (and making me suspect the fact that it is inDEED meth at all) I've had entirely different psycho/physiological experiences with each. The green made my head buzz a little...and added a little bit of a vibrating/carpeting effect to my vision - won't be doing that anymore btw; the blue was EXTREMELY potent and brought me back to THE old days (ah to be young again); and the pink...well the pink kinda just makes sex happen ...and happen...and happen...you get the jist.

I've been told by numerous people that its just food coloring and placebo, but I'd like to hear a more professional opinion, preferably from more experienced users who have experienced the same.

Thanks, me droogies

iirc red/pink is from from improperly cleaned psuedo, the pills are almost always red and the smurf blue dope was rare before breaking bad but now its much more common. It may be due to a manufacturing method but more likely its just dye to ride the hype. Green, I'm guessing a copper compound.

i can tell you right from the get-go, the discussion of impurities found in street meth will far exceed the scope of this thread. there are numerous forensic reports that attempt to identify all the impurities, but with all the possible synthesis variations it will bee next to impossible to outline them all. i will attempt to define some impurities that would cause a different color other than white (and by white i mean clear, just clear isnt a color)

hmmm, where to begin... i guess first we should look at how meth is produced. for the sake of this post, i will keep the discussion limited to the reduction of secondary alcohols (i.e. pseudoephedrine and ephedrine) as this is how 95% of street meth is produced.

keep in mind that many of the statements about a samples quality in relation to color are purely subjective. state of mind and the quality of reduction play a major role in defining a 'good batch', so with that said here we go...

many times, the starting feedstock (pseudoephedrine) is isolated from cold medicines. in many of these medications, there are other ingredients such as foilants, antihistamines, binders and colorings. if the chemist (and i use that term loosely) does a shitty job extracting the pseudo (or worse yet, they GUPchuck.. Ground Up Pill chucking without first extracting) then the end product will bee adulterated with these other excipients. this is the first source of color found in some samples.

the dye on the 240mg brand name pills is a bright blue/green, and many times this dye will find its way into the end product. this meth will actually look blue/green from the start. it doesnt hurt anything per say, but it isnt what i look for in meth. i typically see this with people that utilize the SnB with brand name tombstones. sometimes the dope is good, sometimes ehhh... in this instance the color is neither here nor there when trying to analyse quality prior to ingestion.

next we have the antihistamines. the two most common are chlorpheniramine maleate and triprolidine. both of these are amines and have similar solubility properties as meth, so these will end up in the end product unchanged. their appearance isnt fully seen until the sample is melted and resolidified (cracked back, in tweaker talk). when the adulterated sample is cooled and rextylizes in the pipe, you will see that the xtyl is no longer clear or slightly yellow. instead it has a blue or green transparent tint to the xtyl. the triprolidine will leave a blue tint, thus is is commonly called 'smurf dope'.  chlorpheniramine maleate, on the other hand, will behave the same way but yields a green tint and thus the moniker 'leprechaun dope'. had the 'chemist' taken the time to prewash his feedstock in some dry acetone, neither of these antihistamines would bee present.

in addition to the above two, you also have loratadine. loratadine is different in that it can bee reduced, so the end product will contain the reduction product of loratadine as well as pseudoephedrine, called desloratadine. the appearance of desloratadine is not apparent as it creates no color change prior or subsequent to melting/rextylizing.

in either of the three cases, these antihistamines can cause other symptoms that can bee confused with the effects of the meth. lightheadedness and vertigo can bee caused from the high level of antihistamines present. or the low blood pressure or whatever else antihistamines do in large doses, so you must take that into consideration when criticizing the effects of a dose/hit/line or street meth. 

now we'll take a look at another source of fuckedupness that doesnt concern the feed stock at all. its that 'pink' dope... now, there are two types of pink dope that i have seen, and neither of them is what i look for in good street meth. the least common reason for the pink hue is a wonderful product called glo-tel. its a benign additive to anhydrous ammonia that binds to water (like your skin and eyes) and leave a nasty pink stain on everything it comes in contact with. its used to discourage people from jacking anny at the farm houses in rural america. i wont touch glo-tel dope... it will stain your veins pink from the inside out, no shit.. google it. you can see the pink in the pics. this is much pinker than the pink achieve by the next example...
glotel demo)

the second and most common reason for the pink dope is the over acidification of the freebase. your meth freebase must be converted to a salt before it can xtylize. this is mostly done using hydrochloric acid, by either 'gassing' or 'titration'. either method will produce a pink tinted dope that burns like fuck if you slam it and itches in your throat if you smoke it. it doesnt affect the potency of the dope, just the overall quality. again, if the cook (im not calling them a chemist anymore) knew what the fuck he was doing, he would have properly tested the pH instead of gassing the fuck outta his shit. pink dope can look a shade of red or even brown depending how much the dumb fuck overshot the pH. the residual acid can bee washed away with anhydrous acetone, fyi...

and what else..

people that cook dope with HI made from mbrp that do a shitty job filtering can have little brown or red specs... these dont dissolve in the spoon and they dirty the pipe. yuck...

oh, and another is the blue tint again. many cooks like using camping fuel as the non-polar, and many times this is dyed blue (its a military thing dating back to the korean war, another story) and if the end product isnt washed of the residual traces of this np it will appear greenish/blue, but on the outside of the xtyl, not inside...

one common mistake is using too much lithium or sodium in your birch. this tends to over-reduce the pseudo and makes the end product yellow/clear. this dope usually sucks ass, so i steer clear. this isnt to bee confused with 'lemon-drop' or 'peanut butter' crank... thats a whole 'nother story. one mans lemon-drop is another mans piss-colored crap... i wont get into the sematical debate over what either of those are, because there is nothing solid to discuss.

as a good rule of thumb: 'if it aint white, it aint right!' im talking about street meth you racist fuckers.. ok, fine.. this one works too: 'if it aint clear, its aint good gear!'

just remember the description in the merck and stick to that: 'Methamphetamine is a white, odorless, bitter-tasting crystalline powder' if it smells, isnt white, and isnt entirely bitter.. than something is not right. period.

what else... i cant think of anymore bullshit at the moment, but if i do ill throw it in this thread.

i hope that helps some... ;)

Also, I've seen reductions performed in steel soda kegs with the end product being green.

The only peanut butter I used to encounter was P2P related, the brown sugar was largely HI/RP related.

Back in the the late 70's & early 80's bikers would (not kidding) put their P2P goods in a 55g steel drum. They'd roll that thing into a river with a chain on it and split. If it didn't blow up or rupture, they'd pull it out and get busy when it was done. That lent color to the matter also.

thats the exact reasons i stayed away from p2p dope. i have seen the quality of ketone ranging from slightly yellow clear to dark red or orange... and that is what it looked like right after distillation. god knows what it looked like after being stored for a month or two buried in the dirt.


there have been reports of people intentionally coloring their meth like 'what i make is soo good i have to color it' which is a crock of shit.


i also meant to include in that last pamphlet that all this adulterants can bee removed with an efficient dual solvent rextylization over as long a period as possible. it is not uncommon to leave xtyls growing for a week to force impurities out of the lattice.

IDK anything about meth and with that in mind,

I don't thin it would be a solvent because I imagine most solvents would have ignited earlier in the smoking process. On could try crushing a small amount to powder and placing it in a glass vessel in a hot(boiling) water bath until one would be reasonably sure that any solvents would have boiled out and then try the same test you tried before with the theoretically cleaned material.

Yep, it is probably a carbohydrate type impurity from a poor quality cold pill extraction.
