2C-B is 4-bromo-2,5-dimethoxyphenethylamine. It's the
phenethylamine analogue of DOB. The 2C is because its had a 2-carbon chain
sticking off of the phenyl ring (which is why its a phenethylamine instead of an
amphetamine), and I *assume* the B is because of the Br atom in the 4 position.
Doses are 12-24mg, Duration is 4-8 hours. Doses of 100mg have been taken safely.
2C-B seems to be an extraordinarily colorful hallucingen similar to LSD --
apparently somewhat analytical and dissasociative in higher doses or in those
sensitive to those effects.
Quote from Ecstasy: The MDMA Story...
[begins with a quotation from Alexander Shulgin]:
2C-B... is a tool... which ties the mental processes directly and
constructively into the physical soma. The analgesic effects experienced with
many, if not most, psychedelic drugs, are not present with 2C-B. On the
contrary, there is increased body awareness of every kind, including skin
sensitivity, heightened responsiveness to smells, tastes, and sexual
stimulation. One experiences increased consciousness of physical health and
energy, or, on the other hand, sharpened awareness of any body imbalance or
discomfort. 2C-B allows for rich visual imagery and intesnse eyes- closed
fantasy without the cluttering up of the mental field with too much
elaboration... It is a superb tool for learning and growth.
[...] At high doses (above 30 mgs.), 2C-B is intensely hallucinogenic, and, like
any major psychedelic, can be frightening for certain people. In small doses, it
becomes a mild sensory enhancer but does not have the strongly empathogenic
qualities that MDMA has.
Perhaps the best use that has been found for 2C-B is as a synergist with MDMA.
When taken together, the MDMA pushes the non-specific 2C-B reaction in a more
warm and emphathetic direction. Because 2C-B is a psychedelic drug, and
therefore not fully predictable, its action can take the user in many different
directions. But if the set and setting are right, 2C-B can enhance the desire
for sexual orgasm during an MDMA experience. The synergy of the two substances
can on occasion be a true aphrodisiac.
Shulgin writes in PiHKAL:
"The most successful reports have followed a program in which the two drugs
are not used at the same time, nor even too closely spaced. It appears that the
optimum time for the 2C-B is at, or just before, the final baseline recovery of
the MDMA."

DOB is 2,5-Dimethoxy-4-Bromoamphetamine. The only
chemical difference is the addition of an extra carbon to the chain. This turns
the phenethylamine into an alpha-methyl-phenethylamine (because the addition of
a carbon means attatching a methyl group to the alpha carbon of the
phenethylamine) also called a phenylisopropylamine or simply an amphetamine.
DOB has a potency of 1.0-3.0 mg and duration of 18-30 hours. It's very similar
to LSD. It seems to be more colorful than LSD and less dissociative than 2C-B
based on the reports I've read.

2C-D (LE-25): 2,5-Dimethoxy-4-Methylphenethylamine.
This is the 2 carbon homologue of DOM (2C-B is to DOB as 2C-D is to DOM). The
difference between 2C-D and 2C-B is simply the replacement of the Br atom with a
methyl group.
2C-D has a potency of 20-60mg and a duration of 4-6 hours. Seems to also be very
colorful. Shulgin notes: "Wow! This particular compound is what I call a
pharmacological tofu. It doesn't seem to do much by itself, always teasing,
until you get to heroic levels. But a goodly number of experimental therapists
have said that it is excellent in extending the action of some other materials.
It seems to boost the waning action of another drug, without adding its own
color to the experience." At 150mg+ it appears it might be a full blown
2C-B-like psychedelic, however. No info on the toxic dose.

DOM (STP): 2,5-Dimethoxy-4-Methylamphetamine. Again,
simply the addition of an extra carbon to the chain to turn the phenethylamine
2C-D into the ampehtamine DOM. And the replacement of the Br atom in DOB with a
methyl group would give you DOM also.
DOM has a potency of about 3-10mg and a duration of 14-20 hours. This was first
synthesized by Shulgin, and is what he calls his "Problem Child" (in
reference to Albert Hofmann's name for LSD). It gained a considerable amount of
use in the 60's and people taking 30mg+ (a whopping dose) had some very
dissasociative, bad trips. It was known as STP, which stands for the motor oil
additive actually, but was also known as "Serenity, Tranquility and
Peace". From the descriptions it seems LSD-like, with possibly even more of
a head-trip. 5-10mg seems *much* more appropriate from the descriptions with
very good effects. Only at higher (20-30mg) doses does it appear to get really
nasty.
And for chemical comparison, MDA and MDMA: 3,4-methylenedioxyamphetamine and
3,4-methylenedioxymethamphetamine respectively... They're somewhat similar to
DOM and DOB -- all the ring substituents need to be knocked off and replaced
with the 3,4-methylenedioxy ring. Then for MDMA you've got the addition of a
methyl group to the nitrogen amine.

MDA: 
MDMA:

Also we might as well throw in amphetamine if you all haven't figured
out what that should look like yet (replace the NH2 with NHCH3 to get
methamphetamine -- identical substitution as between MDA and MDMA). Also, if you
knock off the CH2 from amphetamine, you'll get phenethylamine which is the
prototype chemical for all the drugs I've listed so far, although itself its
inactive.

amphetamine:

And just for kicks here we have good old LSD which looks nothing like all these
other chemicals:

Hope you enjoyed that. Chem dweebs please check to make sure I got everything
correct. I didn't have time to go over this with a fine-toothed comb.

based on the reports I've read. The index of safety is probably something like
over 1,000 times the effective dose.
This figure is probably based on animal experiments described by Shulgin in
Pihkal. However, he goes on to say that the index of safety is probably much
lower than this. He says there are numerous reports of overdoses causing
vascular arterial spasm, and gives one verified account of a couple who thought
they had MDA and took quantities appropriate for that compound... i.e. around
100 mg. The woman died, the man lived after convulsions and a week in a coma.
Since the standard dose is 1-3 mg., the lethal dose is more like 30 times the
effective dose.

Well, in a thread recently, there was some talk aabout bromo mescaline, and
mention was made of the entry in the Student Handbook of our esteemed
institution that deals with the drug in question. Well, it is Reed folklore that
tells us that bromo mescaline was first synthesized here at Reed (BTW, it is not
folklore that Dr. Demento graduated from Reed), but the drug is real, to which
several friends can attest. Since I have the ol' Student Handbook right in front
of me, I'll tell y'all what it sez.
From _The Reed College Student Handbook_, in the "Drug Article That Ate
Reed College", by Marty Smith:
Bromo-mescaline. The most terrifying hallucinogen known to man. The effects last
3-5 hours, the visuals are awe-inspiring and the head trip is light, usually.
The catch is, first, for it to act like bromo, you have to snort it. This is
really intense, because in about two to five minutes, you're tripping you ass
off, the world is melting. The incredible speed with which this happens is one
of the things those who like it like about it. However, when it gets up your
nose it hurts. This is probably an understatement. It's really amazingly
painful. You'll be suprised that you would actually do this to yourself. It has
been described as having red hot knives shoved up your nose, or being kicked in
the face by a psychedelic horse. You may briefly entertain notions of dying.
This all dies down after about twenty minutes, though, and you're lucky there
will be no nausea at all afterward. (It helps to have eaten a starchy meal about
an hour and a half earlier.) Otherwise, you might have about 20 minutes of mild
nausea. The visuals are real good. To have visuals this intense on acid you'd
have to be on so much that you couldn't talk. On bromo you could discuss them
reasonably coherently.
A word about dosage. One hit is one fourtieth of a gram. This is a fact. Do not
say something stupid like, "Oh, let's do a lot," and hoot up a couple
of lines the size of your thumb. I have some friends who did this, and they
ended up lying under some bushes, at night, in the rain, unable even to yell for
help, and now they will not do drugs for the next five million jillion years.

That's the straight dope (none of the many puns intended).

Sure. And table salt releases sodium and chlorine in your body, so you will
both catch fire and suffocate if you take it. Adding halogen atoms to
psychedelic amines can significantly modify their potency, duration, and
effects. Read Alexander Shulgin's PIKHAL for an extensive discussions on
halogenated substituted phenylethylamines.
yes, i believe that "bromomescaline" 2-CB aka CBr... 2,5-dimethoxy-4-
bromophenethylamine. the reason why it probably burns going up your nose is that
it may lack any kind of anaesthetic action (unlike MDA, MDMA, and particularly
cocaine), while still being in the form (probably) of a hydrochloric salt (where
the HCl comes from).
culled from the MDMA FAQ: CBr is 2,5-Dimethoxy-4-Bromophenethylamine. The
"sometimes frightening" part probably comes from taking more than the
full dose, and the literature suggests that with larger dosages come
disproportionately larger responses, unlike some other psychedelics we all know
and love. I've had very enlightening experiences with CBr, and they grew better
in quantum leap fashion. + wonderful and gently insightful (semi-wilderness,
daytime, friends).
+ profoundly sexual with glimpses of bird-animal forms (indoors, nightime,
lover) minor telepathic imagery.
+ sexual and shamanic, native american imagery (indoors, day-night, alone).
+ profound native american imagery (indoors, night, after cannabis, friend)
actually slept a bit (too much cannabis) and awoke to the most wonderful visuals
(friend in other room - ditto).
+ full-blown spirit animals all night long (desert, night, friend, good THC 1/2
way thru trip) - mountain lion (very playful) and eagle most prominent two deer
(incredibly loving), a wolf (very brief), fantastic living plant spirits,
entities in mountain, mucho native american imagery, et. al. very telepathic
with friend. brief teleportation/desert-zoom experience. understood the
ancients' fascination with constellations. imparted with sudden knowledge in
extreme detail - confirmed later by ex-lover, scared ex-lover shitless.
My last experience with CBr changed my life in many profound ways (for the
better). With THC and a little concentration I can get back to some of those
places. With no THC and a lot of concentration I can get back to some of those
places. Remember.
I believe CBr is recognized as an enthogen and an entactogen, and unfortunately
it's now Schedule 1. :-( Put this one on the top of the list of drugs to be
legalized.

Subject: bromo
Hi:
There has been quite a flow of stuff on the subject of BROMO on alt.drugs entry.
Maybe you can post some parts of the following that might answer some of the
comments, questions, or errors being put out there on the topic.
(1) Bromomescaline is without doubt 2C-B. The dosage, the duration, the nature
of the experience, all seem consistent with this assignment. Also, as you have
indicated, the replacement of a methoxy group (of mescaline) with a bromo atom
gives the isomeric structure (a little rearrangement needed) of 2C-B.
(2) It releases bromic acid. Of course not. Bromic acid (HBrO3) is an unstable
chimera which is substantially unknown. Probably what is meant is that it
releases hydrobromic acid (HBr) but then there is no experimental evidence that
HBr is released either. I suspect that the bromine atom stays on the drug
molecule all the way through the kidney, and that there is no release of this
element at any time in the body.
(3) It is illegal, or a scheduled drug. No so. 2C-B was added to the German law
in January of this year, but in the US it is still an unnamed drug in Federal
law.
(4) It burns on snorting (insufflation). It sure does, but this is most likely
due to the fact that it is extremely insoluble in water, and probably sits on
the mucous membranes for quite a while until it dissolves and is absorbed. And
until this happens it irritates and blisters the skin at the sites where the
solid particles of the drug happen to settle. Once absorbed, the pain
disappears, and the effects start. A challenge to this would be to snort the
acetate or the hydrobromide salt, both of which are quite a bit more soluble in
water. These should have the same psychological effect, and they should act even
more quickly (no slow dissolving) and act with little or no pain.
I would love to know who in the wide wide world of information input discovered
the term bromic!! It cannot believe it has any merit.
Can you drift some of this on to the world of alt.drugs and satisfy this search
for information?
Thanks.
Sasha
