A lot has happened since I published Version 3 of
the DXM FAQ; some of it has been good, some not so good. I'd like to take
a moment to address some of these changes and some of my concerns. I still
do not regret having published the FAQ, and out of all the feedback I have
received (including letters from physicians, scientists, parents, and just
plain druggies), less than one percent has been negative. The reasons I
gave for its publication still apply, but those of you familiar with v3.0
will notice that this version shows considerably less praise for DXM.
When I published the FAQ on Usenet (and then the
World Wide Web), it was my expectation that it would be of interest primarily
to psychonauts, experienced psychedelic users, and others who use drugs
for self-exploration and spiritual purposes. I knew, of course, that not
everyone who did DXM would use it with the intention of expanding the mind,
but I reasoned that, given the relative unpleasantness of consuming cough
syrup, and the "heaviness" of the DXM experience, most people would find
casual, recreational use of DXM unlikely. Things didn't quite turn out
how I expected.
Also at that time there was a severe shortage of
information from former DXM users about adverse effects of long-term use.
I had reasoned that long-term use was probably not a good idea, but probably
not terribly dangerous. Of the people I had interviewed who had used DXM
regularly, very few had any problem with it, and those who did recovered
when they stopped using it.
Since then there has been a great increase in DXM
use (or at least more people are talking about it). My concern that the
FAQ had started a "DXM epidemic" turned out to be mostly baseless; the
majority of new DXM users seem to hear about it the same way that DXM users
have always learned about it: from their friends. Some do learn about it
from the FAQ, but for the most part you have to know about DXM in the first
place before finding or understanding the FAQ.
As I have spoken to more and more users of DXM, I
have learned that more people have negative experiences with the drug than
I had expected. Most of these are simply people who try it once, decide
they don't like it, and never try it again. A few people, on the other
hand, seem to be greatly susceptible to DXM addiction and some of these
have suffered long-term health consequences. A very few may have suffered
permanent brain damage from extremely heavy use of DXM (e.g., an 8oz bottle
of Maximum Strength syrup every day). On the other hand, some people consume
the same amount for years seemingly without consequence. And while some
people can consume DXM regularly without psychological consequences, others
suffer from severe depression and psychotic breaks, even leading to a few
cases of suicide attempts.
This brings me to the most relevant new information
about DXM: Olney's findings of NMDA Antagonist Neurotoxicity (NAN). There
is great debate right now whether NAN is relevant at recreational doses
or not. In animals, the dosage required to induce NAN is far in excess
of the anaesthetic dose, and humans typically take sub-anaesthetic doses
of dissociatives. On the other hand, there may be danger with long-term
use at considerably lower dosages that the animal models do not show.
The data from human experiences are hard to interpret.
Many heavy PCP users suffer obvious cognitive and motor impairment; however,
PCP has neurotoxic effects (in particular in the cerebellum) not shared
by other dissociatives including DXM or ketamine. Ketamine is probably
a better approximation of DXM, but very few people have done large amounts
of ketamine for long periods of time. A notable exception is John Lilly,
who is a bit of a nut, but was probably a bit of a nut before doing ketamine,
and (at least the last time I checked) he doesn't seem to suffer from cognitive
impairment.
There are a few DXM users who have suffered long-term
consequences. Out of approximately five hundred current and former DXM
users I have heard from, three have suffered lasting cognitive impairment.
Additionally, there is one published paper on cognitive impairment from
chronic DXM use, although the author suggests an underlying temporal lobe
seizure disorder. DXM has been shown to increase the frequency of complex
partial seizures, and it's possible that it is the seizures, and not the
DXM itself, which is causing problems. Unfortunately, it has also been
suggested temporal lobe epileptics may also be more susceptible to dissociative
addiction. Hopefully much of this will be resolved in the next few years.
Until then, my official recommendation is not to
use DXM at all. Since I know this isn't likely to happen, my own personal
belief is that DXM is probably pretty safe when used occasionally (e.g.,
once or twice a month) at the lower plateaus, and rarely (e.g., once or
twice a year) at the higher plateaus. I have yet to hear from anyone who
used DXM with this or less frequency who has suffered any impairment, temporary
or permanent. Actually, to be technically correct, nobody using it once
a week for less than six months has ever seemed to have problems, but it's
always best to keep a wide safety margin.
Another thing to keep in mind is that DXM in the
upper plateaus is a considerably different experience than the lower plateaus,
and may be better suited to spiritual or ritual use. Even at the lower
plateaus, DXM is not really well suited as a frequent recreational drug.
So what do you do then if you find yourself in that
particularly human condition of ennui (for which psychedelics are a most
effective medicine)? Well, ideally I'd suggest you hop on a plane to Amsterdam
(or somewhere else where 2CB and marijuana are legal). Unfortunately this
isn't an ideal world, and flying across the Atlantic is outside the means
of most of us (including me). A more reasonable suggestion would be to
do your part to change the laws in this country so that psychedelics can
regain their rightful place as tools for mental, emotional, and spiritual
exploration and growth. Remember, the laws aren't going to change unless
we work to change them.
In summary, I'm not nearly as convinced that DXM
is a benevolent psychedelic as I used to be. It is in many ways considerably
more powerful (and certainly more dangerous) than LSD or mushrooms. Like
all psychedelics it can profoundly change you; unlike others, these changes
are not necessarily under your control, especially if you are not very
familiar with yourself. DXM can be a great tool for spiritual rebirth,
but it can also turn you into a paranoid, antisocial asshole. I still believe
that DXM has a place among psychedelics, but do understand that it is not
a replacement for LSD, mushrooms, 2CB, or even ketamine. It is a unique
and uniquely powerful mind-altering drug, and one which I think most people
would do best to avoid.
This document is a FAQ ("fack"), i.e., a series of
questions and answers. The term comes from Usenet, and stands for Frequently
Asked Questions. These are the sorts of questions
that people new to Usenet tend to ask frequently. When these questions
become frequent enough, the question and its answer may be placed into
the FAQ for the newsgroup (or for a topic within the newsgroup). A few
people use the term AFAQ (Answers to Frequently
Asked Questions), but most use FAQ to refer
both to a frequent question and to the document
This FAQ covers dextromethorphan (decks-tro-meth-OR-fan),
the cough suppressant commonly found in cough medicines available over-the-counter
in the USA and other parts of the world. Of course, dextromethorphan (DXM)
does more than suppress coughs; otherwise, there wouldn't be so much discussion
about it on Usenet. The bizarre truth about DXM is that it is a very potent
psychoactive drug when taken in sufficient quantities. So if you've ever
heard about people drinking cough syrup for fun, well, now you know why.
The trouble, however, is that most cough medicines
have other ingredients which can make you uncomfortable, sick, or dead,
depending on the ingredient and how much you take. Furthermore, even when
pure, chronic or heavy use of DXM may cause health problems. This document
is intended to combat potentially dangerous misinformation about the recreational
use of DXM, and to allow you to make an intelligent and informed decision
about DXM.
My own interest in DXM came quite by accident; once,
while sick with the flu, I misread the instructions on a bottle of cough
syrup and drank two shots from the included shotglass instead of two teaspoons.
Soon after I noticed that music and motion had become very satisfying experiences.
This left me puzzled, and my reaction was to go to the library and research
DXM through Medline, medical journals, and books.
Of course at that point I was hooked - not on DXM,
but on neuropharmacology. I decided to learn as much as I could about DXM,
and found it to be one of the most unique and interesting of all recreational
drugs in terms of how it works on the brain.
About this time I noticed a number of incorrect and
potentially dangerous posts (articles) about DXM appearing on alt.drugs.
So, I decided to gather the information I had and write a FAQ. It eventually
became much more than a FAQ, giving explanations and information in addition
to answers, but by then the name had stuck. The FAQ took me over 150 hours
to complete - I figured if I'm going to do it, I'd better do it right.
After publishing the DXM FAQ, the reports of DXM
use started coming in. People who had been using DXM but were uncomfortable
talking about "getting high off cough syrup" shared their stories with
me. Some were good, some were bad, some indifferent. I've been trying my
best to get all of these personal reports together into a coherent whole,
but this FAQ is written in my free time and I don't get paid for it (although
donations are acceptable :^).
Please note that it is not my intention to
get a bunch of people hooked on cough syrup (actually addiction is very
rare, but you get my point). It is my intention for people to know
the truth so they don't make bad decisions for lack of knowledge. DXM is
not safe and harmless; nothing is. Nor is it universally enjoyable;
in fact, some find high-dose DXM experiences terrifying. But I believe
that people can only make good decisions, or learn from bad decisions,
if information is available. So please, use your head!
