THE PRESENT STUDY had a variety of origins, all centered around
my long term interest in altered states of consciousness. For
several years I had read many anecdotal accounts of what it was
like to be intoxicated on marijuana,[1]
talked with many students and acquaintances (hereafter referred
to as pilot subjects and informants) about what being intoxicated
was like, and tried to do some theorizing that would make some
sense and order out of the many phenomena reported. What little
sense I have been able to make out of things in terms of theorizing
has been presented in Chapter 2. This
theorizing also made it clear that a systematic look at the overall
phenomenology of altered states of consciousness was vital. The
present study is an initial systematic look for one state of consciousness,
marijuana intoxication.
For several years I took systematic notes on various phenomena
reported for marijuana intoxication, and, based on these, a large
questionnaire was made up. The questionnaire used the current
language of marijuana users ("heads") as much as possible.
It was distributed with a covering letter that was intended to
be friendly and to induce cooperation among users both in filling
out the questionnaire and in passing questionnaires along to other
users. The text of the letter is given below.
To: ANYONE WHO HAS SMOKED MARIJUANA
MORE THAN A DOZEN TIMES
I usually start a letter with "Dear So-and-so," but
somehow greetings like "Dear Marijuana Smoker," "Dear
Head," "To whom it may concern," or anything else
like that sound pretty bad, so I'm skipping the greeting and getting
right down to the point.
One of my main research interests as a psychologist is the area
of altered states of consciousness. I am particularly interested
in investigating the psychological effects of marijuana, both
for their intrinsic interest and for comparison with other altered
states of consciousness. Reading the (scant) scientific literature
on marijuana is disappointing, for most everything is on the order
of, "Gee whiz, I smoked (or ate) grass, and I saw all sorts
of pretty pictures which can't be described, and gee whiz, etc.,
etc., etc." That's very nice for a start, but not very specific!
From preliminary talks with people who smoke marijuana, it is
obvious that there are many and varied effects, and that it would
be of great psychological interest to know what they are. Scientists,
as a whole, know practically nothing about the experience of smoking
marijuana. You do. The ideal way to expand our knowledge about
these effects would be to have people smoke it under a variety
of conditions, with known amounts and qualities of grass, and
then report on it. Even a rudimentary knowledge of the legal situation,
though, tells you genuine laboratory research on marijuana is
virtually impossible.
So I'd like to enlist your help as an expert; you've been there
and, I hope, you would like to see us really know something about
marijuana experiences on a scientific level, instead of just an
anecdotal level. Enclosed is a questionnaire. It has a few basic
questions about how much you've used marijuana, other drug experiences,
and so on, to get a little background. Then the main part consists
of over two hundred statements about possible experiences during
the marijuana high that have been selected from preliminary surveys.
I would like you to fill out the questionnaire and rate each of
the described experiences in terms of how frequently it happens
to you and how stoned you have to be to experience it. This is
explained more fully in the questionnaire.
If you will help by carefully filling in this questionnaire and
by passing more of these questionnaires on to other heads, what
will you accomplish? The following kinds of questions can be answered
from analyzing this data. What sorts of experiences occur when
stoned, with what frequency? How are they related to how stoned
you are? What kinds of differences are there between individuals?
Are there several different patterns of going up, or does everybody
go up the same way? How is the marijuana experience related to
experience with other drugs? How is it related to how long people
have been smoking? Are there certain more basic factors that account
for a lot of the specific experiences? And many other things.
O.K., I'm going to learn a lot, and so will the scientific community
when the results are published. What will you learn? The same
thing. I don't like the kind of research (of which there is too
much today) where the all-knowing scientist manipulates his stupid
subjects. You're acting as the expert, the explorer, and you should
be able to learn a lot for your trouble in helping me. Now, I
can't get your name and mail you anything (that would run the
paranoia level too high!), but it is common practice in science
to send reprints of research results to anyone who requests them.
If you will drop me a card in about a year (it takes that long
to analyze everything and get it published), I will send you a
copy of the results. No need to be paranoid on that, as I will
get lots of reprint requests from people who have nothing to do
with this study.
While we're on the subject of paranoia: you are able to help in
this study on the basis of your past experience. I am not
advocating that anyone smoke marijuana or do anything illegal
in order to be able to fill out this questionnaire, but naturally
you don't want to put your name on it! Note also that it is not
illegal to fill out a questionnaire. The questionnaire comes with
a stamped, return envelope so you can return it to me anonymously.
The data from the questionnaires will be punched on IBM cards,
and the original questionnaires destroyed as soon as possible.
The way these questionnaires are being distributed also insures
your anonymity. I don't know any marijuana smokers by name, so
I am simply putting these questionnaires out in places where marijuana
smokers may have a chance to pick them up, and just handing them
to people who might or might not know smokers, until this finally
reaches you, with me having no idea of the route. In turn, please
take as many questionnaires from whatever source you get this
as you think you can pass on to other marijuana smokers. The more
returns I can get, the more revealing this research will be.
I'm asking for about an hour or two of your time. In return, you
will eventually know a lot more about the psychological effects
of marijuana, and the scientific community will learn even more
(considering the starting level); hopefully this knowledge will
eventually result in more rational attitudes toward marijuana
use.
If you can't fill this out, through lack of time or experience,
please pass this material and any other sets of it you have along
to someone who can.
Many thanks!
Sincerely yours,
CHARLES T. TART, PH.D.
Because most users experience a variety of intoxication phenomena by the third or fourth time they use marijuana, I selected the cutoff of a dozen uses to define an "experienced" user. As noted in Chapter 4, all the users who returned the questionnaire were far above this minimal cutoff.
Do not put your name on this questionnaire or otherwise identify yourself.
The first two pages of the questionnaire are self-explanatory questions about your background, how much you've used pot, and your experiences with other drugs.
The rest of the questionnaire consists of statements describing a wide variety of experiences people have reported having while stoned. These descriptive statements have been taken from a wide variety of different people's accounts and it is unlikely that any single person has experienced all of the things described.
The statements are grouped into categories, such as Vision Effects, Hearing Effects, changes in Space-Time Perception, and so on. Some descriptive statements are relevant to more than one such category, but they are only listed under one, in order to keep this questionnaire as short as possible.
Each statement describes a particular kind of experience, for example, "I can see more subtle shades of color." The sense of each statement is that whatever effect is described, it is considerably stronger or somehow different when stoned than if you were experiencing it straight. That is, some of the things described can be experienced to some degree when straight but are reported to be much more intense or different when stoned. Even if the statement does not include the phrase "than when straight," this comparison is implicit in all the statements.
For each descriptive statement, you are to make two ratings.
The first is how frequently you have experienced that particular effect when stoned, judging against all the times you have been stoned in the last six months.[2] Circle the answer category that most closely describes how often you experience that effect. The categories, reproduced under each description, are:
Never = you have never experienced this effect.
Rarely = you've experienced it at least once, but it's not at all frequent.
Sometimes = you experience it between about 10 percent and 40 percent of the time.
Very Often = you experience it more than about 40 percent of the time.
Usually = if you experience it practically every time you get stoned.
These rating categories are approximate, so while you should use your best Judgment you need not try to count over all your experiences!
The second rating to make for each descriptive statement is one of how stoned you have to be to experience it (if you have experienced it at all; if you haven't, don't rate this for that statement). That is, there is an assumption that some sorts of things can be experienced if you're just a little stoned, while other things can't be experienced unless you're very stoned. There is a minimal degree of "stonedness" that you have to be at to experience a particular effect. The "How Stoned?" scale under each descriptive statement runs from Just, which is the smallest degree to which you could be stoned and know that you were stoned, to Maximum, which is the most stoned you've ever been after smoking a lot of high quality pot.
It is possible to think about the "How Stoned" rating as relating to the amount of pot you smoke (or eat), but this is only a rough parallel because of the variations in the quality of pot. Thus this rating scale is defined in terms of your own perception of how stoned you have to be to experience the described effect, and you are asked to make five discriminations of your degree of stonedness, with Just and Maximum at the low and high ends of the scale, and Fairly, Strongly, and Very Strongly as intermediate points.
To take an example, the first descriptive statement is, "I can see new colors or more subtle shades of color than when I'm straight." You might have this happen to you about half the times you get stoned (ignoring for the moment how stoned you are over all these times in the last six months), so you would circle the Very Often category. Then, thinking about how stoned you have to be to experience it, you might feel that it doesn't happen to you unless you're very stoned, so you'd circle the Very Strongly category. Thus you would be saying that you can't experience (or haven't experienced) this when you've been just stoned, or fairly stoned, or even when strongly stoned; but when you're very strongly stoned or maximally stoned you can experience the change in color perception.
It may be that you've experienced a particular effect at several degrees of "stonedness," but what you're rating here is the minimal level of stonedness you must be to experience it.
There is one other category on the "How Stoned" scale, marked LSD. You are to circle this category only if you have experienced that effect after having taken one of the very powerful psychedelic drugs like LSD, DMT, DET, mescaline, peyote, psilocybin, or STP. Thus there will probably be a number of things described that you've never experienced with pot but have with one of the more powerful psychedelics (if you've had any of the more powerful psychedelics).
There are a few questions where the two scales "Frequency" and "How Stoned" don't apply, and space is left for a descriptive answer.
There are a number of experiences that occur when stoned for which the opposite also occurs frequently; e.g., sometimes colors may be more intense and sometimes they may be duller. A bracket has been put in the left-hand margin whenever two questions are linked this way. Thus, you might find colors get brighter sometimes at a minimal degree of Very Stoned, and also that colors get duller frequently at a minimal degree of Just.
Finally, space has been left at the end for you to describe any effects you get from being stoned that haven't been mentioned in this questionnaire. In making up this questionnaire it was attempted to mention everything that people may have written about as happening while stoned, but some things have undoubtedly been missed, so this is your chance to complete the list!
Please rate the statements as accurately as you can. Whenever you feel that the way the statement is phrased doesn't quite fit your experiences, feel free to write in an explanation. If a statement makes no sense at all to you, put a ? beside it and skip it. It is understood that many of the experiences of being stoned are difficult to express in words!
Answer this questionnaire while straight, and when it is complete, seal it in the attached return envelope (do not put a return address on it!) and mail.
The envelope is already addressed and stamped.
It is so commonplace and trite on psychological questionnaires to say "Thank you" that I hesitate to say it, but l really do appreciate your filling this out!
