mushrooms

Jacob Sullum:

In the new study, conducted by researchers at Johns Hopkins, 30 "hallucinogen-naive adults reporting regular participation in religious or spiritual activities" were randomly assigned to a group given psilocybin or a group given Ritalin. The subjects "were encouraged to close their eyes and direct their attention inward." Two months later, the two groups were switched; another control group of six subjects received Ritalin in both sessions. In questionnaires two months after the psilocybin sessions, "the volunteers rated the psilocybin experience as having substantial personal meaning and spiritual significance and attributed to the experience sustained positive changes in attitudes and behavior consistent with changes rated by community observers."

To which non-hallucinogen-naive adults may respond, "Duh."


You can get the actual paper here. For those of you that don't spend a significant portion of your time reading the pharmacology literature, Psychopharmacology is what those of us that do fondly refer to as a "real" journal. (Peer review and all that. This ain't High Times is what I'm saying.)

The spin being put on the story is instructive--not so much on the issues of scientific interest raised by the study as much as how the underlying premises of U.S. drug policy ultimately stifle real inquiry. NIDA director Nora Volkow is already in ass-covering mode (and considering who's in charge in DC these days, I can hardly blame her):

Although there is no evidence that psilocybin is addictive, its adverse effects are well known...Psilocybin can trigger psychosis in susceptible individuals and cause other deleterious psychological effects, such as paranoia and extreme anxiety.


Meh. So can church.

She goes on to imply that NIDA didn't know they were funding psilocybin research, which may be true (to use controlled substances, you have to be licensed by the FDA, not NIDA), but I'm not buying it. Giving human subjects a Schedule I substance is kind of hard to keep under the radar.

The default position of U.S. drug policy is that molecules (drugs) are either "good" (which is to say, FDA-approved--or in the case of nicotine and ethanol, lucrative tax generators) or "bad" (which is to say, not officially approved and/or prohibited). The sheer lunacy of assigning what amounts to moral values to particular arrangements of carbon atoms ought to be obvious on on its face, but perhaps not...

My point here is that the ability of certain classes of drugs to induce profound feelings of introspection, empathy, and insight is hardly news. In the western world, people have been talking about it for decades. (Naturally, other cultures have been aware of this for centuries.) That serious scientists have finally gotten around to replicating a study done in 1962--and are making news by doing so--is something I find more sad than anything else.

There is bottomless potential here to understand ourselves better. While so many neuroscientists toil away pretending that our brains are just like computers, we have ignored for nearly half a century the possibility that some simple little molecules can replicate such a fundamentally human experience as transcendence.

Some of the reluctance to go down this road may stem from a fear of reducing life's experiences to a series of chemical reactions. Perhaps. But my thought is...

So what?

So what if falling in love or religious ecstasy can be understood on a neurochemical level? Does that actually diminish the value of the subjective experience? I'd venture to say that people with firsthand knowledge that their experience has been manipulated would say that it doesn't matter much.

Actually, I don't have to venture. From the report:

Thirty-three percent of the volunteers rated the psilocybin experience as being the single most spiritually significant experience of his or her life, with an additional 38% rating it to be among the top five...

It's great to see a study of this kind designed and executed so carefully and published in a decent peer reviewed journal.

If only there was more of this kind of work....I could be a volunteer.

So what happens if you're participating in such a trial and you have to go in for drug testing for work? Is it legally defensible considering the government knew about it and authorized it?

Well, I think if you enrolled in this study knowing you faced drug testing at work, you should probably be fired for being an idiot anyway.

That said, nobody tests for psilocybin. It is eliminated from the body very quickly, and there are no data (that I'm aware of, anyway) indicating that people use it habitually.

Most pre-employment drug screens are for the "NIDA 5" which are cocaine, opiates, PCP, amphetamines, and cannibus. All of these--with the exception of cannibus--will clear your system in a few days. The people these tests tend to catch are either 1) habitual pot smokers who didn't think ahead, and 2) people with a serious drug problem (i.e., they can't lay off it long enough to pass the test.)

Them, and the false positives.

As a sometimes psychonaut, I can say that reducing this sort of spiritual experience to material causes has profound and jarring consequences for people who might otherwise be predisposed to conceptualizing their understanding in more objective terms.

To be honest, I cannot begin to understand how you couldn't agree that reducing spiritual experiences to non-spiritual causes would seriously undermine the obvious psychological benefits conferred by a belief in transcendent God.

A great deal of happiness is born of the delusion that we have discovered some secret window to the truth world. That is the foundation of confirmation bias and all the other nasty heuristics that cloud our thinking but embolden us to commit ourselves to one life path versus the infinite number of potentialities.

Doing mushrooms is the single most spiritual experience in my life. That's sad.

OK, I've oversimplified a bit. Put it as you have here, and that much is obvious.

What I find interesting about this study in particular is that they went out of their way to select spiritually inclined people as subjects. So this is a population especially predisposed to view whatever it is that happens to your brain when psilocybin is present as a spiritual experience. And based on how they report their results (to the extent that a "spiritual experience" is something that can be measured) it appears that is exactly what happened.

I wouldn't presume to know how they reconcile this with the knowledge that they were chemically primed (to be precise--the knowledge that they might have been primed, since this was a blinded study), but it certainly seems not to have bothered them much.

Clearly, the same study in a population of professing atheists would be instructive. And it ought to be done.

As to the issue you raise of the psychological benefits of believeing in God (or to put it more broadly--of the human tendency to ascribe meaning and design to random events, which covers God and a whole lot of other things people believe)...well, that probably deserves a post or two of its own...

Suffice it to say that I am not convinced that where someone falls on the believer/skeptic spectrum is entirely a matter of choice. So I'm not sure that being told it's all a matter of neurochemistry will matter much to most people anyway.

I think the folks that would force humanity to evolve beyond supernaturalism are as deluded as the most committed creationist. They are, as you've pointed out, working against evolution itself.

Me, I just want to understand how the brain works for my own edification.

I don't even know what it would mean to wish I never knew what I (think I) know now.

But I am not sure whether or not I want to go around sharing what I (think I) have learned.

Thanks for the response. I needed to hear it.
