I'm personally excited to see what sorts of new treatments will come out of using psychedelics medically. I've always been on the skeptical side of medical marijuana usage in all but the most extreme cases, but I have a feeling that LSD and psilocybin can really provide mental turning points and help people break out of depression.

I'm very optimistic as well. My family has hard-to-treat depression and there's a lot of reason to be optimistic about psilocybin. Michael Pollan's "How to Change Your Mind" was a fantastic read.

It only makes me wonder what other possibilities have been out there but banned and therefore unavailable for study and experimentation. Luckily the days of censoring and hoarding information seem to be coming to an end.

Of course as a society we love the pendulum effect. We'll swing it too far and then it will come back the opposite way too far (so much for my optimism :-P)

everything is safe or unsafe depending on dose-age and frequency of use. click-bait stupid analysis / catchphrases /headlines about drugs are why the average conservative is quite rational in their approach to just thinking that the better advice for younger people is to simply abstain.

the same applies to coffee.

if you don't know how to use a drug properly you shouldn't use it.

saying it 'is safe' is nonsense. TOTAL ABSURD NONSENSE.

morphine is safe. it is used tens' of thousands of times a day by people in intensive care units around the u.s. , maybe millions.

'safe'.

nothing is safe. everything is safe. what isn't safe is listening to nonsense.

> I've always been on the skeptical side of medical marijuana usage in all but the most extreme cases,

Really? I've always found the milder claims fairly believable (fighting nausea or chronic low level pain relief). As an anecdote, I can attest to dealing with kidney stone pain well (rather than stopping the pain it reduced how much I noticed it) and it ended up more effective and felt less dangerous than the opiods I had used in the past.

Some of the more "miracle" claims, however, seem pretty suspect to me and I'd want some reliable reseach.

What makes you skeptical of so many claims?

This is NOT a trial that was designed to assess the safety of psilocybin. This was a trial meant to show that a particular dosage of psilocybin is /safe enough/ to pursue further research in that dose range.

This was a /phase one/ clinical trial.

Phase One: administer small doses under very close supervision in a tiny number of people to determine whether it's immediately dangerous, or safe enough /for further study/. They used 89 - initial randomization of 30 each to placebo, 10mg, and 25mg. That's a good number for a phase one trial. But when we look at the sort of things that start hurting people when released to market, they're the sort of adverse effects that go undetected in trials with thousands of participants, and would need an infeasible large trial (>10k patients) to detect.

This trial does not prove safety. This trial is meant to establish a dosing range that is /safe enough/ to participants to allow for further study. They found no "serious" adverse effects, in healthy volunteers - that is, not depressed patients. Can drugs like this have different effects in people w and without depression? Yes they most certainly can, in particular if those people are on concurrent medications (which they will be, since this is being developed for treatment-resistant depression).

“We wanted to look at the safety and tolerability profile of our psilocybin, and to look at the feasibility of a model where up to six one-to-one sessions are held at the same time." No they didn't /want/ to - they /had/ to. This is article is just a press release.

Phase 2 is generally a range of doses, within the range established in phase one, wherein we attempt to determine, to a rough level of accuracy, which doses show toxicity, which show therapeutic benefit, and at roughly what proportions. This phase is meant to determine what dose will be used in a phase 3 trial, if any dose exists with an appropriate proportion of therapeutic benefit to side effect.

Phase 3 - a dose (or couple of doses) of a drug in a regimen meant to reflect real-world proposed usage is distributed and compared against either a currently used drug or a placebo. Depending on how big an effect is expected, how common the disease, etc. we'd look at trials of hundreds to thousands of patients. This is the trial where we get a real sense of safety, side effect profiles, efficacy, etc. This is the make-or-break line for getting your drug to market.

Phase 4 "trial" - aftermarket surveillance. Goes on for years after a drug hits market, because there's no trial that comes to close to capturing the rare side effects that may be visible when applied to the general population.

This was, also, presented to a neuropsychopharm conference, not published data. Which is to say, they're ready to brag about it, but they're not ready to submit themselves to close scrutiny.

Thanks for this breakdown. Any thoughts on how this process might unfold for psilocybin as opposed to a drug that's subject to a chemical patent? Funding, timing, etc.
