I wouldn't be surprised if that's not what started Humphrey Osmond (psychiatrist who came up with the word psychedelic) on the idea of treating alcoholics through psychedelic therapy.
I gave some to a good friend who's been a long term (10+ years) alcoholic, was starting to have trouble with his health through drinking, but couldn't find the willpower to stop (and he really wanted to). Three doses over the space of 8 months (one was a big dose, prob 400mg+), and he doesn't really enjoy drinking anymore. He's the 'star pupil' of the clinic that deals with dependancy problems, but hasn't wanted to confide in the people at the clinic, in case they stop seeing him in such a good light.
I don't like killing cacti, but I'd say the benefit he's got out of mescaline is definitely worth it. (Osmond had something like a 40-50% sucess rate in the late 50's/early 60's, but then psychedelics got a bad name, so any further research was stopped, despite having the best results out of any alcohol rehabilitation therapy - typical short sighted politicians). I would say, because of that particular action, that it should be looked at again, with the possibility of it's use by psychiatrists that specifically deal with alcohol dependance problems.
Psychedelics can be used in a clinical setting to benefit people; some psychiatrists are fully aware of that, but they're not the problem; it's narrow minded, vote whore politicians that need to be convinced of it...
