There's actually some decent science behind using psilocybin to help break a cycle of alcohol addiction. And, marijuana does offer some benefits for a range of conditions - I think there is a danger, though, that using marijuana lessens your defenses - and you may end up drinking or using other, more harmful substances.

I might try mushrooms, though I currently have no desire to drink. My past experiences with pot left me with a "take it or leave it" feel, so I'm not interested in going down that road.
