It's self-indulgence essentially, and being around other "drop outs" (I don't really like calling anyone that) can make it seem like it's the right thing to do and you're somehow making progress by just drinking (when you're really just lying to yourself). It's a big trap- spirituality as a fad/fashion. I don't like to blame anyone stuck there (we really all are on our own journey, who's to say if it's right or wrong even if it looks like a big detour to me. Some people just aren't ready to face the truth, but at least being with the medicine will give them ample opportunity).
