I enjoy a little marijuana here and there, especially since I'm allergic to alcohol and sometimes feel that I could go for a little something something to relax a bit while I'm not busy with something important.
Also, someone mentioned krocodil. I just want to say that nobody should be using krocodil. I read an article about it on the world wide web and krocodil, like most street drugs, will tear your life apart while the people who care about you experience pain and frustration while you continue to take krocodil. I saw pictures and krocodil also destroys the body physically, it's not a pretty site.
