I just received a copy of the article from the May issue of Harpers magazine, entitled "America's Altered States/ When does legal relief of pain become illegal pursuit of pleasure".
>From what little I've read so far, it looks like a very good
article, on liberties of altered states, politics of the War
on drugs, reviews of personal risks from different causes, etc.
So if you pass by a newsstand, consider picking up Harpers.
