Marijuana Use Increases Psychosis Risk

Marijuana is the most commonly used illegal substance in the US and Britain. The evidence suggests it may not be as harmless as many of us would like to think. The risk of developing schizophrenia is given as one in a hundred, and if you smoke pot, that risk increases to 1.4 in a hundred.

Robert A Heinlein was a Libertarian

I'm celebrating the 100th Anniversary of Heinlein's birth, this month. His science fiction writings were formative for me. I read at least 10 of his books when I was in high school. The most memorable one of the lot was Stranger in a Strange Land, which was published in 1961. Recently the teenage son of a girlfriend of mine read the unabridged version of SISL. I could see by the light in his eyes that he grokked the truth of it.

But I didn't know until today that Heinlein was a Libertarian. I suppose I could have figured it out from the anarchist flavor of some of his writings.
