I've smoked ten marijuana cigarettes in my life, and probably the last time I had one near my face was twelve, fifteen years ago. And the reason I did was because, since I do smoke, people would say, "Here, smoke this, you'll get high." So I smoked it, and it gave me a sore throat and made me sleepy. And I must either presume that that's what high means, or something was wrong. But I've never had a positive result from smoking marijuana. It just wasn't my cup of tea. And I never used LSD, never used cocaine, never used heroin or any of that other stuff.
