A TV crew came over 10 years or so ago, on the anniversary of the discovery of LSD, and those guys were trying to push me towards saying how bad it was. They wanted me to talk about the dark underbelly of the drug culture. And I said, I'm not going to talk about that because I've never seen it, except in kids doing stuff that I don't know about and I'm not interested in... I've never taken crack and I've never taken ecstasy; none of us has. I don't want to take some strange drug and end up chewing my tongue for 12 hours.
