I did cocaine for about a year around the time of Sgt Pepper. Coke and maybe some grass to balance it out. I was never completely crazy with cocaine.

The medical argument for animal testing doesn't stand up. Even if it did, I don't think we should kill other species. We think we're so much better; I'm not sure we are. I tell people, We've beaten into submission every animal on the face of the Earth, so we are the clear winners of whatever battle is going on between the species. Couldn't we be generous? I really do think it's time to get nice. No need to keep beating up on them. I think we've got to show that we're kind.
