I don't drink, smoke, do drugs, and a cup of tea is about the limit of my caffeine intake.

My brain is very precious to me, and if I do anything that might damage it, there's no way to fix it, or get a new one, so I try to stay away from anything that could kill brain cells, rewire things, etc...

But, that's just me. I'm pro legalization, etc... People should be free to get high if they want.
