I didn't mean to imply that the processes were even remotely the same, because obviously, they are not. However, I would still say that the only heavily used drugs that are prone to severe abuse that qualify as completely unnatural are PCP, methamphetamine, prescription drugs, and that weird new crap that's eating Russians alive called 'Krokodil'. Look that stuff up if you're in the mood to see what a real life zombie might look like. It's pretty damned foul what it does to the body.
As I said though, I am not a fan of anti-drug regulation at any level, against any drug. It just annoys me when potheads try to act like their drug of choice isn't a drug, when it actually is. I don't care where it comes from, it's still a drug by every single definition.
