I don't believe pot should be criminalized the way it currently is. That said, I do believe smoking pot interferes with Buddhist practice in that it interferes with your direct experience with reality, just as any mind-altering drug would. That said, I believe there are plenty of things worse for one's practice than pot-smoking. That said, that doesn't make it not a bad thing either. That said, who the hell am I to judge?

That said, I use too many qualifiers :)
