Pot may have some beneficial properties, but ‘pot’ is not a single chemical. Marijuana is a cocktail of chemicals all with different properties that can make them harmful or helpful. The chemical that gets you high is not the same chemical that can be used to treat glaucoma. Arguing that pot should be legal because of its medicinal properties is like tell a sick person to eat moldy bread because it may contain penicillin. The useful ingredients should be isolated and used separate from the rest from the harmful junk. As for its use in tia chi, I cant really say, I’ve never used. What I can say is that nothing very profound or insightful has ever come out of any of my friends that smoke pot. I’ve never been told or read any useful philosophical truths that have come out of the mind of a smoker. No pothead I have ever met was more in tune with him self and the rest of the world, they just seem aloof and somewhat vacant. The lighter users I know are just party people who don’t do it search of universal truths, but rather as an aid to help understand the intricacies of The Matrix. So I don't see how pot is any use at all. Correct me if I’m wrong and forgive me if I come off as sarcastic, it’s not the way I’d like this to be interpreted.
