First off let me state that i do not use pot or any other drugs( I have tried pot a few times but i hated the way it made me fill) Ok here is the thing Bruce didn't somke pot but he did eat hash brownies.Also smoking pot doesn't affect martial arts ability,look at the pro wrestler Rob Van Dam he is a martial artist and is probably the best wrestler out there right now and he smokes alot of pot.And finally nobody in the history of the world has ever died from pot, in other words you can't od on it.
