I know since I've started smoking its definatly helped me. I've reached levels of awareness I never thought possible. And thats just weed, I've yet to try shrooms or anything else yet! When I smoke, I become more thoughtful and yes - perhaps more spiritual. I think things through much more, I am much more sensitive to my senses and to others. I feel and see things others are blind to. Like Sangharyan says, Buddha never intended us to worship and obey everything he's ever taught. he simply is saying "hey, this worked for me, try it out, or see what works for you." Buddha is pretty chill, yes?
