As for the original post: I sure don't, but my boyfriend does. We'll smoke, then I'll lie down on his bed and read the Economist or a book or something (I love reading high) and he'll get up start running around taping shit to his walls or stapling shit to his ceiling. The only exception for me is if I smoke while exercising or doing something active, I get pretty energetic. Over the summer I took five-mile walks every day, hitter in hand.
