I do, I do it almost everytime its offered. I usually stay away from it for 2-3 days before finals (mostly for math). It doesn't kill, doesn't shrink your balls, doesn't permently effect memory, can't drive you insane, not physically addictive, and you wont act stupid after doing it because you stop going (whoa doing this is neat high!). You are also in control while high not like alcohol which you lose control at a certain point. This poll is a little off against others I have seen usually 66% have smoked or do smoke, here its about 50%. For the people who want to or can't find a dealer whatever... there are options.
1. Ask (everyone knows lots of people do it so you'll get a yea or a no)
2. Grow it yourself (many think this is hard... no its called WEED for a reason, it grows like weeds just about anywhere) You also can buy femal only seeds on the net. If you want to make it full of THC then you have to baby it.
Oh yea for those thinkin about eating it, expect to feel high for at least 6 hours. One crazy story about my brother is he ate 97 grams (about 3 ounces) with his girlfriend in 1 night!
