I adore this website, but i've never felt the need to respond to a question before. I go to Yale, and, I must say, it is so easy to find weed here. But, overall, it's like that at any school. My little sister goes to a community college, and, if she is correct, those places are swarming with potsmokers looking to pay for their habit by selling a little on the side. Of course, the age issue presented in the question may be a hell of a challenge, you should do fine to discreetly ask people in a non-threatening manner (worked into the conversation; you should pick a topic that lends itself to pot-smoking): "oh my, I was watching those silly cheech and chong boys last night, and wouldn't it be fun to get high? Hey...have you ever tried that?" So on, so forth
