Yep, Matt's right. I'm an abstainer for now. Smoked plenty in college. Then didn't for 22 years. Then smoked last summer with my sister, who was using it for chemo symptoms. Didn't keep that up, though, after I started med school. I was considering it for this summer since I'm on break, but it's such a hassle to obtain. And I'm looking at some rather big surgery in two or three weeks, so I'm going to keep my lungs clean and clear for that. If it were legal and easy to get, I'd be the first one in line.
