Well, this is just my insights based off my school, so don't go entirely analytical on me :P I'm going with just, the addiction idea for my area. I know people, good people that smoke even though I bet sure as hell they wouldn't/shouldn't. Then, there's also the people that are just high or stoned or whatever out of their minds and it doesn't even sadden me because they're already so far in that they can't be pulled out. I know this is a pretty bland statement, but the only smoker I know that I have any true sympathy for is my Grandmother of 80 years old. It just tears me apart that she's wasting her life with them and can't do anything to stop it.
