I just don't think teens should be allowed to control what goes into their body...
I hate seeing a perfectly healthy kid from gradeschool end up a braindead loser (from smoking so much pot) just because they thought it was cool.

thats the only thing that gets to me... other than that i guess I don't care if an adult chooses to smoke pot, cigarrettes are terrible, and more addictive, and they're not illegal.
