I honestly don't care if people smoke w/e, its not affecting me and its their choice. It does present a bad image sometimes and often gives teenagers like moi a bad stereo type. Still, you're over reacting. There are far worse things in the world than smoking weed or drinking (for example).

I would personally never do it myself cuz I for one hate trends and think its stupid. But until its hurts me, blow ur braincells to bits for all i care
