You know I'm starting to really doubt that you have any idea what you're talking about. I picked the About.com article to look at and all the negative side affects, aside from the inhalation of smoke (which I already listed as negative), are short term and only occur when you are high. The ones that were listed are actually what makes getting high enjoyable and most of those are only negative when taken out of context. I doubt you have even smoked pot before, because if you have, I think you would better understand what I'm trying to iterate. Try not to nag something you've never experienced, especially when it's not unhealthy.
