besides the actual smoking of weed, its not harmful at all. if you eat it there is no real harm done. you will have temporarily effected short term memory impairment, but that goes away once all the THC is out of your system. as for drugs in general, they never do you any real favors. i used to smoke bud all the time and still drink probably more than i should on the weekends, but i'd never criticize anyone for drinking/smoking, but it is something that could lead to unsuccessful patterns with your lifestyle. MODERATION. i think pot is just too trendy anyway lately... does no one eat shrooms anymore!?!
