laziness, loss of food....possible short term memory loss oh yeah, and sometimes you can burn your eyelashes if you're too high
I've thrown up twice after eating too much from the munchies, and one time my heart was racing, but that's about it. Edit: Also, if you smoke it and don't vaporize it or eat edibles, you're inhaling carbon monoxide from the partially burned carbon atoms which is poisonous in large amounts (the only reason a weed overdose is even remotely possible).
U can smoke urself into a panic attack or paranoia if ur irresponsible or dont pay attention to how much ur smoking
the laws? people that abuse it? cartel involvement? lazy ass potheads? weed snobs are the worst! the munchies can be a real bitch yeah, there's a few things wrong with it
