'It's natural!' A stupid argument
According to many marijuana advocates, pot is "good" because it's "natural" while processed drugs are bad. What about tobacco? You don't have to process it to smoke it, yet it's clearly bad for you. Cyanide occurs naturally in peach pits. So is cyanide also a wonder drug that's going to save humanity? Snake venom is also natural. Would you like to get bitten by a rattlesnake?
