Maybe that's why some of the dope smokers I hung around called it "herb". Makes it sound healthy. And the word "dope" is probably also somehow racist, but not to me.
There's a scambaiter bit where the "victim" starts smoking weed in the western union office just before he's going to read the numbers to his nigerian.
Nigerian: no no! Don't do it!!! Stop!!!
Victim: oh, its safe, it's an herb....its a vegetable!
