Cannabis can make you look like a Gritball.
We're all anxious enough about how we look without having to worry about the stained fingertips and teeth, stinking breath, and bloodshot eyes that come with smoking pot. People who smoke dope can look a little-well, skeazy. They might lose interest in their appearance. They can also get the munchies when they're high-and it's not exactly health food they binge on. They don't call that tire-shaped ring of flab around the middle of a pothead the "stoner's spare" for nothing.

I'm FUCKING angry right now. WTF! i've never heard of a 'stoner's 'FUCKING!!!' spare' before. they make all that bullshit up! i sent them an e-mail to educate them...I'm off for a joint to calm down!
