weed has been brought before. If you have a medical marijuana card, prescription, whatever, it's ok. Apparently the demons check your wallet for it first. If you have it, they leave you alone. If don't, well buddy, you're in for a wild evening.
edit: I remember the anti-rap stuff starting in the late 80's. I wish I could remember the article, but there was an Awake that condemned rap because (and I think I have the quote) 'they lyrics are spoken, not sung.'
It's such an insane thing to harp on.
