Getting a script for Marinol

[mfqr]

Yeah, I'll obviously show that but I'm thinking I need to educate them on the fact that I'm going to fail for THC when I take this script.

Yeah, take your prescription with you, and explain to them why you're taking it, etc... and that it is legal. You tell them you're going to fail it because of your prescription, and that's all you gotta say. The rest is up to them.
