@Jonewest - Yeah, I know weed in particular makes guys more easily and intensely aroused. Guys have told me that when they're high even a single thought of sex could turn them on so bad they needed it right then and there. On the other hand, others have said it has the exact opposite effect on them. @Govindia - Yeah, what Jonewest is saying...not to mention your time. If they're truly your friend and they're making an income and you're the person enabling them to get to and from work, they should be paying for more than your gas given your financial situation.
I've been so fucked up lately I didn't even know it was the weekend.
