What's the going rate for weed these days?

A bum/entrepreneur corners another guy in line for a concert.

Bum: "Hey man I only got $2 and tickets are $10. Can you help me out?"
Cornered guy: "Uhhh..... fine, here's $1."
Bum: "You know if you gave me 8, I could get in..."
Cornered guy: "Sorry dude... you're gonna have to get the rest some other way."
*Pause*
Bum: "You wanna buy some weed?"
