yeah, i knowa dude that will sell pre rolled joint or blunt to noobs, just cause they cant roll their own. Usually a blunt is a twin, and a joint anywhere from a .7 to a gram. he sells for 20 and 10$ accordingly.

i once had a guy try to sell me a roach though. i was seshing with my friend in the spot that all the kids at my school go to, and one guy asks"yo you wanna buy this roach? its really dank" i told him no, and his friend just gave it to us anyway haha.
