You just gotta be careful when dealing with people you don't know. Personally, if you don't know the people then DON'T GO ALONE!! That's a bad idea and should never be done. Also, have your bf or some kind of guy to go with you so if the dealer or people with the dealer try to start shit with you the guy can back you up and if he needs to, kick the guys ass. Seriously, just be smart when scoring weed.
