well dude, i would try to grow my own stuff if possible like suggested. If you can't then heres what ya do: Put on some muscle/tone up so you can defend yourself a little better, stay alert even when your cool with the dealer and always roll with a good friend that will back you up, even if they have to wait in the car atleast they are to prevent what happened to you at the car. I always used to pick up at real bad spots in wilmington and watts and long beach and even though I felt extremely threatened by a grip of people over the years I never got mugged around the slangers pads

Peace
