from experience, if you really want to find dope down in the city, ive been all over the east side of the US and finding drugs there is nowhere easier than detroit. All you have to do is look the part, go to a shitty gas station, don't be afraid, and walk by a group of dudes standing outside, theyre all over the place and they will hound you telling you they got boy(heroin) and girl (crack). trust me, they will ask you, i am confronted almost 99% of the time i go into a gas station. and if you ask, theres no doubt the most random person you ask will know someone, and they want your business, so unless youre an idiot, theyre gonna hook you up cause they want you to come back with more money.
