Don't live in the city but got many friends that would drive to the city to cop ounces of dope and they had good connects. It always was pretty good IMO, yeah, dope potency goes up and down but my buddy regularly would get shit that was the best dope I've ever done, not to say I've tried dope from too many different places, just manly from the D and a few times I got dope from Chicago. Either way though, if you know someone getting 1/2 ounces or more from a good supplier, that's where it's at (unless you know his guy's guy lol.) My buddy bought 1/2oz's and ounces at a time and he'd give it to me before he cut it, that shit was almost too strong, I had plenty of my friends fall out on his dope. To begin with, they were already trying to be careful so they'd shoot only like 1/2 the amount of dope that they'd normally do, if even that much and they'd still accidently do too much, thankfully nobody ever died.
