If anything, those exotic "street" stories full of violence and danger seem awfully romanticized to me; they certainly have nothing to do with any experience of drug culture I have ever had.
Actual neighborhood-dealers in my neighborhood are more like the one depicted in the article, than the "corner" style inner-city dealers you see in movies and on TV. They might not be hustling around NYC selling to business people in office buildings, but they aren't "on the corner" packing a gun and paying off cops either.
If you're in SF, walk by the corner of Turk and Leavenworth and you'll have quite a few entrepreneurs of a different sort offering you "Roxies and Ps" or "Chiva".
Of course the problem with that is that a large percentage of those readers will leave the article with the message that "not all drug dealers are bad, some of them are like me." That's how you end up with cocaine/crack sentencing disparities.
The people sitting on the corner slinging dope is itself an image, and may not be reflected in reality anymore. Especially with police wise to that kind of behavior, surely it makes sense to be able to blend in?
Have you been in a bad part of town lately?
The places to buy drugs are liquor stores and car washes in bad neighborhoods. Plenty of people standing around willing to sell you $20 worth of your drug of choice.
Why do you think so much gun violence occurs in those areas?
this covers the end we rarely hear about and is far more interesting as it's far removed from the street.
