We have people on here that have posted those from the suburbs (and west virginia) are buying all the drugs and are the reason for Baltimores drug ills because they keep the dealers in business
Yes people do come in town and probably buy LOTS of drugs but Baltimore has plenty of its own home grown addicts (over 60,000) to keep the dealers very busy and profitable.
Here's a REAL link with a study on addiction, blacks have a higher rate of addiction 7.7% then whites 6.6%
The reason behind this they write is because drug use is correlated to education so the more dropouts you have the more addicts you will end up with. They also say metro areas will always have higher rates of addiction and of course more blacks live in concentrated metro areas.
