ABSTRACT
Retailers of illegal drugs face many of the same concerns as retailers of legal commodities. M. Kleiman and P. Smith argue that there are theoretical as well as practical reasons to focus on the retail rather than the wholesale level of drug distribution. Cities without large-scale street drug dealing should go to great lengths to avoid developing markets. In a neighborhood drug market, transactions take place in locations where both the customer and the dealer feel comfortable. Enforcement efforts focused on fixed-site neighborhood sales include identifying the site and sealing the establishment. The periodic market, the profit at any specific location is small because sales can be made only at limited times during the day. The City of Philadelphia, for example, changed a pattern of one-way streets to make a drug mart in north Philadelphia more difficult to approach.
