There are two basic street distribution models: freelance and business. Describe both the freelance model and business model of drug distribution.
Consider the typical relationship between street level dealer and drug user. The drug user (consumer) and the drug dealer (retail sales person) engage in a mutually consensual transaction where the user receives a commodity (illicit drug) in exchange for an accepted payment (cash, property, etc). If we were to disregard the facts that the commodity has been deemed contraband and illegal by the government and consumption of the product has been deemed physically and socially destructive to the buyer, this is simply a business transaction no different than buying a Snow Cone from an ice cream man. If a drug deal occurs between two mutually consenting adults, how does this hurt anyone other than those individuals who want to engage in this activity?
