The discussion defines the "trap" as a one-way-in, one-way-out environment where the drug trade and music production are inextricably linked. A distinction is made between drugs sold for profit, such as crack and pills, and drugs consumed by the producers and artists, primarily "lean" (codeine cough syrup) and marijuana. The influence of the Black Mafia Family (BMF) is noted as a significant factor in the influx of money and the professionalization of the rap scene.
