Bordered by eight other states and intersected by multiple interstate and state highways, Tennessee is both a destination and transport locale for a wide range of illicit drugs. Tennessee is thus a user and transshipment state more so than a production base of illicit substances, with the notable exception of domestically grown marijuana. Tennessee consistently ranks as a top 10 marijuana producing state. According to the Drug Enforcement Administration 2009 State Fact Sheet, however, the majority of drug trafficking in Tennessee is attributable to Mexican traffickers and organizations importing cocaine, methamphetamine, marijuana, and, to a lesser degree, heroin. Club drug use and pharmaceutical diversion are additional drugs of increasing concern in the state.
