"Washington is a distribution center for both licit and illicit commodities in the Northwest due largely to its geographic location-bordered by Canada and the Pacific Ocean-and its multifaceted transportation infrastructure. Private vehicles, boats, and commercial trucks are frequently used to smuggle drugs into Washington and transport drugs into and through the state. Couriers on commercial and private aircraft, commercial buses, and passenger rail cars also are used by traffickers, but to a lesser extent. [...] Mexican criminal groups are the dominant transporters of illicit drugs into Washington. These groups transport wholesale amounts of methamphetamine, cocaine, heroin, and marijuana into the state from Mexico, California, and Oregon. Caucasian criminal groups and local independent dealers as well as Asian criminal groups-primarily Vietnamese-and outlaw motorcycle gangs (OMGs)-particularly Hells Angels-smuggle significant quantities of Canada-produced marijuana into Washington."
