"The production, distribution, and abuse of illicit drugs and the diversion and abuse of pharmaceuticals pose a serious threat to Utah. Methamphetamine, heroin, and cocaine are the most significant drug threats to the state-they are responsible for most drug treatment admissions, federal sentences, and drug-related violence. Drugs are commonly transported through Utah en route to other states due to its location between drug sources and destinations. Illicit drugs destined for northwestern states from Mexico, southwestern states, and California as well as those destined for the East Coast from California often are transported through Utah. Mexican criminal groups dominate the transportation and wholesale distribution of most illicit drugs throughout Utah. Street gangs distribute most illicit drugs at the retail level. Caucasian criminal groups, local independent dealers, and outlaw motorcycle gangs also are involved in transporting and distributing illicit drugs in the state."
