"Cocaine and heroin are Maine's primary drug threats based on their addictive properties, availability, and abuse. Cocaine is transported to Maine from several locations primarily in privately owned, borrowed, and leased vehicles and by way of public transportation. Maine health department data show that cocaine abuse remains stable. However, law enforcement reports that powdered cocaine abuse is stable while the conversion of powdered cocaine into crack and the abuse of crack are increasing in the state. Powdered cocaine is distributed throughout the state while most crack cocaine distribution is limited to southern Maine. [...] Dominican criminal groups operating in Massachusetts are the primary suppliers of cocaine to Maine. Most powdered cocaine dealers are Caucasian while most crack cocaine dealers are Hispanic, particularly Dominican. Heroin availability and use are increasing in the state, reflecting a trend noted throughout New England."
