Although marijuana use has declined slightly, the threat associated with the drug is increasing because of the rising prevalence of high potency marijuana throughout the country and the expansion of domestic cultivation by Mexican DTOs into more areas of the country. More high potency marijuana is being produced at indoor sites in the United States, while high potency marijuana smuggling, primarily by Canada-based Asian groups, from Canada into the United States is also increasing. These Asian criminal groups are also expanding their distribution networks to control a greater portion of wholesale marijuana distribution, particularly the distribution of high potency marijuana. Moreover, improved cultivation techniques are now rendering high potency marijuana from outdoor cannabis cultivation.
