Illinois and Michigan had similar increases in the prevalence of cannabis use disorder between 2018-2019 and 2019-2020 with Illinois increasing from 2.0% to 2.6%. Other mid-west states (Indiana, Iowa, Missouri, and Wisconsin) and the US did not show the same amount of increase.


There has been an overall decrease in treatment admissions in 2020, including admissions for Cannabis Use Disorder. However, the percentage of all admissions where cannabis was the primary drug, did not fall as sharply as the overall decrease in admission rates.


Between 2018-2019 and 2019-2020, Illinois, Michigan, and the group of contiguous mid-west states all showed increases in alcohol use disorder, though the entire U.S. did not see this increase. It is not clear then how much of the increases in cannabis use and cannabis use disorder in Illinois are to the CRTA, to COVID, or to some other factor.


Compared with persons admitted to drug treatment in Illinois for other drugs, those whose primary drug was cannabis were more likely to be male, Black-Non-Hispanic, ages 18 to 35, have been referred to treatment from the criminal justice system and to receive treatment in an outpatient setting.


The most common co-occurring mental health disorders and substance use disorders for persons with Cannabis Use Disorder were a major depressive episode, serious psychological distress, suicidal thoughts, and alcohol abuse.
