ScienceDaily Summary:

People with mental illnesses are more than seven times more likely to use cannabis weekly compared to people without a mental illness, according to new research.

WTR-RI Research & Analysis Team Note:

The ScienceDaily article also notes the study found that “… although cannabis use is generally higher among younger people, the association between mental illness and cannabis use was pervasive across most age groups” and that “… individuals with mental illness were 10 times more likely to have a cannabis use disorder.”
