People with mental illnesses are more than seven times more
likely to use cannabis weekly compared to people without a mental illness, according
to researchers from the Centre for Addiction and Mental Health (CAMH) who
studied U.S. data.
Cannabis is the most widely used illicit substance globally,
with an estimated 203 million people reporting use. Although research has found
links between cannabis use and mental illness, exact numbers and prevalence of
problem cannabis use had not been investigated.
