A recent CAMH Monitor survey found that 9% of young adults in Ontario drive after using cannabis, compared to 6% who drive after drinking. The survey also revealed declining rates of non-medical opioid use and increasing concerns around mental health.
Researchers found that cannabis users with schizophrenia have higher brain activity and correct answers than those without prior cannabis use. The study suggests that cannabis use can imitate the cognitive weakness leading to schizophrenia in non-psychotic individuals.
Researchers report on cannabinoid hyperemesis syndrome (CH), a little-known but costly effect of marijuana use, characterized by cyclic nausea, vomiting, and abdominal pain. CH can lead to expensive diagnostic tests and ineffective treatments, with some patients requiring multiple hospital visits and costing up to $30,000 in workups.

Research warns that highly potent marijuana and synthetic marijuana pose a real threat to pregnant women's unborn children. These substances contain high levels of THC, which can interfere with brain development as early as two weeks after conception.
A recent study by University of Colorado researchers found that 73.8% of adolescents in substance abuse treatment used medical marijuana recommended to someone else. Regular use of medical marijuana began at a younger age among these patients, and they had more severe symptoms of marijuana abuse and conduct disorder.

An online survey of over 3,500 young adults aged 18-25 found that half had smoked cannabis in the past 30 days, with co-use of tobacco and marijuana highest among Caucasians and daily smokers. The study suggests that 'stop smoking' campaigns should factor in cannabis use to their treatment plans.
A recent survey conducted by UCSF researchers found that half of young adult tobacco smokers also use marijuana, with usage highest among Caucasians and rural residents. The study suggests that smoking cessation programs should take into account the effect of marijuana use in their treatment plans.
A recent study found that illicit drug use among 50- to 64-year-olds in England has significantly increased, with lifetime cannabis use rising from 1.0% in 1993 to 11.4% in 2007. Recent cannabis use also showed a substantial increase. Other illicit drugs used were less common.
