Canadian Study Says Cannabis Puts All Teens at Risk for Psychosis

Cannabis use directly increases the risk for psychosis in teens, new research suggests. A large prospective study of teens shows that “in adolescents, cannabis use is harmful” with respect to psychosis risk, study author Patricia J. Conrod, PhD, professor of psychiatry, University of Montreal, Canada, told Medscape Medical News.The effect was observed for the entire cohort. This finding, said Conrod, means that all young cannabis users face psychosis risk, not just those with a family history of schizophrenia or a biological factor that increases their susceptibility to the effects of cannabis.”The whole population is prone to have this risk,” she said. The study was published online June 2018 in JAMA Psychiatry.

Cannabis strength soars over past half century

Largest study on how cannabis has changed over time finds increased strength putting consumers at greater risk of harm

A new study from the Addiction and Mental Health Group at the University of Bath synthesized data from more than 80,000 street samples of marijuana tested over 50 years. The samples were collected in the USA, UK, Netherlands, France, Denmark, Italy, and New Zealand.

They found that THC concentrations increased in marijuana plant material by 14 percent and in marijuana resin by 24 percent, but CBD concentrations remained stable between 1970 and 2017.

Dr. Tom Freeman, director of the Addiction and Mental Health Group, and co-author Sam Croft, also from the group, say higher concentrations of THC increase the risk for problems such as addiction and psychotic disorders. They call for standard units of THC, similar to standard units of alcohol.

High Potency Cannabis Associated with Mental Health Issues in Adolescence

A study from the University of Bristol, the first of its kind to look at data from a general population sample, finds that those who use high-potency marijuana (10 percent or more THC) are four times more likely to report associated problems and twice as likely to report anxiety disorder, compared to those who use low-potency marijuana (less than 10 percent THC).

Smoking One Joint Can Induce Psychiatric Symptoms

A single THC dose can induce psychotic side effects, new review finds

Some people associate smoking marijuana with waves of euphoria or pain relief. But for certain individuals, consuming cannabis can lead to a far worse experience: According to a recent research review, a single dose of tetrahydrocannabinol (THC), one of the major active compounds in marijuana, can induce a host of psychiatric symptoms in people without a history of mental illness.


Understanding Opioid Use Disorder

Early initiation of marijuana (before 18 years) emerged as the dominant predictor. Decision trees revealed that early marijuana initiation especially increased the risk if individuals: (i) were between 18-34 years of age, or (ii) had incomes less than $49,000, or (iii) were of Hispanic and White heritage, or (iv) were on probation, or (v) lived in neighborhoods with easy access to drugs. Conclusions: Machine learning can accurately predict adults at risk for OUD, and identify interactions among the factors that pronounce this risk. Curbing early initiation of marijuana may be an effective prevention strategy against opioid addiction, especially in high risk groups.

Can cannabis really do all that? Weighing the literature on cannabis-based compounds for mental health disorders – Recovery Research Institute

Plant derived and synthesized cannabinoids including tetrahydrocannabinol (THC) and cannabidiol (CBD) are increasingly being prescribed or recommended for medicinal purposes, including for the treatment of mental health disorders and associated symptoms. Currently though, the uptake of these compounds to treat a wide array of mental disorders and their symptoms is outpacing the scientific evidence supporting their use.
