Teenage marijuana smokers with mental health disorders are THREE times more likely to harm themselves, warns study
- U.S. researchers study more than 200,000 teens with mood disorders
- Ten percent of these have been found to have the diagnosis of ‘cannabis use disorder’.
- This condition is associated with the 3.28 times higher risk of non-fatal self-harm
Teenagers with bipolar disorder or depression who smoke marijuana are at increased risk for death and self-harm, a new shock has been found.
Mood disorders in adolescence have long been linked to dagga abuse and it has now been found that this addiction has a significant impact on the mortality rate.
Researchers from Ohio State University found that teens with a mood disorder and a cannabis habit are 3.28 times more likely to harm themselves and that 59 percent are more likely to die from all causes.

The study found that the risk of death due to an unintended overdose is 2.4 higher than in people who avoid the drug.
‘Marijuana use and addiction are common among adolescents and young adults with mood disorders, but the association with this behavior with self-harm, suicide and overall mortality risk is poorly understood in this already vulnerable population,’ says lead author Dr Cynthia Fontanella.
“These findings should be seen as states considering legalizing medical and recreational marijuana, both of which are associated with an increased disorder for cannabis use.”
The study, published in JAMA Pediatrics, assessed anonymous cases of more than 200,000 people between the ages of 10 and 24.
Cannabis use was observed in 21,040 adolescents with mood disorders, one in ten from the study group.

The study used cannabis plants that were professionally grown and carefully extracted and applied to models. According to the researchers, this means that smoking marijuana or using moderate oil offers no protection against Covid-19 (stock).
Cannabis abuse is more common in older people as well as black people and men.
During the seven-year observation period, participants were also thoroughly studied to determine the incidence of non-fatal self-harm, all-cause deaths, suicide, overdoses, car accidents, and homicides.
“We have also found that disorder for cannabis use is significantly associated with self-harm, including death by unintentional overdose and murder,” Professor Fontanella said.
“Unfortunately, although this observational study draws attention to these associations, it may not contribute to our understanding of causality or mechanism.”
The researchers say that young people with mood disorders are not only more likely to use marijuana, but that the drug can also worsen symptoms and affect treatments.
Reducing the rates of cannabis use and cannabis use can reduce the risk, ‘says senior author Professor Mary Fristad.
“Individual and family-based therapy models, including cognitive behavioral therapy and motivational enhancement therapy, have been shown to reduce cannabis use in adolescents.”
