A new international study shows that the percentage of young cannabis users gambling with risk of depression or suicidal behavior
Juvenile cannabis was used with an increased risk of depression and suicidal behavior in young adulthood, according to the first meta-analysis by a team of scientists at McGill University Health Research Center (RI-MUHC) and McGill University, in association with Oxford University and Rutgers University. -Camden, published in the journal JAMA Psychiatry today.
The conclusions were reached by a team led by Dr. Gabriella Gobbi, researcher in the Brain Repair and Integrative Neuroscience Program (BRANIN) of the RI-MUHC and Professor of Psychiatry at the Faculty of Medicine at McGill University, following a systematic review and analysis of international studies with 23,317 individuals. The results show that the use of cannabis in adolescence could adversely affect mental health, even in teenagers who reported no signs of depression before they start cannabis.
Little attention has been given to analyzing the impact of juvenile cannabis use on the risk of developing depressive symptoms and pest disorders on the juvenile brain, which is still being developed until the age of 25.
Risk is particularly elevated in North America, where young people have higher rates of cannabis use compared to their counterparts in other developed countries. Canadian youth represents 15-25 years of age and majority of users of all ages (comprising 20-33 percent) and reports more than 20 percent of adolescents in the US monthly use.
Results of attacks on suicide behavior
Researchers analyzed the risk of depression, anxiety, suicidal ideals and suicide attempts based on occasional cannabis consumption.
“The study suggests that diagnosis of depression in about seven percent of Canadians and Americans between 18-30 years of age is linked to cannabis, which means that depression is 25,000 young Canadians and 400,000 American t young people about cannabis consumption earlier, ”says co-author Nancy Mayo, Professor of Medicine and School of Physical and Labor Therapy at McGill University and scientist at the Center for Fruit Research and Evaluation of the RI-MUHC.
Rather, researchers reported a weaker association with anxiety.
“When we started this study we expected depression to be a comparable factor in cannabis consumption, but we were very surprised at the rates of suicide behavior. In fact, a significant proportion of suicide attempts are linked to cannabis, ”says Dr. t Gobbi, who is also a psychiatrist at the MUHC.
The need for public initiatives
The findings underline the importance of prevention initiatives aimed at educating teenagers on the risks associated with cannabis use while teaching them skills to combat peer pressure.
“It is clear that many young people who are eating cannabis are at risk of developing depression and suicide behavior, so it is very important that authorities are more proactive in campaigns for prevention,” says Dr. Gobbi. “We hope that the results will encourage public health organizations to put in place preventative strategies to reduce cannabis use among young people.” T
