Marijuana Use Increases Risk Of Depression And Suicidal Behavior

Contrary to what advocates want us to believe, marijuana use isn't harmless. Like all recreational drugs, marijuana creates its "high" by affecting brain function. These effects can adversely affect the brain in many ways, which can lead to increased risk of depression and suicide ideation recent research involving young adults has found.[1] This research is consistent with previous research on all age groups, including seniors.[2][3][4]

Because of the potential long-term harm caused by recreational drug use, including marijuana, we recommend avoiding recreational drugs if you want to preserve good mental health.

Due to our work helping people regain good mental health, we publish research like this in the hope that it will help some people avoid the pitfalls associated with recreational drugs. Many people have a difficult enough time overcoming existing mental health challenges never mind adding recreational drug use problems. It's much easier to overcome existing mental health challenges like anxiety disorder and depression without recreational drug's influence. Adding recreational drugs like marijuana to the mix can make recovery that much harder.

For the sake of your mental health, avoid recreational drugs!

Increased Depression And Suicidal Behavior Risk For Young Cannabis Users

MCGILL UNIVERSITY HEALTH CENTRE

Adolescent cannabis use has been linked to an increased risk of depression and suicidal behaviour in young adulthood, according to the first meta-analysis by a team of scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University, in collaboration with the University of Oxford and Rutgers University-Camden, which is published in the journal JAMA Psychiatry today.

The conclusions were reached by a team led by Dr. Gabriella Gobbi, a researcher in the Brain Repair and Integrative Neuroscience (BRaIN) Program of the RI-MUHC and a Professor of Psychiatry at McGill University's Faculty of Medicine, following a systematic review and meta-analysis of international studies comprising 23,317 individuals. The results reveal that cannabis use in adolescence could harmfully alter mental health, even in teenagers who did not report any depressive symptoms before starting cannabis.

Little attention has been paid to analyzing the impact of adolescent cannabis use on the risk of developing depressive symptoms and mood disorders on the adolescent brain, which is still under development until the age of 25.

The risk is particularly elevated in North America, where adolescents have higher rates of cannabis use compared to their peers in other developed countries. Canadian youth aged 15-25 constitute the majority of users of all ages (spanning 20-33 percent) while over 20 percent of adolescents in the United States report monthly use.

Surprising suicidal behaviour findings

Researchers analyzed the risk of depression, anxiety, suicidal ideation and suicide attempts based on daily-to-occasional cannabis consumption.

"The study suggests the diagnosis of depression in approximately seven percent of Canadians and Americans between the ages of 18-30 is attributable to cannabis, meaning 25,000 young Canadians and 400,000 young Americans suffer from depression because of earlier cannabis consumption," says co-author Dr. Nancy Mayo, a Professor in the Department of Medicine and School of Physical and Occupational Therapy at McGill University and a scientist at the Centre for Outcomes Research and Evaluation of the RI-MUHC.

Researchers reported instead a weaker association with anxiety.

"When we started this study we expected depression to be a factor attributable to cannabis consumption, but we were quite surprised about suicide behaviour rates. Indeed, a significant percentage of suicidal attempts are attributable to cannabis," says Dr. Gobbi, who is also a psychiatrist at the MUHC.

Need for public initiatives

The findings highlight the importance of prevention initiatives aimed at educating teenagers on the risks associated with cannabis use while teaching them skills to resist peer pressure.

"It is clear that a lot of young people consuming cannabis are at risk of developing depression and suicidal behaviour, so it is very important for authorities to be more proactive in campaigning for prevention," states Dr. Gobbi. "We hope the findings will spur public health organizations to apply preventative strategies to reduce the use of cannabis among youth."


The combination of good self-help information and working with an experienced anxiety disorder therapist is the most effective way to address anxiety disorder and its many symptoms. Until the core causes of anxiety are addressed - the underlying factors that motivate apprehensive behavior - a struggle with anxiety disorder can return again and again. Identifying and successfully addressing anxiety's underlying factors is the best way to overcome problematic anxiety.
