Medical Marijuana Helps Treat Suicidal Thoughts And Depression, New Study

A new study by a UK-based research group, Drug Science, suggests that medical marijuana could help treat suicidal ideation.

The researchers assessed about 4000 patients at the beginning of the study, but observational data was available for 2,112 patients at three months, and 777 patients for 12 months. The goal of the study was to observe the prevalence and correlates of suicidal ideation among individuals seeking medical marijuana based products, according to the paper published Wednesday in Archives of Suicide Research.

Some 25% of the sample confirmed suicidal ideation at treatment entry and were assessed to have depression and poor overall health. Their quality of life was lower and they had more trouble sleeping. Self-reported depressed mood and suicidal ideation were assessed using items from the patient health questionnaire-9.

After three months of treatment, the prevalence of suicidal ideation dropped from 23.6% to 17.6%. This means that the number of people reporting suicidal thoughts dropped by 25.4% after just three months of treatment with medical marijuana.

Furthermore, depression levels improved significantly over the year, especially for those who had suicidal thoughts at the start. Participants with suicidal thoughts, improved their depression scores by 42%, compared to 37% for those without ideation.

Differentiating Causation And Correlation

This study does not align with some of the previous findings that suggest cannabis users are more likely to have suicidal ideation. However, it could be that previous studies didn't differentiate between correlation and causation, meaning it has not been concluded if cannabis use causes suicidal thoughts, or if people with such thoughts are more prone to use cannabis.

The Drug Science study suggests that people who feel suicidal are more likely to seek medical marijuana, writes Indispensable's Hannah Harris Green. Additionally, the research suggests that once they are given access to medical marijuana, they might get relief from such symptoms.

Furthermore, previous data have shown that cannabis legalization reduces suicide rates among middle-aged males. "Critics of marijuana legalization point to studies showing correlations between heavy cannabis use and suicide, depression, and mental health disorders. However, such studies that demonstrate correlation have yet to confirm causation, which should be determined by a model's ability to predict," reads the study published in 2021.

The importance of Drug Science’s new study is primarily the conclusion that medical marijuana might be a helpful tool in treating suicidal thoughts and depression. It is also significant as it dismantles the myth, commonly used as an argument against cannabis legalization, that cannabis causes suicidal ideation.
