Researchers from the Sorbonne found that among adolescents, marijuana use was linked to 46% higher odds of experiencing suicidal ideation and 85% higher odds of attempting suicide. Their research method accounted for pre-existing depression; the data they gathered shows marijuana use independently harms mental health. This comes on top of an avalanche of evidence showing that weed is connected to other severe mental health problems, including schizophrenia. What should absolutely everyone take away from this? Prevention, prevention, and prevention, especially for youth. The Sorbonne numbers suggest it’s a matter of literal life and death.
