Cannabis products with exceptionally high concentrations of THC have been associated with increased instances of depression, anxiety, and dependence.
Marijuana is the third-most commonly used drug globally, after alcohol and nicotine. Its potency, measured by the concentration of THC, has steadily increased over the past few decades, raising the risk of users experiencing psychosis and addiction, according to an analysis published in the Lancet last week that was conducted by a team of mental health experts at the University of Bath’s Department of Psychology in the United Kingdom. The psychologists analyzed the association between the types of marijuana people use and addiction and mental health issues, drawing on 20 studies involving nearly 120,000 people.
