A new study has revealed that individuals who receive hospital-based care for cannabis use disorder (CUD) face a significantly higher risk of death within five years compared to their counterparts without CUD. The elevated mortality risk was observed across all causes of death, with notable increases in suicide, trauma, opioid poisoning, other drug poisoning, and lung cancer. The study, which analyzed data from nearly 530,000 people in Ontario, Canada, highlights the serious health implications associated with untreated CUD.
Feb. 6, 2025 — People who get hospital-based care for cannabis use disorder have a 2.8-fold greater chance of dying within the next five years than people who were of the same age and otherwise had similar health factors.
The elevated risk of early death among people with cannabis use disorder applied to all causes of death, but particularly due to suicide, trauma, opioid poisoning, other drug poisoning, and lung cancer. However, the risk of early death among people with alcohol use disorder was higher among people who received hospital-based care related to the use of alcohol, stimulants, or opioids, compared to the people with cannabis use disorder.The researchers analyzed data for nearly 530,000 people living in Ontario, Canada, whose average age was 30. Among them, about 107,000 visited a hospital for care related to cannabis use disorder . During the next five years, 3.

Heavy Cannabis Use Linked to Reduced Brain Activity in Working Memory TasksA new study, the largest of its kind, reveals that heavy cannabis use is associated with reduced brain activity during working memory tasks, suggesting that the negative consequences of heavy cannabis use may be more significant than previously thought. Researchers studied around 1,000 young adults, using MRI to monitor brain activity. They found that 63% of heavy cannabis users (defined as those who had used cannabis over 1,000 times in their lifetime) demonstrated reduced brain activity during working memory tasks, leading to poorer performance. While the study cannot definitively prove causation, it highlights the potential cognitive impacts of heavy cannabis use.
