3 days ago · Lifetime cannabis use is associated with several aspects of brain structure and function in later life but cannabis use may not be the cause of these changes, according to a new study by researchers at Oxford Population Health and the Department of Psychiatry. Published in BMJ Mental Health, this is the largest observational study of ...

Recent research published in The American Journal of Psychiatryclosely followed nearly 1,000 individuals in New Zealand from age 3 to age 45 to understand the impact of cannabis use on brain function. The research team discovered that individuals who used cannabis long-term (for several years or more) and heavily (at least weekly, though a majority...
The new research is just one of several studies suggesting there is a link between long-term heavy cannabis use and cognition. Still, future studies are needed to establish causation and explore how long-term cannabis use might impact the risk of developing dementia, since midlife cognitive impairment is associated with higher rates of dementia.
Some people who consume cannabis long-term may develop brain fog, lowered motivation, difficulty with learning, or difficulty with attention. Symptoms are typically reversible, though using products with higher THC content may increase risk of developing cognitive symptoms. Consider the following if you are experiencing cannabis-related cognitive s...

Background Cannabis use during adolescence and young adulthood has been associated with brain harm, yet despite a rapid increase in cannabis use among older adults in the past decade, the impact on brain health in this population remains understudied. Objective To explore observational and genetic associations between cannabis use and brain structure and function. Methods We examined 3641 ...
Jun 1, 2023 · The latest findings are shedding light on how biological brain differences may influence cognitive effects in adolescent users, how cannabis can interfere with pharmaceutical medications for depression and other mental health issues, and the potential mental benefits for older adults.
Jul 16, 2020 · While there is increasing evidence that cannabis intoxication negatively affects basal cognitive functions like episodic memory, attentional control, and motor inhibition, results on the long-term effects of heavy cannabis use, and potential recovery after abstinence, remain equivocal for most cognitive domains.
