3 days ago · Cannabis use has increased worldwide following its legalisation for medical and recreational purposes in many countries but the potential long term effects on the brain remain unclear. Previous studies have found that regular cannabis use is associated with a decline in neurocognitive abilities and has had a damaging effect on brain structure and function.
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.

As a pharmacy student at the University of Wisconsin–Madison, Natasha Mason was struck by the high volume of patients who complained about opiates and antidepressants not working, but at the same time became more and more dependent on them.
This observation triggered an interest in the behavioural effects of psychedelic drugs, which took her career in a psychopharmacological direction. She now researches the neural effects of cannabis, both when people are under the influence of the drug, and over the longer term, at Maastricht University in the Netherlands.
Mason is also interested in the positive and negative effects of developing a tolerance to cannabis.

Apr 18, 2024 · This study found that cannabis use during adolescence was associated with alterations in brain function in medial prefrontal cortical and insular brain regions during cognitive task. The study measured executive functioning, emotional reactivity and regulation, and processing of rewarding stimuli.
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 ...
The most well known are delta-9-tetrahydrocannabinol (THC), which produces a mental “high,” and cannabidiol (CBD), which doesn’t. Depending on the type of product used, cannabis can be smoked, inhaled, taken by mouth, rubbed into the skin, or mixed into food and beverages.
Dec 18, 2023 · There is growing evidence that cannabis use may disrupt adolescent brain development, but in older adults it seems to lead to more neural connections in brain regions associated with memory...
