Heavy cannabis use may have lasting impacts on cognitive processing, particularly working memory, even after cessation, according to a study published in JAMA Network Open. The research suggests that users may benefit from periods of abstinence before mentally demanding tasks.
Key Points
Heavy cannabis use may lead to lower brain activation during working memory tasks
Short-term effects of cannabis use were observed on memory and movement tasks
Men showed more pronounced effects than women in movement-related brain activity under the influence of cannabis
Pros
Provides valuable insights into the long-term effects of heavy cannabis use on brain function
Empowers individuals to make informed decisions about cannabis use
Cons
Does not definitively prove causation between cannabis use and observed differences in brain function
Focused on young adults, so findings may not apply to other age groups
Lacked detailed information on timing of heavy cannabis use and consumption methods
