New Government Funded Study: Cannabis May Improve Attention and Memory

A new study published and funded by the National Institute of Health hasmarijuana2008 found that poor working memory and attention control is associated with a lower efficiency of the endocannabinoid system, indicating that cannabis could improve these functions as it activates and positively regulates this system.

“Our results suggest that.. a lower efficiency of the endocannabinoid system, probably due to a lowered expression of CB1R, produced a reduction in the performance of these subjects when attentional control and working memory processing is challenged.”

The study, which can be found by clicking here, was conducted by researchers at the Universidad Nacional Autónoma de México.

    Haven’t studies in the past indicated that cannabis exposure severely inhibits working memory and attention control? Not permanently, but rather for the duration of intoxication. I thought this was an established effect of marijuana intoxication, and as any smoker can attest, it seems to ring true.

      That is just the most well known hoax.

      THC even promotes cell growth in the part of the brain responsible for memory.
