The Effects of Cannabinoid 1 Receptor on Memory

A Meta-Analysis and Systematic Review Across Species

In Summary

A recent review has exposed the contrasting information found in human and mouse model studies that study cannabis-based medicines. Acute THC use impairs non-spatial memory in humans and monkeys but not in rodents. Previous research has shown that chronic cannabis use is correlated with lower cognitive function but a mechanism of action for the decline in cognitive function has yet to be identified, and several studies have pointed that the decline is short-lived, perhaps caused by acute intoxication. This study provides evidence for cannabis-based clinical trials due to THC’s species-specific effects on memory. More information is needed to examine the full effect of cannabis on human memory as animal models have now been proven to be inaccurate.
