Event Summary

A new study from Washington State University, published in the Journal of Psychopharmacology, found that consuming Tetrahydrocannabinol (THC) may alter how memories form and are recalled. The research, led by Carrie Cuttler and Ryan McLaughlin, involved 120 regular Cannabis users and showed that participants who consumed Tetrahydrocannabinol were more likely to recall words never shown to them and struggled with everyday memory tasks. The study comprehensively examined multiple memory systems, revealing that acute Cannabis intoxication broadly disrupts most of them, with pronounced effects on false memory and source memory. Even moderate amounts of Tetrahydrocannabinol (20mg) showed significant interference with memory, suggesting widespread cognitive impacts.
