THC + CBD and Memory Study
RandomizedCrossoverQuadruple-blindOther
Summary
Memory deficits are one of the most consistently observed cognitive effects of marijuana use. There is evidence that some decrements attributable to the primary psychoactive ingredient, delta-9-tetrahydrocannabinol (THC), may be attenuated by cannabidiol (CBD). This study will help us learn more about the relationship between THC and CBD consumption with memory processes. A combination of MRI and neuropsychological tests (which are computer and paper/pencil tasks) will be used to measure the neurocognitive and behavioral impacts of THC and CBD use.
