Study Summary
The purpose of this study is to begin investigating acute impairment of various forms of memory and learning by Tetrahydrocannabinol (THC) in cannabis (CNB) compared to placebo, in a 2-session per subject double-blind, random assignment, placebo-controlled counterbalanced design in young to middle-aged adults.
Primary Outcome
CWMS Task assesses immediate plus delayed recall and working memory by assessing working memory capacity by presenting a list of stimuli to be recalled while simultaneously performing a secondary task. This task uses a fully crossed design which includes both same-domain CWMS conditions (e.g. verbal storage combined with verbal processing) as well as cross-domain CWMS conditions (e.g., verbal storage combined with spatial processing). Mean number of total items recalled.
