Effects of Marijuana on Recall of Narrative Material and Stroop Colour-Word Performance

Nature volume 237, pages 172–173 (1972)Cite this article

Abstract

Two recent articles1,2 report that marijuana interferes with the recall of narrative material learned in either a drug or no drug state and recalled in the drug state, but the evaluation of the results is hampered by (1) the lack of specification of the Δ9-THC content of the marijuana cigarettes and (2) an absence of placebo controls. We have set out to test the effects of marijuana on narrative recall and Stroop colour-word performance and to remedy these defects of experimental design. The Stroop test was selected because performance has been shown to be impaired by depressants Such as amobarbital3 and because marijuana has barbiturate-like effects4.
