Cannabis and Temporal Disintegration in Experienced and Naive Subjects

Abstract

The effects of 3.3 and 6.6 milligrams of Δ⁹-tetrahydrocannabinol and of placebo on performance of three cognitive tasks were compared for naive subjects and experienced cannabis smokers. No differences in performance or reported subjective effects were found between these two groups. A significant decrement was found following dosage at both levels, replicating earlier findings of temporal disintegration during cannabis intoxication.
