Marihuana Effects

Abstract

A study of 100 regular marihuana users indicated that marihuana use is usually a pleasant experience with few aversive effects, either during intoxication or afterwards. However, 16% reported that they "usually" experience one or more unpleasant acute or postintoxication effects, and a majority "occasionally" experience some aversive effect, including anxiety symptoms, feelings of derealization, and memory impairment.
