Marijuana produces euphoria, sedation, and hallucinations. The effects of these may be one or more of the following: euphoria and relaxation; gaiety and a heightened sense of the humorous; increased sensitivity and smell; increased apetite and ability to appreciate the flavor of food; and distortion of time perception---which are usually considered pleasant. The unfavorable things that may be experienced are as follows: impairment of short-term memory; decreased capacity to perform multistep task; impairment of driving skills; temporal disintegration (cannot distinguish from past, present, or future); depersonalization; decreased ability to perceive the emotions of others; and reduced interpersonal interaction.
