Pharmacological Actions Central Nervous System

Marijuana produces a distinctive behavioral syndrome that is easily distinguished from that of most other drugs. The most prominent feature is the initial period of euphoria, or high, which has been described as a sense of well-being and happiness. Euphoria is frequently followed by a period of drowsiness or sedation. Perception of time is altered, along with distortions in both hearing and vision. However, illusions and hallucinations occur infrequently. The subjective effects also include dissociation of ideas.

The subjective effects of marijuana vary from individual to individual as a function of dose, route of administration, the experience and expectation of the subjects, and individual vulnerability to certain psychoactive substances. Motor coordination also may decrease, especially in situations requiring highly complex motor skills, such as flying an airplane and driving an automobile.

Increased appetite is frequently attributed to smoking marijuana. Cannabinoids are effective antiemetics, particularly in treating emesis arising during chemotherapy. A9-THC has been reported to be as effective as codeine as an analgesic, although pronounced behavioral effects occur with analgesic doses.
