title: Marijuana: a realistic approach.
abstract: Much of the current confusion concerning marijuana has been caused by a lack of definition of terms. Variations in drug effect that are related to the type and potency of cannabis preparation and route of administration need clarification. When domestic strength marijuana is smoked recreationally, the subjective effects include relaxation, mild euphoria and increased sensory awareness. The objective effects include tachycardia, reddening of the conjunctivae and a distorted sense of time. Undesirable effects such as panic reactions, amotivational behavior, and acute toxic psychosis occur infrequently and are reversible with proper therapy. Other effects which have been attributed to marijuana are unsubstantiated. The recent upsurge in use of marijuana involves persons of a different type than those who used it heretofore and has greatly increased the number of people familiar with the drug. The disparity between what many people know empirically and the information disseminated through official media has lessened the credibility of physicians with many of our younger citizens. When young people recognize misinformation about marijuana, they are no longer listening when the facts are presented about more dangerous drugs, and the abuse of these drugs must be our main concern. To be considered is the potential hazard to adolescent users who may concomitantly be exposed to a subculture of experimentation with stronger drugs at a time when the opinion of a peer group is a strong factor in their behavior.
