Persons who abuse hallucinogens use them much less often than do those with Dependence. However, they may repeatedly fail to fulfill major role obligations at school, work, or home due to behavioral impairment caused by Hallucinogen Intoxication. The individual may use hallucinogens in situations in which it is physically hazardous (e.g., while driving a motorcycle or a car), and legal difficulties may arise due to behaviors that result from intoxication or possession of hallucinogens. There may be recurrent social or interpersonal problems due to the individual's behavior while intoxicated, isolated lifestyle, or arguments with significant others.
