Document Summary

The risks include increased mortality and morbidity related to impaired driving, unsafe sexual practices, aggression, and similar concerns. The abuse of such substances has physical implications and may produce symptoms that mimic other psychopathological behaviours. Substance use disorders (suds): disorders that occur during adolescence and include substance dependence and substance abuse, which result from the self-administration of any substance that alters mood, perception, or brain functioning. Whereas almost all abused substances can lead to psychological dependence, some also extend to physical dependence. Substance dependence is also characterized as with or without physiological dependence (i. e. , with or without evidence of tolerance or withdrawal). Substance abuse: in contrast to substance dependence, this diagnosis involves one or more harmful and repeated negative consequences of substance use over the last 12 months. Because substance dependence is the more serious diagnosis, a diagnosis of substance abuse is not given if an individual meets criteria for substance dependence.
