Document Summary

Pharmacy: the art of compounding drugs from various substances. Substance abuse: a maladaptive pattern of using any substance that persists despite adverse social, psychological, or medical consequences. The pattern may be intermittent, with or without tolerance and physical dependence. Physical dependence: the result of physiological adaptation that occurs in response to the frequent presence of a drug; typically associated with tolerance and withdrawal. Substance dependence: a cluster of cognitive, behavioural, and physiological symptoms that occur in someone who continues to use a substance despite suffering significant substance-related problems, leading to considerable impairment or distress; also known as addiction. Tolerance: lower sensitivity to a drug so that a given dose no longer exerts the usual effect and larger doses are needed. Withdrawal: physical and psychological symptoms that follow the interrupted use of a drug on which a user is physically dependent; symptoms may be mild or life threatening.
