DRUGS OF ABUSE DRUGS OF ABUSE ▪ when a drug is used inconsistently with the medical or the social pattern of a culture TYPES OF DRUG DEPENDENCE: 1. PHYSICAL DEPENDENCE ▪ changes occur in the body afer repeated used of drugs that necessitates the continued administration of drug to prevent withdrawal symptoms ▪ can disappear immediately within days or weeks afer stopping the use of drugs Factors affecting the withdrawal syndrome: > The drugs being used > The dosage & the route of admission > The concurrent use of other drug > Frequency & Duration of drug use > Age, Sex, Health, & Genetic make-up of the user 2. PSYCHOLOGICAL DEPENDENCE ▪ much last longer ▪ primary reason of relapse ▪ the one that causes the addiction CLASSES OF DRUGS: 1. Narcotics 2. Stimulants 3. Depressants 4. Hallucinogens 5.
