Withdrawal - “Drug seeking behaviors” Diagnostic Issues - The DSM-5 term substance-related disorders include 11 symptoms that range from relatively mild (e.g., substance use results in a failure to fulfill major role obligations) to more severe (e.g., occupational or recreational activities are given up or reduced because of substance use) - Substance-related disorders and anxiety and mood disorders are highly prevalent Main Categories of Substances - Main categories - Depressants - Stimulants - Opiates - Hallucinogens - Other drugs of abuse -
