13 Alcohol –Kills over 130,000 people per year compared with 8,000 deaths from illegal drugs –Causes include genetic susceptibility, neurobiology –Treatment of alcoholism, include pharmacological interventions to reduce gravings Oxycontin: formerly known as Percodan –Crushing drug the drug allows the time released capsules to be absorbed all at once Hydrocodone (Vicodin) most widely abused prescription drug

14 HIV, AIDS, and Hepatitis C –Spreads rapidly in part due to pathogens by intravenous drug use –High-risk sexual practices resulting from lower inhibitions Behavioral Addictions: –Eating disorders –Compulsive gambling –Sexual addictions –Compulsive shopping –Tend to have the same signs and symptoms of drug addictions
