Narcotic Abuse: In 2007, the U.S. Substance Abuse and Mental Health Services reported that 21% of people over 12 years of age used prescription painkillers nonmedically. Narcotic abuse is when people use narcotics for reasons apart from the narcotic's pain-relief purpose. Signs and symptoms of narcotic abuse include euphoria, shallow breathing, small pupils, nausea, vomiting, slurred speech, confusion, and needle marks on the skin. Treatment involves addressing the long-term psychological dependence associated with narcotic abuse and administering medications such as buprenorphine, clonidine, and naltrexone to alleviate withdrawal symptoms.
