Heroin addiction is a complicated medical and psychiatric issue, with well-established as well as newer modes of treatment. The case of Ms W, a 50-year-old woman with a long history of opiate addiction who has been treated successfully with methadone for 9 years and who now would like to consider newer alternatives, illustrates the complex issues of heroin addiction. The treatment of heroin addiction as a chronic disease is reviewed, including social, medical, and cultural issues and pharmacologic treatment with methadone and the more experimental medication options of buprenorphine and naltrexone.Dr Ship: Ms W is a 50-year-old woman being treated with methadone maintenance. She lives in Boston and has Medicare.Ms W began using heroin at age 14 years. She used intravenous heroin but has subsequently sniffed it as well. Friends of hers used the drug and she decided to try it. Initially she did not like it, but she returned to it for reasons she cannot understand and became addicted. She supported her habit with stealing, armed robbery, and prostitution. She has been in detoxification "more than 20 times" and had repeated difficulties remaining free from heroin use. She finds that at times of stress it is very difficult to refrain from using heroin, and she relapses.Ms W currently receives maintenance methadone, 108 mg/d. She gets her methadone once a week and sees a counselor as well. She has tried to reduce her methadone dose several times unsuccessfully. Each time, she found herself returning to heroin use. She is tired of taking methadone and would like to try buprenorphine. She hopes that this would prevent her from getting the desperate feeling she has occasionally for heroin and allow her eventually to be drug free.Ms W has 2 living children and 5 grandchildren. She lost 1 teenaged daughter to a gunshot wound. Ms W completed 10th grade and acquired her GED (General Education
