The number of Americans aged 50+ years with a substance use disorder is projected to double from 2.8 million in 2002-2006 to 5.7 million in 2020. The authors provide a review of epidemiological findings for this understudied area of research by focusing on illicit drug use disorders and nonmedical use of prescription drugs among adults aged 50+ years. Method: MEDLINE and PsychInfo were searched using keywords drug use, drug abuse, drug misuse, substance use disorder, and prescription drug abuse. Using the related-articles link, additional articles were screened for inclusion. This review included articles published between 1990 and 2010. Result: Results from multiple sources indicated a much higher rate of illicit drug use and nonmedical use of prescription drugs and drug-related treatment admissions for persons 50 to 64 years of age compared with adults 65+ years of age. Rates of treatment admissions involving primary use of illicit and misuse of prescription drugs have increased, while rates involving primary use of alcohol only have decreased. Alcohol, opioids\/heroin, and cocaine were more likely than other substances to be associated with treatment use. Limited research data suggested the effectiveness of treatments, especially for women. Furthermore, older adults appeared to be less likely than younger adults to perceive substance use as problematic or to use treatment services. Discussion: There is robust evidence showing that an increased number of older adults will need substance abuse care in the coming decades. Increasing demands on the substance abuse treatment system will require expansion of treatment facilities and development of effective service programs to address emerging needs of the aging drug-using population.<\/jats:p>","DOI":"10.1177\/0898264310386224","type":"journal-article","created":{"date-parts":[[2010,11,18]],"date-time":"2010-11-18T00:12:27Z","timestamp":1290039147000},"page":"481-504","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":207,"title":["Illicit and Nonmedical Drug Use Among Older Adults: A Review"],"prefix":"10.1177","volume":"23","author":[{"given":"Li-Tzy","family":"Wu","sequence":"first","affiliation":[{"name":"Duke University Medical Center, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan G.","family":"Blazer","sequence":"additional","affiliation":[{"name":"Duke University Medical Center, Durham, NC, USA,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,11,17]]},"reference":[{"key":"atypb1","volume-title":"Clinical guidelines for alcohol use disorders in older adults","author":"American Geriatrics Society.","year":"2003"},{"key":"atypb2","volume-title":"Diagnostic and statistical manual of mental disorders","author":"American Psychiatric Association.","year":"2000","edition":"4"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1097\/00019442-200505000-00007"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1097\/00019442-200211000-00012"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1017\/S1041610290000308"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1097\/JGP.0b013e318190b8ef"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2009.02306.x"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1016\/S0740-5472(99)00101-4"},{"key":"atypb9","volume-title":"Health, United States, 2009: With Special Feature on Medical Technology","author":"Centers for Disease Control and Prevention.","year":"2010"},{"key":"atypb10","volume-title":"Substance Abuse among Older Adults;
