Data from national surveys reveal a disturbing trend for 50- to 59-year-olds: the number of those reporting past-month abuse of illicit drugs — including the nonmedical use of prescription drugs — more than doubled from 2002 to 2010, going from 907,000 to 2,375,000, or from 2.7 to 5.8 percent in this population. Among those 65 and older, 414,000 used illicit drugs in 2010. A new topic, Prescription and Illicit Drug Abuse, available on NIHSeniorHealth.gov, describes this trend and the effects of medication and drug abuse on older adults.
