UPI reports the aging of the baby boom generation is resulting in a dramatic increase in levels of illicit drug use among adults 50 and older, a U.S. officials said.

Pamela S. Hyde of the Substance Abuse and Mental Health Services Administration said the increases may require the doubling of substance abuse treatment services needed for this population by 2020, according to the wire service.

UPI sayds the report, “Illicit Drug Use among Older Adults,” shows that an estimated 4.3 million adults aged 50 or older, or 4.7 percent, used an illicit drug in the past year. Less than 9 percent of men ages 50-54 had used marijuana in the past year, while 3.9 percent of women in this age group did, the report said.

Although marijuana use was more common than non-medical use of prescription drugs for adults age 50-59, among those ages 65 and older, non-medical use of prescription drugs was more common than marijuana.
