Oldies’ dope use on a high
In just four years, marijuana use grew by 75% among adults aged 65 and older – study.
Lack of data on potential health implications worries medical profession.
In just four years, marijuana use grew by 75% among Americans aged 65 and older, according to a new study, and researchers expressed concern over a lack of information on the potential health implications.
The increase was most pronounced in women, those with higher incomes and more education, according to a report published on Monday in JAMA Internal Medicine.
The findings continue a trend seen over the last decade, said the study’s lead author, Benjamin Han, an assistant professor of geriatric medicine and palliative care at the New York University School of Medicine.
“Consider that not even 10 years ago 0.4% of adults 65 and older said they had used marijuana in the past year, and now it’s 10 times that at 4%,” Han said.
The trend is concerning, he said, because of lack of research on the effects of cannabis on older people. Some prescription and over-the-counter medicines affect older people differently, he noted.
It was not known whether the trend was tied to marijuana becoming legally available in more US states, or if people had been using the drug for many years before turning 65. Researchers initially suspected medical issues might have driven the rise in use among seniors, but most appeared to be in relatively good health,
Han said.
Researchers looked at four recent years of data from the National Survey on Drug Use and Health. Among
14 896 respondents to the nationally representative survey who were 65 or older, marijuana use increased from 2.4% to 4.2% from 2015 through 2018. In men, the percentage rose from 3.6% to 4.2%, while for women it jumped from 1.5% to 2.9%. Among college educated seniors, marijuana use over age 65 rose from 2.9% to 6.2%, and in those making $75 000 (R1 139 374) a year or more, from 2.4% to 5.5%.
The findings underscore the importance of monitoring marijuana use in this population, said Ziva Cooper, research director at the UCLA Cannabis Research Initiative, who was not involved with the study. “Without this data, we wouldn’t know what was going on in this age group,” she said. “It’s the fastest growing one and it’s important to study.”
It also points to the need for additional research. “You want to know the frequency of use, what percentage are using daily, weekly, monthly, and what are the consequences of use in this age group,” Cooper said. “Are these people newly initiating use or are they ones who were smoking marijuana in the ’60s and ’70s and are going back to it.”
