Record high: Study finds growing cannabis use among older adults

Older people who use marijuana today have higher income, education levels

2025-06-02
(Press-News.org) Marijuana use among older adults in the US has reached a new high, with 7 percent of adults aged 65 and over who report using it in the past month, according to an analysis led by researchers with the Center for Drug Use and HIV/HCV Research (CDUHR) at the NYU School of Global Public Health. 

Their findings, published in JAMA Internal Medicine, also show that the profile of those who use cannabis has changed in recent years, with pronounced increases in use by older adults who are college-educated, married, female, and have higher incomes.

“Our study shows that cannabis use among older adults continues to increase, although there have been major shifts in use according to demographic and socioeconomic factors,” said Joseph Palamar, PhD, MPH, an associate professor of population health at NYU Grossman School of Medicine, an affiliated researcher with CDUHR, and the study’s senior author.

Most Americans live in a state where marijuana has been legalized for medical use, recreational use, or both. To better understand the prevalence of marijuana use among older adults in the US, researchers examined data from the National Survey on Drug Use and Health from 2021 through 2023. The respondents, who were 65 and older, were asked about past-month cannabis use, which was defined as “current” use.

“This is the first time we were able to examine ‘current’ use of cannabis in this age group. Before, we were only able to look at past-year use because the numbers for current use were too small,” said Benjamin Han, MD, MPH, associate professor and associate chief of research in the Division of Geriatrics, Gerontology, and Palliative Care at the University of California San Diego and the study’s first author.

The researchers found that current cannabis use among older adults grew to 7 percent in 2023, up from 4.8 percent in 2021 and 5.2 percent in 2022—a nearly 46 percent increase in only two years.

“If we look even further back to 2006 and 2007, less than 1 percent of older adults used cannabis in the past year. Now, we’re seeing that 7 percent have used it in the past month alone,” said Han, an affiliated researcher with CDUHR.

Certain groups of older adults experienced sharper increases in use over this period than others, including those who are married, white, have a college degree, and have an income of at least $75,000. Older women also saw a steep increase in cannabis use, although older men are still more likely than women to use the drug.

In addition, cannabis use grew more among those living in states where medical marijuana is legal versus states where it is not.

“It shouldn't be surprising that use is becoming increasingly more common among people who live in states that allow medical cannabis, which could be due to increased availability or social acceptability,” said Palamar. “Interestingly, with respect to income, those with the highest incomes had the lowest prevalence of cannabis use in 2021, but by 2023 this group had the highest prevalence, which may indicate who has access to medical cannabis given its costs.”

The researchers also found significant increases in cannabis use by older adults with chronic diseases—and notably, those with multiple chronic conditions—including heart issues, diabetes, hypertension, cancer, and chronic pulmonary obstructive disease.

The authors caution that the overall increases may be driven, in part, by those who use cannabis aging into the 65+ age bracket for the period studied. Regardless, they recommend that clinicians screen and educate their older patients about cannabis use, including how physiological changes that accompany aging can make people more sensitive to psychoactive substances.

“As a geriatrician, I see more and more people interested in using cannabis for treating chronic health symptoms. But cannabis can complicate the management of chronic diseases and be potentially harmful if patients are not educated on its use and potential risks,” said Han.

Kevin H. Yang of UC San Diego and Charles Cleland of NYU Grossman School of Medicine were also co-authors on the study. The research was supported by the National Institute on Drug Abuse (K23DA043651, R21DA058404, R21DA060362, R01DA057289, R01DA060207, and P30DA01104) and the UC San Diego Sam and Rose Stein Institute for Research on Aging.

Trends in past-month cannabis use among older adults

2025-06-02
About The Study: Between 2021 and 2023, prevalence of current cannabis use increased among adults age 65 or older nationally, with key demographic subgroups experiencing marked increases. Adults with the highest incomes initially had the lowest prevalence of cannabis use vs other income levels, but by 2023, they had the highest prevalence, which may indicate better access to medical cannabis given its costs.  Corresponding Author: To contact the corresponding author, Benjamin H. Han, MD, email b2han@health.ucsd.edu. To ...

How to create aqueous 100 nm-sized materials with polycavities

2025-06-02
While molecues with a single cavity have been extensively studied in solution, the solution state functions of polycavity materials remain elusive owing to their synthetic inaccessibility. Porous aromatic polymers (PAPs) are synthesized in a single step and offer polymeric cavity frameworks with high stability, which are applicable to gas and molecule adsorption/separation only in the solid state. Due to their strong aggregation-derived insoubility, unsubstituted PAPs cannot be used in any solvent until now. To move the functions of PAPs from the solid to the solution ...

Pre-operative THP leads to a pCR in two-thirds of early-stage HER2+ ER- breast cancer patients

2025-06-02
Patients with Stage II and III (early-stage) HER2+ breast cancer usually undergo pre-operative therapy with multi-agent chemotherapy in combination with anti-HER2 antibodies, followed by surgery. A less intensive, reduced chemotherapy treatment approach is currently being evaluated in the CompassHER2 pCR trial (EA1181, NCT04266249) by the ECOG-ACRIN Cancer Research Group (ECOG-ACRIN). While longer follow-up is needed to assess long-term outcomes, pathologic complete response (pCR) rates and predictors of ...

Immune system discovery reveals potential solution to Alzheimer’s

2025-06-02
A new way of thinking about Alzheimer’s disease has yielded a discovery that could be the key to stopping the cognitive decline seen in Alzheimer’s and other neurodegenerative diseases. University of Virginia School of Medicine scientists have been investigating the possibility that Alzheimer’s is caused, at least in part, by the immune system’s wayward attempts to fix DNA damage in the brain. Their research reveals that an immune molecule called STING drives the formation of the harmful plaques and protein ...
