A significant shift in the social and medical landscape of the United States is becoming increasingly visible within its aging population, as a new analysis reveals that marijuana use among older adults has reached an all-time high. According to a comprehensive study led by researchers from the Center for Drug Use and HIV/HCV Research (CDUHR) at the NYU School of Global Public Health, approximately 7 percent of adults aged 65 and older now report using cannabis within the past month. This finding, which highlights a rapid and pronounced upward trend in consumption, suggests that the traditional image of the cannabis user is being replaced by a demographic that is increasingly older, more affluent, and more educated than in previous decades.
The research, which was recently published in the prestigious journal JAMA Internal Medicine, provides a detailed look at how the profile of the American cannabis user has transformed over a remarkably short period. Beyond the mere increase in the number of seniors using the drug, the study identifies a shift in the socioeconomic and demographic characteristics of these individuals. Specifically, the data points to a sharp rise in use among older adults who are college-educated, married, and female. Furthermore, the findings indicate that those with higher household incomes are now among the most likely to report current use, a reversal of previous trends that often associated substance use with lower socioeconomic brackets.
Dr. Joseph Palamar, an associate professor of population health at the NYU Grossman School of Medicine and the study’s senior author, noted that while the overall increase in use is striking, the nuances within the demographic shifts are equally important for public health officials to understand. He emphasized that cannabis use among older adults is continuing to climb, but the internal dynamics of who is using the drug are moving in new directions. As an affiliated researcher with CDUHR, Dr. Palamar suggested that these shifts reflect broader changes in how marijuana is perceived and accessed across different layers of American society.
To arrive at these conclusions, the research team analyzed data from the National Survey on Drug Use and Health, covering the years 2021 through 2023. This period is particularly significant as it follows several years of rapid legislative change across the United States, where a majority of residents now live in jurisdictions where marijuana is legal for either medical or recreational purposes, or both. The study focused specifically on respondents aged 65 and older, asking them about their cannabis consumption habits within the thirty days prior to the survey. This "past-month" metric is defined by researchers as "current" use, providing a snapshot of regular or ongoing consumption rather than occasional or experimental use.
The ability to focus on current use marks a significant methodological advancement for researchers studying this specific age group. Dr. Benjamin Han, an associate professor and associate chief of research in the Division of Geriatrics, Gerontology, and Palliative Care at the University of California San Diego, explained that previous studies were often limited to looking at "past-year" use. This was because, in earlier years, the number of seniors reporting use within a single month was too small to provide statistically significant data. Dr. Han, who served as the study’s first author, noted that the rise in consumption has now reached a threshold where researchers can accurately track current, active users among the elderly for the first time.
The trajectory of this increase is notable for its velocity. In 2021, the prevalence of current cannabis use among adults 65 and older sat at 4.8 percent. By 2022, that figure had ticked up to 5.2 percent. However, by 2023, the rate jumped to 7 percent, representing a nearly 46 percent increase in just two years. When viewed through a longer historical lens, the change is even more dramatic. Dr. Han pointed out that as recently as 2006 and 2007, less than 1 percent of older adults had used cannabis even once in the preceding year. To go from less than 1 percent annual use to 7 percent monthly use in less than two decades represents a profound cultural and behavioral transformation among America’s seniors.
The researchers highlighted that the growth in use was not uniform across the entire senior population. Certain subgroups experienced much sharper increases than others. For instance, the data showed that white, married seniors with a college degree were among those seeing the most significant rises in consumption. Additionally, individuals with an annual income of at least $75,000 emerged as a group with a particularly steep upward trend. While older men generally remain more likely to use cannabis than older women, the study found that the gap is narrowing as older women increasingly turn to the drug.
Geography and state-level policy also appear to play a critical role in these trends. The research found that cannabis use grew more rapidly among seniors living in states where medical marijuana is legal compared to those living in states where it remains prohibited. This correlation suggests that legal frameworks do more than just provide access; they likely contribute to a reduction in the social stigma associated with the drug. Dr. Palamar observed that the increasing commonality of use in legal states is an expected outcome of both greater availability and a growing sense of social acceptability.
One of the more intriguing findings involved the relationship between income and cannabis use. In 2021, those in the highest income brackets actually had the lowest prevalence of use among the groups studied. However, by 2023, this group had surged to the highest prevalence. Dr. Palamar suggested that this might be an indicator of who can afford to navigate the often-expensive world of medical cannabis. Between the costs of physician consultations, state-mandated registration fees, and the retail price of the products themselves—which are not covered by health insurance—the financial burden of medical marijuana use may currently favor those with higher disposable incomes.
Perhaps the most significant finding from a clinical perspective is the link between cannabis use and chronic health conditions. The researchers discovered that use is increasing significantly among older adults who suffer from chronic diseases, and even more notably among those with multiple co-occurring conditions. This includes patients managing heart disease, diabetes, hypertension, cancer, and chronic obstructive pulmonary disease (COPD). The high prevalence of use among this group suggests that many seniors are likely turning to cannabis as a tool for symptom management, seeking relief from the pain, anxiety, or sleep disturbances that often accompany long-term illness.
However, this trend toward "self-medicating" or using cannabis as an adjunct to traditional medicine brings with it a set of complex risks. Dr. Han, speaking from his perspective as a geriatrician, expressed concern about the potential for cannabis to complicate the management of chronic diseases. He noted that as people age, their bodies undergo physiological changes that can alter how they process substances. These changes can make older adults more sensitive to the psychoactive effects of cannabis, potentially increasing the risk of falls, confusion, or adverse interactions with other medications.
The researchers also noted that the overall increase in use is likely influenced by a cohort effect. As the "Baby Boomer" generation ages, individuals who may have used cannabis in their youth are moving into the 65-and-older age bracket. These individuals may carry more favorable attitudes toward the drug than the generations that preceded them, contributing to the higher numbers seen in recent years. Regardless of whether the increase is driven by new users or lifelong users aging into the study group, the researchers are calling for a proactive response from the medical community.
The study authors recommend that clinicians prioritize screening and educating their older patients about cannabis use. Because many seniors may not view marijuana in the same light as prescription pharmaceuticals, they may not think to mention it to their doctors during routine visits. Dr. Han emphasized that if patients are not properly educated on the potential risks and the way cannabis interacts with their specific health profiles, the drug could prove harmful rather than helpful. He stressed the importance of open communication between patients and providers to ensure that cannabis use does not interfere with the overall goal of managing chronic health symptoms safely.
In addition to Dr. Han and Dr. Palamar, the study was co-authored by Kevin H. Yang of UC San Diego and Charles Cleland of NYU Grossman School of Medicine. The research received support from several branches of the National Institute on Drug Abuse and the UC San Diego Sam and Rose Stein Institute for Research on Aging. As the legal status of cannabis continues to evolve across the country, the findings serve as a reminder that the demographic most affected by these changes may be the one that was previously least expected. For the millions of American seniors now incorporating cannabis into their lives, the intersection of aging, health, and policy remains a critical area for ongoing medical and social scrutiny.
