A new analysis highlights a growing public-health question for aging adults who use cannabis. Among people 65 and older who reported any use in the past year, more than one in nine met diagnostic criteria for cannabis use disorder (CUD).
The findings, reported by mg Magazine – Premier B2B Cannabis Magazine | Trusted Cannabis News, summarize peer-reviewed research from the University of California San Diego School of Medicine published on September 28, 2026, in the journal Addiction. The study analyzed nationally representative data from the 2021–2024 National Survey on Drug Use and Health (NSDUH) and included 21,189 adults age 65 and older.
What does “one in nine” mean for older cannabis users?
It means that among adults 65+ who used cannabis in the last 12 months, 11.4% met DSM-5 criteria for CUD. Most of these cases were mild, with smaller proportions moderate or severe.
Researchers reported that 76% of identified CUD cases in this age group were mild, 20.1% were moderate, and 3.9% were severe. The most common features among those meeting criteria were spending a great deal of time obtaining, using, or recovering from cannabis, craving, and tolerance.
How was the study conducted and who was included?
The team analyzed 2021–2024 NSDUH data, a nationally representative U.S. survey, focusing on 21,189 adults aged 65 and older. The sample reflects older Americans living in the community.
Within that population, an estimated 8.9% reported using cannabis in the prior year. Among these past-year users, 11.4% met DSM-5 criteria for CUD. The study’s lead author emphasized that any psychoactive substance—including cannabis—can lead to harmful patterns of use in older adults.

Scientific Evidence and Research Findings
Among older adults with CUD in this analysis, frequently reported diagnostic features included spending substantial time related to cannabis (74.4%), craving (67.5%), and tolerance (48.3%). These reflect DSM-5 domains that capture impairment and problematic use patterns.
Mode of use mattered in this population. Smoking was the most common route among older users in the past year (65.8%), followed by eating or drinking cannabis products (40.5%) and vaping (15.4%). Smoking was strongly associated with CUD in this age group as reported by the study.
Use frequency was a key signal. Those who used cannabis on at least 300 days in the past year were nearly four times more likely to meet CUD criteria than less frequent users. CUD was also more common among older adults reporting past-year mental illness, tobacco use, or use of drugs other than cannabis.
About one in five older users (19.9%) said a clinician had recommended some or all of their cannabis use. The authors noted that most CUD cases were mild, which suggests an opportunity for early identification and supportive interventions within routine care.
Background risks in older adults include age-related physiological changes, higher rates of chronic diseases, and frequent use of prescription medications. Prior research cited in the study has linked older-adult cannabis use with elevated risks for chronic diseases, cognitive impairment, falls, cannabis poisoning, and cannabis-related emergency care visits.
How do clinicians identify cannabis use disorder in seniors?
Clinicians use DSM-5 criteria, focusing on functional impairment and problematic patterns of use. In this study’s older cohort, time spent on cannabis, craving, and tolerance were the most commonly reported features.
The DSM-5 framework categorizes severity by the number of criteria met over a 12-month period. While the full diagnostic list extends beyond what is reported here, the study’s patterns point to domains that clinicians can explore during brief screenings and follow-up conversations.
Medical Applications and Patient Benefits
The authors acknowledged widespread interest in whether cannabis may help common chronic symptoms experienced by older adults. That interest coexists with concerns about acute adverse effects in this population and the potential for unhealthy use patterns.
If you are using cannabis for symptom relief, consider structured conversations with your care team about goals, product types, and how you plan to evaluate benefit versus risk over time. Discuss THC and CBD content, dosing plans, and preferred delivery methods such as edibles, pre-rolls, or vaping, and how those might interact with existing conditions or medications.
For homebound patients or caregivers, patient delivery services can simplify access to consistent products. If you rely on medical marijuana delivery, align refill timing with clinical check-ins so effects and side effects are reviewed systematically rather than ad hoc.
Safety Considerations and Side Effects
Age-related changes, multiple chronic conditions, and polypharmacy may amplify cannabis risks in older adults. The study references prior research connecting older-adult cannabis use with cognitive impairment, falls, cannabis poisoning, and cannabis-related emergency visits.
Discuss mental health history, tobacco use, and any other substance use with your clinician because CUD was more common with these factors in the study’s older cohort. If you smoke cannabis, consider that smoking was strongly associated with CUD in this analysis, and talk with your clinician about whether a non-inhaled route may better support your goals.
For those using edibles, start with conservative dosing plans and avoid stacking doses before onset is clear. Keep all products locked away from children and pets, label them clearly, and store them separately from other sweets to prevent accidental ingestion.
What this means for DC, Maryland and Virginia
This study provides national data and does not include DC-, Maryland-, or Virginia-specific findings. For older adults in the DMV, the practical takeaway is to proactively discuss any cannabis use with your primary care or specialty clinicians and request screening for unhealthy use.
Maryland residents and medical patients can bring these findings to appointments when making plans about product forms, dosing approaches, and whether to use md dispensaries or medical marijuana delivery. Virginia residents and caregivers can similarly plan check-ins when changing THC delivery methods or considering non-inhaled options.
In DC, if you rely on cannabis delivery or prefer pre-rolls and concentrates, share that information with your care team. Regardless of jurisdiction, ask how to monitor for early signs of problematic use and how often to reassess.
Bud Lords Take
Our read: The headline figure—11.4% of older past-year users meeting CUD criteria—underscores the importance of normalizing screening in primary care and geriatrics. Most cases were mild, so brief interventions and routine follow-up could make a real difference without stigmatizing use.
We also note the association with smoking and very frequent use. For older adults experimenting with cannabis, shifting to planned, lower-frequency use and revisiting delivery methods may help align outcomes with goals while keeping risk in view. Building care plans around what and how you actually use—pre-rolls, edibles, or vapes—beats guesswork.
How should Maryland and Virginia patients respond to these findings?
The study is national and does not provide state-specific guidance. Older adults and caregivers in Maryland and Virginia can use these results to prompt clinician conversations about screening, dosing plans, and safe storage.
When using patient delivery services, schedule deliveries to coincide with planned check-ins. If your routine involves vaping or smoking, discuss whether an edible or other non-inhaled option could reduce personal risk while meeting your needs.
What are early signs of cannabis use disorder in seniors?
Based on this study’s findings, spending a lot of time obtaining, using, or recovering from cannabis, experiencing strong cravings, and noticing tolerance are common features among older adults who met CUD criteria. If these apply, talk with a clinician.
Do certain cannabis delivery methods carry higher CUD risk?
The study reports that smoking was strongly associated with CUD in older adults. Discuss your personal risks and alternatives with your clinician if you primarily smoke.
How often is “too often” for older users?
The study found that using cannabis on 300 or more days in a year was associated with a much higher likelihood of meeting CUD criteria than less frequent use. If your use approaches daily patterns, consider a health check-in.
Can doctors recommend cannabis to older adults?
About one in five older adults who used cannabis in the past year reported that a doctor recommended some or all of their use. If you are considering cannabis, ask your clinician how to monitor effects and minimize risks.
What about CBD delivery dosage for seniors?
The study does not provide dosing guidance. Discuss CBD and THC content, delivery method, and timing with your clinician so your plan reflects your health status and medications.
Resources for further medical consultation
Bring these study results to your primary care visit and request screening for unhealthy cannabis use. Ask about interactions with current medications, safe storage practices, and how to adjust delivery methods like pre-rolls, edibles, or vaping as your health needs change.
