Fewer older adults view regular cannabis use as risky, especially those with chronic diseases
Between 2015 and 2019, the percentage of US adults 65+ who viewed regular cannabis use as risky dropped from 52.6% to 42.7%, with the steepest declines among those with chronic conditions.
Quick Facts
What This Study Found
Perceived risk of regular cannabis use decreased 18.8% overall among older adults. The sharpest drops occurred among those with kidney disease (32.1% decrease), asthma (31.7%), those who binge drink (31.3%), and never-married individuals (32.6%). People with two or more chronic conditions saw a 20.2% decrease.
Key Numbers
18,794 adults 65+. Perceived risk dropped from 52.6% (2015) to 42.7% (2019). Largest relative decreases: never married (32.6%), kidney disease (32.1%), binge drinkers (31.3%), asthma (31.7%), tobacco users (26.8%), COPD (21.5%), past-year ED use (21.0%), 2+ chronic conditions (20.2%), heart disease (16.5%).
How They Did This
Trend analysis of 18,794 adults aged 65+ from the 2015-2019 National Survey on Drug Use and Health (NSDUH), a nationally representative US survey. Examined perceived risk stratified by demographics, chronic diseases, substance use, and emergency department use.
Why This Research Matters
Older adults with chronic conditions and high-risk behaviors are showing the fastest decline in perceived cannabis risk. This is notable because these are the same populations most likely to experience drug interactions or adverse effects from cannabis use.
The Bigger Picture
Declining risk perception typically precedes rising use rates. Among seniors already managing multiple medications and chronic conditions, increased cannabis use without medical guidance could introduce new health complications.
What This Study Doesn't Tell Us
Cross-sectional survey data cannot determine causation. Self-reported perceived risk may not directly translate to behavior change. Does not capture actual cannabis use rates in this population.
Questions This Raises
- ?Is declining risk perception among chronically ill seniors translating into increased use?
- ?Are healthcare providers discussing cannabis with their older patients?
- ?What is driving the especially rapid perception shift among those with kidney disease?

What do these levels mean? →Frequently Asked Questions
Which older adults showed the biggest drop in perceived cannabis risk?
Never-married adults (32.6% relative decrease), those with kidney disease (32.1%), binge drinkers (31.3%), and those with asthma (31.7%) showed the steepest declines.
Did the majority of older adults still see cannabis as risky by 2019?
Barely. By 2019, only 42.7% of adults 65+ viewed regular cannabis use as carrying great risk, down from 52.6% in 2015. The majority no longer rated it as high-risk.
