Study breakdown

Older adults are the fastest-growing group of cannabis users, but research on how it affects aging brains and hearts is just beginning

Narrative ReviewModerate evidence
The takeaway

A narrative review found that most older adults who use cannabis do so for medical purposes like pain and insomnia, but cardiovascular risks, cognitive effects during aging, and potential for treating neurodegeneration remain poorly studied.

Older adults using or considering cannabis, geriatricians, and researchers studying cannabis effects across the lifespan.

Fastest-growing demographic of cannabis users; most for medical purposes

What the researchers found

Most older adults who use cannabis report doing so for medical purposes, primarily targeting pain, insomnia, anxiety, and depression. Many do not discuss cannabis use with their medical providers. Emerging evidence from younger populations suggests cardiovascular risks of heavy use, but this has not been thoroughly studied in aging adults.

Why it matters

The older adult population is growing and using cannabis at increasing rates, yet clinical trials and safety data are almost entirely from younger populations. Age-related changes in metabolism, cardiovascular health, and cognition create unique risk profiles.

The numbers in context

Most older adult cannabis users report medical purposes. Common targets: pain, insomnia, anxiety, depression. Many do not discuss use with providers. Cardiovascular risks documented in younger populations but unstudied in seniors.

How the study worked

Narrative review synthesizing current literature on cannabis use trends, health considerations, and preclinical models relevant to older adult populations.

What this study cannot tell us

Narrative review without systematic methodology. Limited evidence base specific to older adults. Most existing data extrapolated from younger populations.

How to read the evidence

Moderate: narrative review identifying important knowledge gaps with limited direct evidence from older adult populations.

When this study was published

Published 2026.

The bigger picture

Cannabis sits in an interesting tension for older adults: it may help with common aging complaints (pain, sleep, appetite) while also carrying understudied risks for the cardiovascular and cognitive systems most vulnerable to aging.

Questions still open

  • Does cannabis accelerate or slow cognitive decline in aging? How do age-related changes in metabolism affect cannabis safety and dosing? Why are many older adults not discussing cannabis use with their providers?

Common questions

Is cannabis safe for older adults?
The evidence is incomplete. Most cannabis safety data comes from younger populations, and age-related changes in cardiovascular health and cognition may create different risk profiles that need dedicated research.
Why do older adults use cannabis?
Most report medical purposes, particularly for pain, insomnia, anxiety, and depression. Many do not discuss their use with healthcare providers.
