Poorer subjective sleep quality and greater pain interference are associated with intention to initiate medical cannabis among older adults with chronic pain
In a prospective cohort of 218 older adults with chronic non-cancer pain, 45% intended to start medical cannabis. Lower subjective sleep quality and higher pain interference were the strongest correlates of intention, with each unit decrease in sleep quality associated with a 69% increase in odds (ORa=1.69, CI [1.125, 2.604]) and each 10-unit increase in pain interference associated with a 13% increase in odds (ORa=1.13, CI [1.001, 1.283]).

Poorer subjective sleep quality and greater pain interference are associated with intention to initiate medical cannabis among older adults with chronic pain The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).
The Claim
Poorer subjective sleep quality and greater pain interference are associated with intention to initiate medical cannabis among older adults with chronic pain
This conclusion is most relevant to: Older adults with chronic non-cancer pain (mean age 64, SD=9; 65.1% female; 75.7% white).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Baseline Factors Associated with Intention to Initiate Medical Cannabis among Older Adults with Chronic Pain in a Prospective Cohort. (Medical cannabis and cannabinoids, 2026) —
How It Works
The proposed biological pathway:
- ▸Older adults with chronic pain experience poor sleep and high pain interference
- ▸These factors may motivate seeking alternative treatments like medical cannabis
- ▸Intention to initiate medical cannabis is higher in those with poorer sleep and greater pain interference
- ▸Result: Sleep quality and pain interference are key correlates of intention to start MC
Who Might Benefit
Evidence fit by population:
- ▸Older adults with chronic non-cancer pain (mean age 64, SD=9; 65.1% female; 75.7% white)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional baseline analysis cannot establish causality
- ▸Self-reported intention may not translate to actual initiation
- ▸Sample was predominantly white and female, limiting generalizability
- ▸Small effect sizes for group differences
Frequently Asked Questions
What factors are associated with intention to start medical cannabis in older adults with chronic pain?▼
Lower subjective sleep quality and higher pain interference are the strongest correlates, with each unit decrease in sleep quality increasing odds by 69% and each 10-unit increase in pain interference increasing odds by 13%.
Did demographic factors like age or income affect intention to start medical cannabis?▼
No significant differences were found in sociodemographic factors, comorbidity burden, polypharmacy, opioid use, or other pain treatment utilization between those who intended and those who did not intend to start MC, though higher income showed a trend.
What was the prevalence of intention to start medical cannabis in this study?▼
45% of the 218 older adults with chronic pain reported intention to start medical cannabis.
Why is sleep quality important in evaluating medical cannabis effects?▼
Poorer sleep quality is associated with intention to start MC and also affects health outcomes, so it should be considered when comparing MC users with non-users in research and clinical practice.
