American College of Physicians Issues New Guidance on Cannabis for Chronic Pain

Clinical GuidelineModerate evidence
The takeaway

The ACP advises clinicians to discuss cannabis benefits and harms with chronic pain patients, while warning against use in youth, pregnant patients, those with substance use disorders, and recommending against inhaled forms.

Patients with chronic pain considering cannabis, clinicians counseling patients about cannabis options

Advises against inhaled cannabis for all chronic pain patients

What the researchers found

The ACP developed best practice advice based on systematic reviews, recommending clinicians counsel patients about cannabis for chronic noncancer pain while identifying specific subgroups where harms likely outweigh benefits: young adults and adolescents, patients with substance use disorders, those with serious mental illness, and frail patients at risk for falls.

Why it matters

This represents one of the first major U.S. medical society guidelines specifically addressing cannabis for chronic pain. Rather than a blanket endorsement or rejection, it takes a nuanced position that acknowledges potential benefits while drawing clear lines around higher-risk populations.

The numbers in context

The guidance identifies four subgroups where harms likely outweigh benefits and advises against inhaled cannabis across all patient groups.

How the study worked

Clinical guidance developed by the ACP Population Health and Medical Science Committee based on living systematic reviews and primary studies on cannabis and cannabinoid treatments for chronic noncancer pain.

What this study cannot tell us

Best practice advice is based on available evidence, which remains limited in quality and quantity. The guidance acknowledges uncertainty in many areas and relies on systematic reviews that may not capture the full range of cannabis products and formulations patients actually use.

How to read the evidence

Clinical guidance from a major medical society based on systematic review evidence, though underlying studies are often limited in quality.

The bigger picture

As cannabis legalization expands, clinicians increasingly face questions about its role in pain management. Having guidance from a major medical society gives practitioners a framework for these conversations rather than relying on anecdotal evidence or patient self-direction.

Questions still open

  • How will this guidance affect prescribing patterns in states with legal cannabis?
  • What specific cannabis formulations and doses show the most favorable risk-benefit profiles for chronic pain?

Common questions

What does the ACP recommend about cannabis for chronic pain?
The ACP advises clinicians to discuss benefits and harms with patients, while warning against use in youth, pregnant patients, those with substance use disorders or serious mental illness, and frail patients. They also recommend against inhaled cannabis for all pain patients.
Who should avoid using cannabis for chronic pain according to this guidance?
The ACP identifies four higher-risk groups: young adults and adolescents, patients with current or past substance use disorder, patients with serious mental illness, and frail patients or those at risk for falling. They also advise against use in pregnant or breastfeeding patients.
