What Researchers Studied About Chronic Pain and Cannabis

With CBD products flooding the market claiming to help pain, nurses and patients need to know: Does the science actually support these claims?

This 2024 systematic review from Pain Management Nursing analyzed all available evidence on CBD specifically for chronic pain—defined as pain lasting more than 3-6 months.

By focusing on CBD (not cannabis broadly), this review helps clarify what we know about the non-psychoactive cannabinoid alone.

How This Systematic Review Was Conducted

Researchers conducted a comprehensive systematic review:

• Searched 8 databases plus gray literature through August 2022 • Followed PRISMA 2020 guidelines • Screened 1,516 articles • Included 15 studies meeting criteria • Assessed risk of bias and evidence quality using GRADE • Used narrative synthesis (couldn't do meta-analysis due to study heterogeneity)

Chronic Pain Treatment Results

The Main Results:

  • 1Most studies showed pain reduction of 42-66% with CBD or CBD+THC
  • 23 studies found no significant improvement
  • 31 study had mixed findings
  • 4Various pain measures used (VAS, verbal scales, self-report)
  • 5Evidence quality limited by heterogeneity and small number of studies
  • 6Conclusion: "CBD may be useful" but interpret with caution

What This Means for Chronic Pain Patients

This review provides a balanced picture of CBD for chronic pain:

The promising findings: • Most studies showed meaningful pain reduction (42-66%) • Both CBD alone and CBD+THC showed benefit • Suggests CBD "may be useful" for chronic pain

The reality check: • 3 studies found no benefit at all • Evidence is limited—only 15 studies met criteria • Studies used different methods, making comparison difficult

What this means for you: CBD might help your chronic pain, but it's not guaranteed. The evidence supports cautious optimism rather than certainty. If you try CBD, give it a fair trial but don't expect miracles.

For nurses and clinicians: This review suggests CBD is worth considering for chronic pain patients, especially those who haven't responded to standard treatments. But educate patients about the uncertainty in the evidence.

Does CBD oil help with pain?

Probably yes—most studies show 42-66% pain reduction with CBD. A 2024 review of 15 studies found 12 showed benefit, though 3 found no effect. Results vary by person (Gusho & Court, Pain Management Nursing).

How much does CBD reduce pain?

42-66% pain reduction in studies showing benefit. However, not everyone responds—a 2024 review found 3 out of 15 studies showed no significant improvement, so CBD doesn't work for everyone.

Will CBD help my chronic pain?

It helps most people but not everyone. A 2024 review found 12 of 15 studies showed 42-66% pain reduction with CBD. But 3 studies found no benefit—you may need to try it to know if it works for you.

Important Limitations

This study has some caveats to keep in mind when interpreting the results:

  • Only 15 studies met inclusion criteria
  • Heterogeneous study designs prevent meta-analysis
  • Different pain measures across studies
  • Many studies combined CBD with THC
  • Search ended August 2022—newer studies not included

The Bottom Line on Cannabis for Chronic Pain

This 2024 systematic review suggests CBD "may be useful" for chronic pain, with most studies showing 42-66% pain reduction. However, the evidence comes with important caveats: 3 studies found no benefit, only 15 studies qualified for review, and methodology varied widely. For chronic pain patients considering CBD, this supports it as a reasonable option to try—but expectations should be realistic, and it's not a guaranteed solution.

FAQs: Cannabis for Chronic Pain

Does CBD help chronic pain?

Probably, for some people. A 2024 systematic review found most studies show 42-66% pain reduction with CBD or CBD+THC. However, 3 out of 15 studies found no benefit, so results vary.

How effective is CBD for pain?

42-66% pain reduction in positive studies. But the evidence is mixed, not everyone responds, and the review concluded CBD "may be useful" rather than definitely works.

Is CBD or THC better for chronic pain?

Both have evidence. The review included both CBD alone and CBD+THC studies, with similar ranges of benefit. Other research suggests the combination may be more effective than either alone for some patients.
