What Researchers Studied About Chronic Pain and Cannabis

With opioid overdoses now the leading cause of accidental death in America, researchers wanted to know: Can medical cannabis help people reduce their reliance on dangerous painkillers?

They surveyed nearly 3,000 medical cannabis patients to understand how cannabis affects their use of opioid medications like OxyContin, Vicodin, and Percocet.

This matters because finding safer alternatives to opioids could save thousands of lives each year while still providing effective pain relief to patients who need it.

How This Survey Study Was Conducted

Researchers partnered with HelloMD, a medical cannabis platform, to survey their patients. They asked about:

• Current and past opioid use • How cannabis compared to opioids for pain relief • Whether cannabis helped them cut back on opioids • Side effects from each treatment

The survey collected responses from 2,897 medical cannabis patients, with 34% reporting they had used opioid painkillers in the past 6 months.

Chronic Pain Treatment Results

The Main Results:

  • 197% of patients agreed or strongly agreed that cannabis helped them decrease the amount of opioids they use
  • 292% of patients preferred cannabis over opioids for pain management
  • 393% said they would choose cannabis over opioids if both were equally available
  • 4Patients reported significantly fewer side effects from cannabis than from opioids
  • 581% agreed that using cannabis alone was more effective than using cannabis with opioids

What This Means for Chronic Pain Patients

If you're currently using opioid painkillers for chronic pain, this study suggests cannabis might help you:

• Reduce your opioid dose (with your doctor's guidance) • Experience fewer side effects • Maintain similar or better pain relief • Improve your overall quality of life

Important: Don't stop or reduce opioids on your own. Work with your doctor to develop a plan that might include medical cannabis as part of a comprehensive pain management strategy.

If you're concerned about opioid dependence or want to explore alternatives, medical cannabis may be worth discussing with your healthcare provider.

Quick Answers: Chronic Pain and Cannabis

Research Summary: Answers are based on published peer-reviewed studies and represent research findings, not medical recommendations. Individual results may vary. Always consult a healthcare provider before making treatment decisions.

Can I use weed instead of opioids for pain?

Yes, research suggests cannabis may help reduce opioid use. A 2017 survey of 2,897 patients found that 97% were able to reduce their opioid use after adding medical marijuana, with most reporting fewer side effects (Reiman et al., Cannabis and Cannabinoid Research).

Is marijuana better than painkillers for chronic pain?

Yes, patients report preferring marijuana. In a 2017 survey of nearly 3,000 patients, 92% preferred marijuana over opioids for chronic pain, citing fewer side effects and better quality of life (Reiman et al.).

Can weed replace my pain medication?

Possibly, with medical supervision. A 2017 study of 2,897 patients found 81% of medical marijuana users considered cannabis alone more effective than cannabis with opioids, suggesting potential for replacement of opioid pain medications.

Important Limitations

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

  • Self-selected sample: These were people already using medical cannabis, so they may be biased toward it
  • Self-reported data: Patients reported their own experiences, which wasn't verified medically
  • No control group: There was no comparison to patients who didn't use cannabis
  • Doesn't prove causation: We can't say cannabis definitely caused the opioid reduction—other factors may be involved
  • Survey design: Online surveys have inherent limitations compared to clinical trials

The Bottom Line on Cannabis for Chronic Pain

While this wasn't a clinical trial, nearly 3,000 patients reported that cannabis helped them use fewer opioids with better quality of life. For chronic pain patients concerned about opioid dependence, medical cannabis may be worth discussing with your doctor. The overwhelming patient preference for cannabis over opioids—combined with the favorable side effect profile—suggests this is an area deserving of more rigorous clinical research.

FAQs: Cannabis for Chronic Pain

What did the 2017 study find about cannabis and opioid use?

Yes, 97% of patients reported being able to decrease opioid use. A 2017 survey of 2,897 medical cannabis patients found that 97% agreed they were able to decrease opioids when also using cannabis, with 92% preferring cannabis over opioids for pain management.

Can I stop taking opioids and switch to cannabis?

No, never stop opioids without medical supervision. While this study suggests cannabis may help some patients reduce opioid use, any changes to your pain management regimen should be done under medical supervision to avoid withdrawal and ensure safe, effective pain control.

Is cannabis safer than opioids for pain management?

It may be for some patients. In this survey, patients reported fewer side effects from cannabis than from opioids. Cannabis has a lower risk of fatal overdose than opioids, but individual responses vary. Discuss the risks and benefits with your healthcare provider.

Does this study prove cannabis is effective for pain?

Not definitively. This study shows patient-reported experiences, not clinical effectiveness. While 97% of patients reported benefits, this was a self-selected survey without a control group. More rigorous clinical trials are needed.

Where can I get medical cannabis for chronic pain?

Yes, chronic pain qualifies in most states. Chronic pain is a qualifying condition for medical marijuana in most states with medical cannabis programs. MMJ.com can connect you with licensed physicians who can evaluate whether medical cannabis is right for your situation.
