Chronic pain is one of the most prevalent and costly health conditions in the United States — and one of the most undertreated. For millions of Americans who have found little relief from conventional medications, the growing body of clinical evidence supporting cannabis as a pain management tool represents a meaningful and legitimate alternative worth understanding.

At CBD Wellness, one of the first CBD brands in the United States, we present only what the science supports. The evidence on cannabis and chronic pain is among the most robust in the entire field of cannabinoid research. Here is what it shows.

The Scale of Chronic Pain in America

Chronic pain — defined as pain lasting six months or more and requiring medical intervention — affects an estimated one in five US adults. That represents tens of millions of people living with daily pain that significantly impacts their quality of life, productivity, and mental health.

The economic burden is staggering: health economists estimate the annual cost of chronic pain in the United States at $635 billion in healthcare costs and lost productivity — more than the annual costs of heart disease, cancer, and diabetes combined.

Perhaps most troubling: nearly half of chronic pain patients report that their pain persists despite the use of conventional pain medicines, including NSAIDs (non-steroidal anti-inflammatory drugs) and opioids. This treatment gap — millions of people in pain with no adequate pharmaceutical solution — is precisely why cannabis has become one of the most actively researched pain management tools of the past two decades.

The National Academies of Sciences: A Landmark Conclusion

In 2017, the National Academies of Sciences, Engineering, and Medicine published a comprehensive review of over 10,000 peer-reviewed scientific papers on cannabis and health. Their conclusion on chronic pain was unambiguous:

"In adults with chronic pain, patients who [are] treated with cannabis or cannabinoids are more likely to experience a clinically significant reduction in pain symptoms. … There is conclusive or substantial evidence that cannabis is effective for the treatment of chronic pain in adults."

"Conclusive or substantial evidence" is the highest level of confidence used in this type of scientific review. This is not a fringe finding — it is the considered conclusion of one of the most respected scientific bodies in the United States, based on the largest systematic review of cannabis research ever conducted.

Randomized Controlled Trials: The Clinical Evidence

Beyond the National Academies review, numerous randomized, placebo-controlled trials — the gold standard of clinical research — have documented the ability of cannabis to significantly reduce pain across a wide range of patient populations and conditions, including:

  • HIV-associated neuropathic pain
  • Diabetic peripheral neuropathy
  • Spinal cord injury pain
  • Severe treatment-resistant neuropathy
  • Musculoskeletal and inflammatory pain
  • Laboratory-induced pain in healthy volunteers

These results have been replicated across multiple delivery methods — including inhaled cannabis, vaporized cannabis, and plant-derived cannabis extracts — and at both standard and relatively low doses. Longitudinal data further demonstrates that cannabis provides continued pain relief over the long term without producing significant adverse side effects, including in elderly populations.

Cannabis as an Opioid-Sparing Agent

One of the most clinically significant findings in cannabis pain research is its potential to reduce opioid dependence. The opioid crisis has claimed hundreds of thousands of American lives, and finding safe, effective alternatives — or agents that allow opioid doses to be reduced — is a public health priority of the highest order.

The research on cannabis as an opioid-sparing agent is compelling:

Cannabis Enhances Opioid Efficacy

Multiple clinical studies have documented that the co-administration of cannabis with opioids augments the pain-relieving effects of opioids, potentially allowing for effective pain control at lower opioid doses with fewer side effects.

  • One study found that vaporized herbal cannabis enhanced the pain-relieving activity of both morphine and oxycodone in chronic pain subjects, with authors concluding this could allow "for opioid treatment at lower doses with fewer side effects."
  • A separate study reported similarly enhanced analgesic efficacy when low doses of oral THC were combined with hydromorphone (Dilaudid). Authors stated these data are "indicative of [the] possible opioid-sparing effects" of cannabinoids.
  • These synergistic effects have been documented even when sub-therapeutic doses of both cannabis and opioids were used — meaning neither dose alone would be sufficient, but together they produce meaningful pain relief.

Physician Consensus on Opioid Tapering

The clinical acceptance of cannabis as a pain management tool has reached a significant milestone. In 2020, a coalition of physicians issued consensus-based recommendations surrounding the safe introduction and titration of cannabinoids in concert with tapering opioids — a formal clinical framework for using cannabis to help patients reduce opioid dependence under medical supervision.

This represents a meaningful shift: cannabis is no longer being discussed only in alternative medicine circles but is being formally integrated into mainstream clinical pain management protocols.

CBD Specifically for Pain: What It Offers

While much of the opioid-sparing research involves THC, CBD (cannabidiol) — the non-psychoactive cannabinoid — has its own well-documented role in pain management, particularly for inflammation-driven pain. CBD's anti-inflammatory properties make it especially relevant for conditions like:

  • Arthritis and joint pain
  • Neuropathic pain
  • Post-surgical or injury-related inflammation
  • Chronic back and neck pain
  • Fibromyalgia

Unlike THC, CBD does not produce psychoactive effects, making it accessible for daily use without impairment. Hemp-derived CBD is also federally legal and available throughout Arizona without a medical card or dispensary visit. To understand the difference between CBD and THC, read our CBD vs THC guide.

Delivery Methods for Pain Relief

The right CBD delivery method depends on the type and location of your pain:

  • CBD salves (topicals): Best for localized pain — joint pain, muscle soreness, arthritis flare-ups. Applied directly to the skin for targeted relief within minutes. View our CBD salves.
  • CBD tinctures (oils): Best for widespread or systemic pain — neuropathy, fibromyalgia, chronic inflammation. Taken sublingually for fast absorption and full-body effect. View our CBD tinctures.
  • Hemp flower: Fastest onset for acute pain episodes. View our hemp flower.

Frequently Asked Questions: Cannabis and Chronic Pain

Is there scientific evidence that cannabis relieves chronic pain?

Yes — and it is among the strongest in cannabinoid research. A 2017 review of over 10,000 peer-reviewed studies by the National Academies of Sciences, Engineering, and Medicine concluded there is "conclusive or substantial evidence" that cannabis is effective for the treatment of chronic pain in adults. Dozens of randomized controlled trials across thousands of patients support this conclusion.

Can CBD replace opioids for pain management?

CBD and cannabis are not direct replacements for opioids, but clinical research suggests they may allow opioid doses to be reduced while maintaining effective pain control — a concept known as opioid sparing. In 2020, a coalition of physicians issued formal consensus recommendations for using cannabinoids in concert with opioid tapering. Always consult your physician before making any changes to opioid medications.

What types of chronic pain does CBD help with?

Clinical trials have documented cannabis efficacy for neuropathic pain (HIV, diabetes, spinal cord injury), inflammatory pain (arthritis, musculoskeletal conditions), and treatment-resistant pain. CBD specifically is well-studied for inflammation-driven pain including arthritis, back pain, and fibromyalgia.

What is the best CBD product for chronic pain in Arizona?

For localized pain (joints, muscles, arthritis), a CBD salve applied directly to the affected area provides targeted relief. For widespread or systemic pain (neuropathy, fibromyalgia, chronic inflammation), a CBD tincture taken sublingually provides full-body support. CBD Wellness ships both products throughout Arizona. Browse our collection.

Is CBD legal for pain relief in Arizona?

Yes. Hemp-derived CBD containing less than 0.3% THC is federally legal under the 2018 Farm Bill and fully legal in Arizona. No medical card or dispensary visit is required. CBD Wellness ships directly to customers throughout Phoenix, Scottsdale, Tucson, Tempe, Mesa, Flagstaff, and across the state.
