What This Study Found

Among 2,701 fibromyalgia patients, 32.4% currently used CBD and 29.4% had used it previously. Users reported improvements across multiple symptom domains, most commonly pain. About half reported minor side effects. Two-thirds disclosed CBD use to their physician but only 33% asked for physician advice.

Key Numbers

2,701 participants; 38.1% never used CBD; 29.4% past use; 32.4% current use; two-thirds disclosed to physician; only 33% sought physician advice; about half reported minor side effects

How They Did This

Cross-sectional anonymous survey of 2,701 individuals with fibromyalgia, primarily in the United States, examining CBD use patterns, reasons for use/discontinuation, physician communication, and perceived effectiveness.

Why This Research Matters

With nearly a third of fibromyalgia patients using CBD despite limited evidence, this represents a massive uncontrolled experiment. Understanding use patterns can help guide future clinical research priorities.

The Bigger Picture

The disconnect between widespread CBD use and limited clinical evidence for fibromyalgia reflects a broader pattern where consumer adoption of cannabinoid products far outpaces the research needed to guide safe use.

What This Study Doesn't Tell Us

Self-selected survey population likely overrepresents those interested in CBD, cross-sectional design, self-reported improvement without objective measures, predominantly U.S. respondents.

Questions This Raises

  • ?What distinguishes people who continue CBD use from those who stop?
  • ?Why do only a third of CBD users seek physician advice?
  • ?Would standardized CBD products show efficacy in a clinical trial for fibromyalgia?

Frequently Asked Questions

How many fibromyalgia patients use CBD?

In this survey of 2,701 patients, 32.4% currently used CBD and another 29.4% had used it in the past. Most used CBD for pain and reported at least slight improvement.

Do fibromyalgia patients discuss CBD with their doctors?

Two-thirds of CBD users disclosed their use to their physician, but only 33% actually sought physician advice on using CBD. Those not using CBD most commonly cited safety concerns as their reason.
