Most people with fibromyalgia who use CBD report substituting it for pain medications including opioids

Among 878 fibromyalgia patients using CBD, 72% reported substituting it for medications, most commonly NSAIDs (59%) and opioids (53.3%), with the majority reducing or stopping those medications.

What This Study Found

72% of CBD-using fibromyalgia patients substituted CBD for medications: NSAIDs (59%), opioids (53.3%), gabapentinoids (35%), and benzodiazepines (23.1%). Most reported decreasing or stopping these medications, citing fewer side effects and better symptom management. Those who substituted reported larger improvements than non-substituters.

Key Numbers

878 CBD users with fibromyalgia; 93.6% female; mean age 55.5; 72% substituted for medications; 59% for NSAIDs; 53.3% for opioids; 35% for gabapentinoids; 23.1% for benzodiazepines

How They Did This

Secondary analysis from a cross-sectional survey of 878 fibromyalgia patients currently using CBD, sub-grouped by product type (CBD isolate, hemp, CBD-cannabis, no preference) and substitution behavior.

Why This Research Matters

If fibromyalgia patients are independently substituting CBD for opioids and other medications at this scale, it signals a major unregulated shift in pain management that warrants clinical investigation.

The Bigger Picture

This widespread naturalistic medication substitution is happening without clinical evidence that CBD is effective for fibromyalgia, highlighting the gap between patient behavior and the evidence base.

What This Study Doesn't Tell Us

Self-selected sample of CBD users (likely biased toward positive experiences), no clinical verification of diagnoses or medication changes, cross-sectional design, 93.6% female and 91.5% Caucasian sample.

Questions This Raises

  • ?Is CBD actually providing therapeutic benefit for fibromyalgia or are patients experiencing placebo effects?
  • ?Are there risks to stopping opioids and gabapentinoids in favor of CBD?
  • ?Do different CBD formulations have different efficacy?

Frequently Asked Questions

Are people with fibromyalgia replacing opioids with CBD?

In this survey, yes. Among 878 fibromyalgia patients using CBD, 53.3% reported substituting it for opioids, with most decreasing or stopping opioid use. However, this was self-reported and not clinically verified.

Which CBD products were most effective?

Participants using CBD-cannabis products (containing more THC) reported significantly more medication substitutions and larger improvements in health, pain, memory, and sleep compared to those using CBD isolate or hemp products.
