Equine Research on the Short-Term Effects of Cannabidiol for the Treatment of Chronic Pain

Dated: January 1, 2020 - John Hopkins University


1. The purpose of this study was to measure the effects of CBD increase movement and promote calmness in horses. CBD was studied in horses after the administration of two oral doses (50 mg each) each day over a two-week timeframe. Forty-one horses were studied across the United States and participants were obtained through relationships with horse shelters, rescues, farms with retired show and racehorses, and general pleasure horse farms. In all of the cases, the horses were evaluated and determined, at the outset, to have impaired movement & presentation and/or demonstrated common vices of anxiety-like cribbing, pacing or reluctance to load to trailers or gates.


2. Forty-one (41) horses with clinical evidence of osteoarthritis or other chronic pain as a result of musculoskeletal injuries were selected. The majority of patients enrolled were not currently receiving treatment for their osteoarthritis or injuries. Participating horses received the cannabidiol product at an approximate dose of 1 mg CBD/10 kg of body weight, with a select group receiving 1 mg CBD/5 kg of body weight, twice daily for 2 consecutive weeks. Horse owners or caregivers were asked to use a specifically designed inventory questionnaire to assess pain in the animals receiving CBD.


3. Statistical Results Totals Counts Percent Data Reported:

  • Overall Results- 41 Horses total

  • Horses Improved 29- 71%

  • Horses Remained 10- 24%

  • Horses Regressed 2- 5%

By Condition- Anxiety - 9 Horses total

  • Horses Improved 2- 22%

  • Horses Remained 6-67%

  • Horses Regressed 1-11%

By Condition- Pain - 32 Horses total

  • Horses Improved 27- 84%

  • Horses Remained 4-13%

  • Horses Regressed 1- 3%

4. Author’s conclusion for pain management: Although the treatment protocol for the control group is not clear, there is a statistically significant improvement in the CBD treatment groups. This report attempted to find evidence for a causal relationship between use of CBD and pain management and anxiety support in horses. Based on the data gathered these conclusions were made: There is significant evidence of an association of CBD with an improvement in health and a reduction of pain observed in horses.
