Cannabidiol—commonly known as CBD oil—is now classified as a Class 2 drug by the Association of Racing Commissioners International. As such, it is considered a forbidden substance by APHA and is prohibited for use in horses competing in APHA-approved events, per rule SC-085.C.1 in the APHA Rule Book.
The ARCI revision took place in January 2019. Per SC-085, drug testing can be conducted at any APHA-approved event; most notably, drug testing takes place at the APHA World Championship Shows. If found in violation of Rule SC-085, the horse owner and caretaker—among others—can be subject to disciplinary action by APHA.
From the 2019 APHA Rule Book:
SC-085 Drugs and Medications
C. FORBIDDEN SUBSTANCES. A horse shall not be shown in any class at a show approved by the APHA or event held in conjunction with an APHA-approved show, whether or not the event is approved by APHA, if the animal has been administered in any manner a forbidden substance. A forbidden substance is defined as:
D. CAUTION AGAINST MEDICINAL PREPARATIONS. The use of medicinal preparations and tonics of any kind in which the ingredients and quantitative analysis are not specially known is also cautioned against as the use of such may result in a positive analysis of the specimen taken from the horse.
