Marijuana and PED Statistics In MMA

I wanted to compose a statistical analysis of PED use in MMA. The data below goes back to 2001, credit to CagePotato, CombatSportsLaw ,@Dimspace and @70bpmhiccups for all the data provided.

I’ve broken the data down into separate sections. Each section has the fight outcome and percentage. Also, each section is further broken down into organizations like UFC, PRIDE and Bellator. I know there will be some debate on what should be considered a performance enhancing drug, so I tried my best to separate what I thought were legit PEDs vs Banned Substances.

For the PED and Marijuana portion I linked all the wins and losses with the news article related to that test result. The totals at the bottom come from the sources I’ve linked above.

After I spent hours going through all of this data, it was pretty shocking. I knew beforehand that the statistics didn’t support the claim for PEDs actually helping you win a fight, but I was more shocked about marijuana. Even though I don’t personally believe marijuana is a performance enhancing drug, the statistics show a different result.

10/27/2016 UPDATE: CABMMA released 7 anti-doping violations 6 days ago, these are from events held in March and May and the results were just released in October. I’ve updated the stats below accordingly.

3/17/2017 UPDATE: Three fighters at UFC FN 104 fail in-competition tests for marijuana.

4/6 UPDATE: Kelvin Gastelum is flagged by USADA for marijuana.

5/10 UPDATE: Jessica Penne is flagged by USADA

5/26 UPDATE: Cortney Casey fails drug test

9/22 UPDATE: Jon Jones fails drug test
