The Nevada State Athletic Commission (NSAC) today issued the results of the drug tests performed prior to UFC 86: "Jackson vs. Griffin" at the Mandalay Bay Events Center on July 5, revealing that all eight fighters who were screened for banned substances tested negative.

Forrest Griffin, Quinton Jackson, Melvin Guillard, Justin Buchholtz, Cole Miller, Gabriel Gonzaga, Joe Stevenson and Patrick Cote were all among the fighters who were randomly selected to provide samples before their fights.

The tests are designed to deter fighters from ingesting performance enhancing drugs such as steroids and stimulants, as well drugs of abuse like marijuana, heroin, etc.

NSAC has adopted a new year-round drug-testing policy, which is perhaps the strictest of its kind in the sport.

In fact, the NSAC also tested Griffin and Jackson weeks out from the pay-per-view (PPV) event to ensure that fighters don’t "cycle" off of substances prior to their tests.

The tests were random — there was no other reason the fighters mentioned above were singled out.

However, Guillard has tested positive for cocaine in the past and Keith Kizer, NSAC executive director, has mentioned that previous failed tests will be a factor (among others) when it comes to deciding if a fighter should or should not be tested.
