UFC 200 was thrown into a frenzy on Wednesday night when it was revealed that Jon Jones failed an out-of-competition drug test, leading to the UFC to remove him from his scheduled fight against Daniel Cormier on Saturday.
Jones’ failed test stemmed from a June 16 sample collected by USADA. The sample was taken three weeks ago and considered “out-of-competition,” which is different from in-competition. Typically in-competition samples are regarded as ones taken the day of or week leading up to a fight. The range of products that could trigger a positive sample for an in-competition drug test is much greater than out of competition tests.
USADA does not ban recreational drugs such as cocaine, heroine, marijuana etc out of competition. Nor do they ban narcotics like morphine or amphetamines like ritalin out of competition.

That means a positive test was likely triggered by something like a steroid, hormone, diuretic, IV or anything else associated with performance-enhancers.
Now why would people think cocaine when it comes to a failed drug test for Jones? He tested positive for coke a month before his last fight against Cormier in Jan. 2015 and ended up going to rehab (for a day). Some are speculating that his positive test could have been triggered by a tainted supplement.
