In Competition vs. Out Of Competition And Why NSAC Won't Suspend Jones
There seems to be a lot of confusion about what is prohibited when, and what time periods "in-competition" and "out-of-competition" cover.
WADA maintains 2 main lists. One list has substances that are banned at all times. This includes anabolic steroids, growth hormones, masking agents, etc:

The other is for substances that are only banned in competition. Cocaine and THC are on this list.

There are other lists for individual sports (alcohol is banned in archery, for example), but that's not relevant to Jones.
Jones was tested on December 4th, a full month before his fight. The definitions for "in-competition" and "out-of-competition" are in the WADA code:

Jones' failed test was out of competition. You can compare this to people busted for THC, like Nick Diaz, Matt Riddle, and others, who failed tests administered immediately before or after their fights. You could also compare it to someone like Sonnen, who tested positive while out of competition, but for substances that were on the "at all times" list, rather than the "in competition" list. Unless the NAC has wording in their regulations that redefines the competition period to cover training camps, or that recategorizes cocaine as a substance that is banned at all times, they don't really have cause to suspend Jones for a failed test. That wasn't the case with Diaz, Riddle, Healy, and others. It isn't that cocaine is considered less serious, it's that the test he failed wasn't immediately before or after the fight, it was a month away from it.
