Cormier lost his light heavyweight title to Jones at UFC 214 in July, but has subsequently been reinstated as the champion after Jones tested positive for a banned substance and the bout was deemed a 'No Contest'.
No punishments have been handed out by USADA yet, other than a provincial suspension after the drug test failure was announced.
Should Jones be found guilty of knowingly taking Turanibol, he faces the prospect of being banned from competing for the next four years.
Jones' team have previously claimed that a dubious supplement is likely the cause for the positive results. "I have never felt so much love", Cormier wrote on his Instagram account on Friday.
After knocking out Cormier in the third round of UFC 214's headliner, Jones seemed to turn over a new leaf with his longtime rival.More news: Florida nursing home deaths increase Irma's toll, and raise questions
"I think it's insane", Cormier said.
"If it's a four-year thing, I think it could be just that kind of devastation (that stops Jon from coming back), and which like I said, it's not fair, you know?"
If Jones' violation is upheld, his career could be facing a death sentence.
"I can't believe we are going through all of this again", he said in a prepared statement.
This is not the first time that the fighter has been removed from his title. It's the same argument from a failed test at UFC 200, which ultimately led to a one-year suspension.
Whatever the ultimate verdict, Cormier wants his followers to respect Jones.
