WIZ KHALIFA GETS OFF EASY in Infamous Jail Selfie Case

The wiz Khalifa arrest that became more famous for what happened in jail -- rather than what landed him there -- is finally over ... and he only had to pay a small fine to make it go away for good. 

Wiz pled guilty in El Paso to misdemeanor possession of drug paraphernalia and agreed to pay a $500 fine. The rapper was arrested in may 2014 for trying to get half a gram of weed past TSA officials. 

Of course, the arrest blew up on social media when wiz took a Selfie 

while behind bars ... which led to an internal investigation. Inmates on Instagram is still frowned upon there.
