We all know rapper Wiz Khalifa likes his joints and so it didn’t really seem that odd when he sparked one up while on the red carpet of the Billboard Music Awards on Sunday.

A sneaky Las Vegas police officer managed to spot him and gave him a verbal warning. According to professional photographer Jeff Kravitz, the cop told Wiz, “Do not light that in my face again or we will take a ride downtown.”

“Could you put the weed out sir”? Yes of course. A photo posted by Wiz Khalifa (@mistercap) on May 19, 2015 at 11:30am PDT

Wiz complied and was not taken into custody.
