The perpetually stoned Wiz Khalifa nearly had his night ruined at the Billboard Music Awards by a Las Vegas police officer. Apparently Wiz sparked up on the red carpet and was unaware of a cop in the immediate vicinity. Photographer Jeff Kravitz captured the moment and took to Facebook to share the story of the angry cop telling the rapper, “keep that shit off his carpet or he’d have to arrest him.”

Khalifa acknowledged his run in with the cop with a post on Instagram (above).

Kravitz also mused that Vegas isn’t like Los Angeles, despite medical marijuana being legal in both cities. Still, the officer was chill enough to let Khalifa continue his night with a couple of performances instead of behind bars.
