Wiz Khalifa: Arrest Warrant Issued In El Paso, Texas

Wiz Khalifa -- who famously thumbed his nose at cops in El Paso by posting a jailhouse selfie -- is now a wanted man in that fair city.

Khalifa -- who was arrested in May for trying to sneak weed onto a plane at the El Paso Airport -- failed to appear in court Wednesday, so the judge issued an arrest warrant.

You may recall ... when Wiz was in the El Paso slammer he took a selfie and tweeted it out ... which triggered an investigation into jailhouse security.
