Wiz Khalifa — who famously raps about rolling joints “bigger than King Kong’s fingers” — was busted for weed AGAIN last night … the 2nd time in 10 days.

The Winston-Salem Police Department in North Carolina tells us … the rapper was ticketed for possession of marijuana before his concert in Winston-Salem last night.

We’re told officers discovered 11.39 grams of pot after searching the rapper and his tour bus.

Wiz was cited and released — and is required to appear in court at a later date.

As we previously reported, Wiz was caught with weed in Nashville on April 21 … after cops received complaints about marijuana smoke at a local Holiday Inn.
