Wiz Khalifa -- Busted For Weed ... Again [Update]

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.

10:19 AM PDT -- The WSPD tells us ... Wiz wasn't the only one busted for weed ... "other members of his band and staff" were cited as well.

Cops say Wiz and his people were blazing up on the tour buses BEFORE the concert. A court date has been set for July 27th.
