Maryland State Police spokesman Sgt. Marc Black said troopers stopped a van Thursday night about 9:15 p.m. for speeding near Easton, Md., and smelled a strong odor of burnt marijuana in the van. A backpack in the van had a marijuana grinder and trace amounts of marijuana, police said.

The rapper, whose real name is Tauheed Epps, claimed possession of the backpack and was arrested, police said. Epps was cited for having drug paraphernalia and marijuana and was released. The citation carries up to a year in jail and up to a $1,000 fine.

Agents representing Epps did not respond to requests for comment.

Last year, 2 Chainz released his solo debut, Based on a T.R.U. Story, which achieved gold status. He also has several Top 10 hits on the R&B/Hip-Hop charts as both a lead and featured artist.

After the arrest, 2 Chainz’ website tweeted a photograph that appears to show him posing with two police officers. Black said the Maryland State Police could not confirm the authenticity of the photograph but is investigating.

“Locked me up and then Wanted pictures smh,” read one tweet, using the abbreviation for shaking my head.

Epps was scheduled to perform Thursday evening at the University of Maryland Eastern Shore. His website later tweeted a photo from the stage and wrote the “show must go on.”

His manager declined to comment or confirm the tweets were from 2 Chainz himself.
