Ah, the old “not my grinder” alibi. The rapper known as 2 Chainz was found not guilty Wednesday on the marijuana charges he picked up when his tour van was caught speeding on Maryland’s Eastern Shore.

The February arrest — which caused even more of a stir after the star posted photos on Twitter of himself posing with smiling state troopers — came after officers caught a whiff of something and found a metal grinder with some marijuana in a duffel bag, reports the Star-Democrat. But in Talbot County District Court, a security guard working for Chainz (okay, yes, he has a real name: Tauheed Epps) testified that he had packed the bag into the van, without realizing what it contained, while helping rapper and his entourage clear out of a Baltimore hotel room — and the judge agreed that he could not prove that the star owned the grinder.
