2 Chainz Acquitted -- Off The Hook In Marijuana Case

We saw this one coming from a mile away -- 2 Chainz has been found not guilty of weed possession ... stemming from a bust where the arresting cops took pics with the rapper.

The ruling came down in Maryland yesterday -- after a judge determined there was not enough evidence to prove the weed found in the rapper's tour van belonged to 2 Chainz.

As we previously reported, the "I'm Different" rapper was popped in February when cops pulled over a van he was riding in with six others -- though the rapper was the only one cited.

The Maryland State Police officers involved in the stop took pictures with the hip hop star ... though it was never clear who initiated the impromptu shoot, Chainz complained later on Twitter about "dam police f*ckn wit a n**ga. .... Locked me up and then Wanted pictures smh (shakin' my head)."
