If has-been rapper Bobby Brown wants to do a few lines of cocaine — that’s his prerogative. And the courts seem to agree.

Whitney Houston’s ex-hubby Brown will not face criminal charges after police said they found a small amount of cocaine in his possession. A Brockton District Court clerk magistrate found no probable cause to issue a criminal complaint, but recommended that Brown volunteer to mentor young people.

Brown agreed to a year’s community service and his attorney said if no other issues arise over the next year, the matter will be struck from the docket.

The rapper’s trouble all started when police responding to a disturbance at a Brockton hotel on Dec. 1. They said they found the 39-year-old Brown sitting in an SUV in the parking lot, with cocaine in his possession.

The Boston native is the former husband of singer Whitney Houston and stars in the CMT Network show “Gone Country.”
