Cassidy^[1]'s a wanted man ... for all the wrong reasons.

There's a warrant out for the Philly MC's arrest in New Jersey for failing to appear in court last week for a hearing in his drug possession case ... this according to the Jersey City Municipal Court.

TMZ broke the story ... the rapper was arrested and booked^[2] in November for possession of marijuana and drug paraphernalia.

There's a presumption of innocence on the drug charges, but he's definitely guilty of not setting a reminder to get his butt to court.
