A gay anesthesiologist working at Holy Cross Hospital was arrested last week on charges he purchased crystal meth from undercover investigators and had the amphetamine and the club drug GHB at his home, officials said.

Dr. John R. Habib, 54, of Oakland Park, was charged with trafficking in methamphetamine, possession of methamphetamine and possession of GHB. The charges carry with them mandatory sentences of state prison time, if convicted.

An undercover officer and confidential informant purportedly met the doctor at his house, where they allege they sold him 35 grams of crystal meth- for $1,800. Fort Lauderdale police also reported that a team of investigators searched his home and found more drugs inside.

Habib has been a doctor in Florida since 2000 and has no disciplinary actions against him, state licensing records show. However, he did have a prior drug arrest in 2003. He got his medical degree from the University of Massachusetts in 1987 and did his residency in the Boston area. He has retained Keith Pierro with the Miami law offices of Joel Hirschorn to handle his defense.

Dr. Habib does not work directly for Holy Cross. He works for Florida Atlantic Anesthesia, a Fort Lauderdale medical group hired to supply anesthesiologists for surgeries and other procedures at the hospital, Holy Cross officials said.
