The grandson of billionaire businessman Marvin Davis, who was part of the last series of U.S. reality show Celebrity Rehab, was picked up by cops in Newport Beach on 27 January (11) for alleged drug possession and placed on $20,000 (£13,330) bail.
Now he has been formally charged for the offence, and was also charged with misdemeanours of being under the influence of a controlled substance and possessing drug paraphernalia, reports TMZ.com.
According to legal documents from the Orange County District Attorney's Office, Davis was allegedly high on a "central nervous system stimulant (prescription medication) and narcotic analgesic (painkillers)" at the time he was arrested.
He faces up to three years behind bars if he is convicted of all the charges.
Following his arrest Davis released a statement accusing his family members of calling cops and releasing details to the press in a bid to boost their own public image.
The day before his run-in with police Davis also appeared on a live reunion episode of Celebrity Rehab, in which he insisted he had been clean since completing treatment last year (10).
