Adam Jasinski of Delray Beach, Fla., is accused of attempting to sell 2,000 oxycodone pills.
A magistrate judge ordered him held without bail Friday after a federal agent testified Jasinski told him he had been selling thousands of oxycodone pills every month in Florida, Massachusetts, Pennsylvania and New Jersey. In an affidavit, the agent said Jasinski told him he had used the $500,000 he won on "Big Brother 9" in 2008 to buy the pills.
The 31-year-old Jasinski was arrested Oct. 17.
Oxycodone is a prescription painkiller that can produce a heroin-like high if crushed and then swallowed, snorted or injected.
