The hard-luck son of Michael Douglas pleaded guilty on Wednesday to dealing large quantities of methamphetamine and cocaine while holed up in a trendy Manhattan hotel where he was arrested last year. Cameron Douglas, 31, told a judge that a New York contact first asked him if he could score the drugs in 2006. After that, “I began supplying on a regular basis.” Asked by a judge if he knew what he was doing was wrong, he replied, “Yes, your honor.” Prosecutors said Douglas had signed a plea agreement, but the details weren't disclosed. In addition to conspiracy to distribute drugs, Douglas pleaded guilty to heroin possession - a charge stemming from allegations that his girlfriend tried to smuggle him the drug in an electric toothbrush while he was under house arrest. He faces a minimum 10-year prison term at sentencing on April 27. Investigators say Douglas was paid tens of thousands of dollars for trafficking methamphetamine - what he referred to in intercepted phone calls as “pastry” or “bath salts.”
