Celebrity | Cameron Douglas Cameron Douglas Fails Drug Test, Sent to Solitary Latest in long line of prison struggles for Michael Douglas' son By Evann Gastaldo Posted Jan 21, 2013 9:49 AM CST Copied In this April 27, 2009 file photo, Cameron Douglas, son of Michael Douglas, arrives at a film premiere in Los Angeles. (AP Photo/Chris Pizzello, File) The troubles continue for Michael Douglas' son Cameron: He's currently serving a 10-year prison sentence for drug dealing, yet even while on the inside he was busted for doing drugs. He failed a urinalysis earlier this month and was sent to solitary confinement, a source tells the New York Post. It was the second setback this month, after Douglas was earlier injured—possibly as a result of "prison justice" after being labeled a rat. Last year, Douglas' original sentence was doubled after he admitted to having drugs smuggled in. No word on whether his sentence will be increased once again.
