Cameron Douglas was arrested July 28 by the DEA at a hip Manhattan hotel.  The 30-year-old son of Michael and his ex-wife Diandra, has a lengthy history of drug abuse, rehab, arrests and imprisonment.

The bust took place at the Gansevoort Hotel, a source told The New York Post.  An undercover DEA operation allegedly found he was carrying about eight ounces of crystal meth, and had dealt $18,000 worth of the drug at the time they took him into custody.

Michael’s rep was unavailable for comment.
