Robert Downey Jr.'s son being treated for drug abuse Thu-03-Oct-13 17:47 Share this ROBERT DOWNEY JR.'s adult son is undergoing treatment for substance abuse issues. The Iron Man star's ex-wife Deborah Falcone, has revealed 20-year-old Indio is currently receiving "holistic, natural and orthomolecular" therapy at an undisclosed treatment facility. She adds, "We are hoping to do it the homeopathic way rather than with medications. He's being treated with vitamin supplements and organic foods." Falcone explains her son, who is a promising musician and actor, was only taking one prescription pain pill a day and does not have addiction issues. However, Downey Jr. reportedly fears his son is battling the same issues he fought 20 years ago, when he was in-and-out of drug rehab facilities and jail. A source tells the National Enquirer, "This is a nightmare for Robert because his boy has never been in trouble before. He's praying for Indio's recovery."
