An insider tells Star that Lindsay will be under the care of Matthew Torrington, M.D., medical director of the PROMETA Center, an outpatient clinic in Santa Monica specializing in treating alcohol, cocaine and metamphetamine (crystal meth) addictions.

The PROMETA system is at the center of a major controversy within the medical community though. "In my clinical experience, I have found the treatment to be very, very effective and an incredible aid to people who are suffering," Dr. Torrington tells Star, but the lack of accepted clinical testing, say some critics, raises many troubling questions about the PROMETA program.

"At this time, there is no peer-reviewed research that has been done on the treatment," David Kan, M.D., a substance-abuse expert at the VA Medical Center in San Francisco, tells Star. "There is also no evidence to suggest it is productive."
