Dr. Drew recently appeared on “The Joy Behar Show” to talk about Lindsay Lohan's condition.

“The reality is, she has an illness,” Dr. Drew said. “Advanced addiction has a worse prognosis than the vast majority of cancers. It has a treatment. The treatment works.”

Dr. Drew later explained, “the stuff she’s doing is very, very typical, particularly of my female patients very early in recovery … they do lots of strange things. I’m very fearful about Lindsay. I think we’re going to see a very serious bottom in the not so distant future."
