Michael Lohan tells his daughter Lindsay won't beat her drug problem if she continues treatment at Betty Ford.

The Rancho Mirage, Calif., facility has treated numerous celebs - including the late Anna Nicole Smith - and Lindsay, 24, became its latest patient on Tuesday (it is her fifth stint in rehab).

"Look at the 'short' list of people who went to Betty Ford -- most, if not all, have relapsed," he tells Us. "I went there myself, and I will tell you, Betty Ford is a country club. They administer prescription meds and even put their patients on prescription meds. Once more, they don't have family therapy at all."

Michael tells Us family therapy is key to his daughter's recovery.

"The root of her problems is her family," he says. "This will not work -- mark my words!"

Still, he tells Us he is relieved "to know Lindsay is in a safe place and away from her enablers."

But "if Betty Ford gives her any prescription drugs, they become another enabler," he tells Us. "Back to square one!"

Lindsay is due back in court Oct. 22.
