Lohan Joins Celeb Rehab Revolving Door

July 25, 2007 — -- It was in her pocket, but the cocaine wasn't hers.

That's the latest statement from Lindsay Lohan, who is back in rehab for the third time after being arrested for allegedly driving under the influence and cocaine possession early Tuesday morning.

"I am innocent … did not do drugs they're not mine. I was almost hit by my assistant Tarin's mom. I appreciate everyone giving me my privacy," Lohan wrote in an e-mail to "Access Hollywood" host Billy Bush, the show reported on its Web site Tuesday night.

Just in time for the Friday release of her latest film, "I Know Who Killed Me," Lohan, 21, joins the ranks of celebrities like Robert Downey Jr., who has been in rehab four times, and Daniel Baldwin, who has checked into rehab nine times.

These celebrities and many others have spent hundreds of thousands of dollars for treatment at posh rehab centers that from the outside look more like spas. To outsiders, rehab for Lohan, arrested less than two days after checking out of Promises Treatment Center in Malibu, Calif., seemed to be more of a vacation than a cure.

"Didn't she just leave that rehab center in Malibu? Promises? I hope she kept the receipt," Jay Leno joked on his show Tuesday night. "What is the Promise? They keep the room ready for you?"

Is it possible that luxury inhibits recovery and that the pampering is counterproductive? Those who run such facilities say no.

"It's not like it's this incredible spa, like they get massages in the morning and at night. … That's a joke. It is a treatment center," said Howard C. Samuels, the executive director of the Wonderland Center in Malibu. "They're up at 7:30 in the morning. They have to make their bed and if they don't know how to make their bed, we teach them."

Wonderland, one of the facilities Lohan attended, costs $40,000 a month and offers special services for clients in the entertainment industry, such as a sober escort to a film set.

Samuels, a recovering addict, argues that the extras help get reluctant patients in the door. The perks ensure that "the addict or alcoholic doesn't have an excuse not to come into treatment," he said.

The Betty Ford Center, started by the former first lady, has a stricter reputation as a rehab facility, but it has famously attracted its fair share of celebrities over the years, from Liz Taylor to Keith Urban.

There, celebrities pointedly get the same treatment as anyone else, including daily chores like cleaning the bathroom.

"They're distraught and frightened and very sick," Betty Ford said in a 2002 interview with ABC News' Elizabeth Vargas. "And then, weeks later, I see them and they have a smile on their face."
