Of the two Lindsay Lohan is the worst.

Charlie Sheen is what some refer to as a "functional" user. He'll blow $30K on a night of debauchery, but that's on his own time. You never hear any stories about him coming to work impaired. And his dad has shown a genuine concern for his behavior, recognizing the disease that Charlie has.

Lohan, meanwhile, has a history of coming to work in an impaired state. That's why she hasn't had a real gig in years. Now she's resorting to stealing to support her lifestyle, stuff that goes on everyday in the big city and would otherwise fall into the category of "dog bites man" save for her celebrity status. And her mom is the classic enabler. Lindsay's rehab stays aren't the result of parental intervention, they're court ordered because of her criminal actions.
