Lohan, who was busted twice since Memorial Day weekend, was charged with two counts of driving under the influence. If convicted of both, she'd face a minimum of four days in jail. If a felony were filed, Lohan could have faced several years in state prison.
TMZ also explains why Lindsay received just a misdemeanor drug charge:
In Lohan's case, the fact that she was busted twice in a short period of time actually helped her. It shows someone is struggling with an addiction problem. The fact that each time she was busted, she immediately checked into a rehab facility also helped her case. Also, her age - 21 - and the fact that her upbringing was extremely unstable - also worked in her favor.Unstable upbringing? Man, that should be a slap in the face to Lindsay's parents. I mean, even Hitler's parent's weren't called out in the war crimes tribunal. But if having crazy parents is really a valid defense I'm assuming Britney Spears' kid could pretty much massacre a bus full of nuns, children and puppies and still get off scott-free.
