Friends say Lindsay Lohan may not be able to comply with a court order to stay away from drugs and alcohol. As in, Linds may not be physically capable.

When the train wreck shows up in court tomorrow, Judge Marsha Revel will almost certainly lay the smack down, telling her to cut out drugs and alcohol.

Period. Legally.

Judge Marsha Revel talked Thursday about the conditions of her bail - refraining from consuming alcohol, wearing a SCRAM bracelet to monitor alcohol consumption, and submitting to random drug testing at least once a week.

A friend says that's a joke: "She can't make it through a day ... She's a mess."

Another source says Lohan "wakes up with cravings and satisfies them fast." Somehow we're not surprised. But will she be required to go clean Monday?

NO CANNES DO: Lindsay Lohan going clean? Forget about it.

Probation violations aside - she's already in deep for missing her mandatory alcohol education classes - the judge could revoke bail for drinking or drugs.

If that Lindsay Lohan cocaine pic is any indication, we give it a day.

Don't ask us what the point of alcohol education classes even is when she goes out partying until the wee hours of the morning almost nightly, but hey.

Stay tuned there. In other Lindsay news, the person who wired Lohan's bail money at lightning speed last Thursday also helped Britney Spears in 2008.

Lou Taylor is considered a behind-the-scenes wheeler and dealer who pushes some pretty controversial born-again views ... and is now on Team Lindsay.

Taylor is not only considered genius in the money department, she's a huge personality with a moral force that easily rivals her Husband, who's a minister.

She is not shy at all about pushing her born again religious views, something that scared the hell out of Britney Spears. Can she do the same for Lindsay?
