Sept. 21, 2010— -- In the tweet heard 'round the world, Lindsay Lohan confirmed late Friday that she'd failed a court-ordered drug test – an outcome that could send her back to jail, under the terms of her probation. TMZ.com reported that the actress had also tested positive for cocaine last week.

Now Lohan's probation has been revoked, and a bench warrant has been issued for her arrest. The warrant is on hold until 8:30 a.m. Friday morning, when the 24-year-old actress has been ordered to appear in court.

"A judge will routinely revoke probation when he receives a report from a probation officer, under oath, that the probationer has violated a condition of probation, such as illegal drug use," said Dana Cole, a criminal defense attorney and partner in the law firm Cole and Loeterman, in Los Angeles.

Supportive friends and fans may have cheered Lohan's openness and applauded her tweet that said, in part, "…i am trying hard." Foxnews.com reported that the actress had even joined Alcoholics Anonymous.

But the questions remain. With her personal life in such disarray, why would Lohan want to share the turmoil with even more people? Why use Twitter to communicate her shortcomings?

"The time she has already spent in rehab may have had a positive effect on her expressing her feelings, including remorse for having failed the drug test. The tweet may not have been manipulative at all," said Cole.

Shari Corbett, a psychologist specializing in addiction behavior and the senior executive director of Promises Treatment Centers in West Los Angeles and Malibu, told ABCNews.com that "people with substance-abuse problems don't want to relapse. No one wakes up in the morning and says, 'I think I'll humiliate myself internationally today!' Relapses are extraordinarily common. And relapsing is not a logical decision made in the frontal lobe. It's made in the reptilian part of the brain that's associated with craving." It's that craving that may well help explain the significance of the tweet, she added.
