An arrest warrant has been issued for Lindsay Lohan as a result of her two failed drug tests ... the first failure due to cocaine.

X17online has learned that Lilo's probation has been revoked and that Judge Elden Fox has issued a bench warrant until 8:30 Friday morning. That's when the actress is due in court.

According to the terms of Lindsay's probation, the actress might have to return to jail for 30 days.

Over the weekend, Lindsay tweeted, "This was certainly a setback for me but I am taking responsibility for my actions and I'm prepared to face the consequences."
