CSI star Gary Dourdan pleaded guilty to two felony possession charges of cocaine and ecstasy at his arraignment in Indio, California, on Wednesday.

The first charged against him — felony possession of heroin — was dismissed.

TMZ.com first reported the news.

The actor, 41, was ordered to complete a treatment program, at which time the charges will be dismissed, according to TMZ.

Police arrested Dourdan April 28 after they found him asleep in his car, which was parked on the wrong side of the road, in Palm Springs, Calif., in the early morning hours. After searching his vehicle, they confiscated the drugs.

In an e-mail with Access Hollywood, he initially denied the drugs belonged to him.

"I am blessed that the Sgt. realized that the luggage carrying whatever they found was not mine and that my tests have been coming back negative," Dourdan said. "I've been happy to cooperate in any way to clear myself and go on with my blessed life."
