Courteney Cox Husband, David Arquette, Enters Rehab: What for?

(CBS) Add David Arquette to the list of actors to have gone into rehab.

"He is in there for drinking and depression, not hard drugs. Rehab was inevitable," People magazine reported.

During a recent interview on Howard Stern's radio show, the 39-year-old actor said his psychologist believed he was having a "nervous breakdown" (the actor later said he was joking) and confessed he'd been "drinking a lot."

"Everybody's worried and concerned about me," he added during the interview. "When I drink, I become a maniac."

Arquette, best known for his roles in the films "Buffy the Vampire Slayer" and "Scream," is reportedly having a hard time dealing with his separation from his wife, Courteney Cox.

"He's just not handling this situation well," a source told the magazine. "He's really depressed."

Nearly 17.6 million adults in the U.S. are alcoholics or have alcohol problems. Heavy drinking increases the risk for certain cancers, and can damage the liver, brain, and other internal organs. It can also cause birth defects.

Drinking also increases the risk of homicide and suicide.

Relapse is common among those attempting to fight alcohol addiction. Let's hope Arquette, who has a six-year-old daughter with Cox, can make rehab stick.
