Kelsey Grammar says that drug addiction almost killed him. He was addicted to alcohol and cocaine. His habits spiraled out of control after his younger sister was raped and brutally murdered. He has said that he had a love affair with cocaine. It was his drug of choice.
He has also dabbled with ecstasy and valium. He went to rehab in 1990. He also checked himself into the Betty Ford Center in 1996 after a series of drunk driving and cocaine possession arrests, which ended with Grammar accidentally flipping his car while he was intoxicated.
