Dennis Quaid
Quaid wrote an essay about his 1980s cocaine addiction in “Newsweek” after having “one of those white-light experiences that night, where I kind of realized I was going to be dead in five years if I didn’t change my ways.” The actor checked himself into rehab in 1990 for a 30-day stint and afterwards didn’t touch drugs or alcohol for a decade.
Drew Barrymore
Barrymore had her first drink at age nine, began smoking pot at 10, and took cocaine at 12. Her first time to rehab was for substance abuse when at age 13, and she went twice as a teen. After her struggles she wrote an autobiography in 1990 titled “Little Girl Lost.” Barrymore wrote, “I was this seven-year-old who was expected to be going on a mature 29.”
