Carrie Fisher and Debbie Reynolds
Carrie says she started smoking marijuana when she was 13 years old. Her drug use spiraled out of control in her early 20s, with Carrie taking everything from cocaine and heroin to pain killers and acid.
At age 28, Carrie entered rehab for the first time. "She was doing a film. She had collapsed on the set and they had taken her to Cedars-Sinai," Debbie says. "It was a terrifying night. It was pouring rain, so you can just picture you're in the car with the rain smashing against the windshield and you're crying like mad and you don't know if your daughter's going to be alive when you get there."
