In a revealing interview, Noah Centineo opened up about his struggles with substance abuse and his perspective on sobriety. Centineo admitted, "There wasn't really much I wouldn't do. I never, ever injected anything, which is good... I smoked a lot of things. I was really upset, man. It was a really dark time in my life."
The actor also said that he stopped using drugs and alcohol shortly after his 21st birthday. He stayed clean for a year and is now drinking again in a way he considers to be healthy.
Centineo certainly isn't the only celebs who's struggled with substance abuse. Here are four other celebs who have been open about their addictions.
