5) Robert Downey Jr.
The “Iron Man” Robert Downey Jr. was heavily addicted to cocaine and heroin. In 1996, he ran naked on the streets of Hollywood chasing ‘invisible rats and was arrested for possession of drugs. Speaking openly regarding the overcoming of his drug addiction, he said “Job one gets out of the cave. A lot of people do get out, but don’t change. So the thing is to get out and recognize the significance of that aggressive denial of your fate, come through the crucible forged into a stronger metal.”
