Josh Brolin revealed that he has taken the class-A drug in the past and most of his friends who he grew up with are now dead.
Josh Brolin has had a documented struggle with alcohol in the past, and was admitted into rehab late last year (2013).
But the 46 year-old recently revealed he also has suffered from substance abuse, and was even a heroin user.
In a candid interview with The Guardian, Brolin stated, "I tried heroin, that sounds so horrible when you put it like that. But yeah, I tried heroin."
"I mean, I never got into it and I never died from it, which is a good thing. I've had 19 friends who died. Most of those guys I grew up with, they're all dead now," he continued.
The 'Gangster Squad' actor was also a member of the 'Cito Rats,' a gang of surfers with a bad reputation, in the early 80s. But Brolin insists that it was more of a group of like-minded friends, from different backgrounds.
"It was Santa Barbara. It was the '80s. It was punk rock," he said. "You either had the children of rich, neglectful parents or children of poor, neglectful parents, so it was a mix. But we basically grew up the same way. I've never seen a group like that before or since."
2013 wasn't a great year for the 'Men In Black 3' actor, his 8-year marriage to Diane Lane ended, with the pair filing for divorce in February 2013, which became finalized the following November.
Also in November, Brolin entered a rehab facility in Northern California, following a string of alcohol related incidents that occurred in the prior months.
The 'Oldboy' actor described to the newspaper how last year was a "tuning point."
"It made me think of a lot of things. My mom dying when I was in my 20s. All the impact that had on me that I hadn't moved past; I was always such a momma's boy," he explained. "But I realized that I was on a destructive path. I knew that I had to change and mature. It was like I stepped back and saw the hamster wheel."
