Brolin explained in a 2014 interview that during his teenage years, he was a member of a surfing friendship group who called themselves the "Cito Rats". In his description of the group, he stated: "It was Santa Barbara. It was the \'80s. It was punk rock. 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." He admitted to stealing cars to pay for his drug use, which included heroin, a drug that he explained he did not like: "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."\n', '
