He was using heroin at the time he made his earlier videos. In one of these he mentions taking suboxone and he says he's been cutting the dose down and he notices he giggles easily. But his nose isn't running and he's not sweaty and shaking so he doesn't seem in withdrawal. I just think he seems way stressed. I imagine he doesn't have many people close to him who can smack the tinfoil off his head and bring him down to earth. Kind of sad, really. Everybody hates Herro, but you know, we need that challenging shit. It's good for us, like vegetables.
