When Jessey first met Niki, he says he didn’t use drugs at all. In the video above, Jessey says “I was hoping if I started doing heroin that Niki would feel bad and she would stop using.” But Jessey says that didn’t work, and now he’s addicted too.

Jessey says it was his choice to start using, but Niki says she feels responsible, “like I pretty much took away everything he had.”
