But Niki’s sister, Sammantha, says that’s not true. She says she told her parents exactly what Niki was doing, and claims they didn’t believe her. “I begged them to listen to me, and they told me to shut up.”

Niki, who at eight months pregnant admits to shooting up about a gram of heroin every day, says she blames herself for the way she’s living now.
