Tina says her son, known as 2B, was once a rising rock musician but now is homeless and addicted to heroin. She says that although he has gotten violent with her, she still gives him money and takes care of him when he comes to her house.

2B’s girlfriend, Stephanie, also admits to enabling 2B by giving him money and letting him come to their home, she says, because he begs her for hours for money.

Alexis, 2B’s half-sister, claims 2B has stolen from her numerous times -- and she’s ready for their mom to stop enabling him.

In the video above from after the show, Dr. Phil explains how a chronic disease, like addiction, can affect an entire family – not just the addict.
