I totally agree that reality TV often exploits people - unfortunately too many people are more than willing to be exploited.
Do we have anything to gain from this? Will disturbingly graphic scenes of intravenous drug use and it's consequences make us better people?
I do think that this could help people realize the horrific results of drug use and possibly help keep people and kids away from the junk. Not saying it's right or good, but there could be some benefit from it.
