Yea I was surprised to see how many of them were on herion. Especially most of the upper echelon. But like stated above I'm sure depression sets in when you know there is no way out of jail the rest of your life.
Most of them were all doing it on the streets before they got into jail so you can't use that excuse of why they started it but why they continued to do it.
A lot of the prison gangs are run by guys like that, got nothing to lose and want to live as comfortably as possible whilst in jail for the rest of their lives.
