to the son and you'll hear the comment, i'd much rather give him the money to buy heroin so he don't have to go on the streets and steal and rob for it. sometimes i've heard cases in here where the mother actually drives them to the spot where they pick up their heroin. that's why it's a mama's boy drug for me. >> at 22 years old michael still have boyish looks but said he mother didn't pay for heroin and said she didn't realize he was shooting. >> hit the same spot about a hundred times. even my mom was -- my mom never knew i was doing heroin because i never left track marks. >> he said he started using heroin at age 15. he was well on his way to completing the center's rehab program but recently he signed himself out in order to avoid being kicked out and is back in general population. >> this is my cell. i'm really mad at myself because i only had three weeks left.
