Jailhouse Junkies (S07E05)

Two jails: one in California, the other in New Jersey. Both have amongst the toughest drug policies in the United States. But still drugs find their way in... In Cali, crystal meth is the jail drug du jour, while in Jersey a deadlier drug rules: heroin. Two different drugs, two different kingpins, two different jails: officers versus inmates in a battle for ultimate control. (National Geographic)
