This one was a doozy. At the start of season 3, Jack was dealing with a heroin addiction that began during his time undercover with the Salazars. Throughout the first half of the season, Jack tried to detox while dealing with the days events and almost used a couple times. However, in episode nine when hes back undercover, Hector Salazar gives Jack some pills to deal with his symptoms, and apparently that solved everything. Jack didnt experience any more negative side effects and his addiction never bothered him again for the rest of the series. Does someone know where you can buy these magic pills?
