S-40.1, r. 1 - Regulation under the Act respecting the Québec correctional system

Full text
36. Administrative segregation lasts 72 hours. It ends before that time if the inmate expels the contraband. It may also be extended once for a 24-hour period if the manager in charge has reasonable grounds to believe that the inmate has taken medicine to prevent expelling the contraband. In addition, a new administrative segregation measure may be imposed if an inmate has again ingested the contraband.
