You sure it wasn't 2 years and a minimum of 6 months? thats what they gave me and i was off it in 9 months. Goodbehavior and clean piss is how you get off. Eventually the meetings will be about 5 minutes long and you and your p.o. will have nothing to talk about. Then they figure " We can't throw this guy in jail, might as well let him off." Thats how its supposed to happen. But more often than not people keep smoking and dig giant holes for themselves with their drug testings and end up fucked. So either quit smoking or never fail a drug test.
