^ I went almost 2 years without using for felony probation. I was on suboxone for 18 months of it though, but only was on it to make probation that much easier. I've definitely successfully stopped for drug tests, but the craziest was before I was on suboxone, I would do dope Friday-Sunday, then piss clean each Friday. I would bring bags with me, give my piss sample, and then sniff a few bags in the parking lot of the treatment court place to get well before starting my weekend binge. I would cop every Thursday night, be sick as hell all night, and believe me that Friday test couldn't come any sooner. I've mentioned that it used to take til Thursday for me to get really sick, which is pretty weird since that's 4 days after stopping. I failed one test all my time there, and that was even with giving it 5 days after using, so be careful all you out there trying to beat the system. It was like my second piss of the day, and it was dark so I knew I should have dumped it and given a sample from my next piss since I had drank a lot of water, but figured 5 days after using for 3 would have me pissing clean, and I had to get to work. The lady was nice and dumped it, and told me she wouldn't tell anybody, but to never fuck up again.
