Opiates take at least a month to work out of your system. If "they" are doing hair tests, get a hair cut. I will not work for a company that infringes upon my privacy like that. I was once on probation with the state of Tex-ass for one year. Never again. 3 hots and a cot at their expense, if I ever get into trouble again. This has become the Orwellian world that we have all feared. I will not submit to it, other than staying under the "radar".
