A friend sez There is a kit being sold, he had the money and said fuckit. Came with synthetic and used a buddy's gf together. Froze the girls pee and just let it thaw to roomtemp. The warmers that came with were bunk, used the walmart ones and monitor the buit in thermometer, he was all good. Unless federal, they will not watch. You are just $$ to these trolls and they are getting paid for counting and shipping urine jars. Warm weather is a plus if there ever was, just beware of the freezing ass lobby! Welcome to the future, While meds or rec is gaining ground the labor dept or whoever won't budge,sure its illeagal but they are violating your rights first right?
But there are those employers who don't mind a little dank in the stank, but its the crank that might raise flags. Its a gamble but with mouth swabs I think 24 hrs is a good start.
