They are getting sneaky with this stuff. Just a routine visit at my GP, which they always previously had me pee in a cup, which USED to be just a dip stick for blood sugar.
Last time, he started yelling at me for nicotine, calling me an idiot for smoking. I had been vaping, but they definitely checked for recreational things, and nicotine, and this was just routine checkup. I think both insurance, and big brother, are pushing this invasive stuff. HIPPA my a$$.
Sorry
@Stlgirl, not trying to worry you, but if, and only if they do Gas Chromatography, there is no hiding anything. The only way around those is abstinence, and obviously you can’t call and ask.
