I'm an employee at Kroger, still haven't done the drug test (it's due on Friday). I haven't smoked since...Monday, May 9th. I may have gotten a whiff of secondhand smoke last weekend though - but it was just a whiff...no smoke came out of my mouth or nose. I went through a drinking binge and repeately washed my mouth with Scope. Haven't touched weed in the last 72 hours, I'm sure. I should pass if I take the Salviva test but I was just wondering...is it possible that Kroger uses different tests such as hair or urine? I doubt it because my co-worker took a mouth swab test so I should be in the clear. But...better safe than sorry, right? So, what does Kroger use for drug testing? Saliva, hair, or urine?
