I failed a PEth test (378ng/100ml) when I had not consumed alcohol for 12 days. And before then, I had only consumed 18 standard drinks (spread out) in the preceding 5 weeks. I have a theory that the ethanol in my e-cigarettes may be responsible for the high reading. Does anyone have any information about this? Or, any info at all on how the reading could have been so high, when my alcohol consumption should have been well within the acceptable limits? I am going to lose time with my sons, and thousands of dollars because of this. I would appreciate any help, or information anyone could provide. Thank you.
