I have been mixing my own liquid and use 5% alcohol to thin the VG & PG. I never thought much about it but at my new work I can not drink anytime during the week, I was tested last Thursday and the test showned i had at least a drink within the last two days but I had not. The test must have picked up on the alcohol in the e-cig. I now have to prove that there are e-liquids sold with alcohol in it or prove that it is common to use alcohol when mixing e-liquids. I offered to give them the liquid I had been using but was told that would not work without other evidense. Can anyone help me and tell me where I can find such proof?
