For health insurance I am by for life insurance I'm only a non-tobacco user if I can pass a test for nicotine; or, rather, the lack thereof. The test is extremely accurate and nicotine stays in the system a long time. Doesn't really matter if I consider myself a non smoker. I want their coverage I have to accept their definitions. Another 6 months of vaping 0mg and I'll be able to pass the test and meet their requirements for a non-tobacco user.
Just tell them you really like skin on potatoes pureed with tomatoes. Of course, you wash it down with some green tea.
