I'm upset by employers who test applicants for nicotine and have a "no hire" policy for "smokers". Apparently vapers test out positive and can't be hired, neither can nic gum users or patch users. Question: How do they test for nicotine; breath or blood serum? How long does it take for nicotine to clear your system if one goes to 0nic vaping? I may be moving soon and would like to have no road blocks getting a job in new state. Anyone know about this?
