I vape around 3 -4 ml of 24mg per day depending on if I'm busy or not. I vape in my office at work...it's not that it's not allowed...there simply isnt a vaping rule at work because they havent had to make one yet...my boss doesnt care...especially if I make sure he doesnt see it..he insinuated that to me not long ago....fortunately, unlike smoking, I can vape at work and no one can really tell since it dissipates quickly and doesnt leave much, if any odor...
