Before doing a club tour, I would start smoking about 2 weeks in advance and yes I put that stuff under my nose. I believe that it did help and, wiping it off, was always dirty. If I didn't smoke before doing clubs, I would violently get sick and want to gag and vomit from all the cigarette smoke so, I had to get used to it by buying a couple packs...
Nothing like a cold night in Nebraska to bring every smoker in the state out to a club so as not to smoke up the house with kids in it...
Sort of like the way gunpowder gets up your nose.
NEWS FLASH there is vicks vaporub in the home!
