Wifey and I - both lifelong smokers - did that until a few years ago, when we discovered "Vaping" (E-cigs).
A few months ago, she had a medical procedure which required her to lie still for most of the day, so it was a hoot to 'vape' right in her curtained cubicle for the entire period - and nobody came close to popping wise.
FReepmail me if you want details on Vapor 4 Life....the switch was a snap for both of us, with no looking back.
Thanks, but no. I grow my own tobacco.
