After the whole chewing tobacco incident I never put a cigarette in my mouth.
I worked with many former miners at a Federal Agency. Many of these folks became addicted to chewing because you cannot smoke underground.
It was not uncommon to be in meetings as one of the few without a spit bottle and tissues. "Hey MisterB, want a chaw?" Yuck.
You ain't lived 'til you've tried to understand someone with a thick regional accent trying to talk with a huge wad of chewing tobacco in his jowl. Or had someone knock over their spit bottle and spray/splash that gunk on your shirt.
Not only was it difficult to launder out, but you reeked of that smell the rest of the day. After just one experience, I always kept an extra dress shirt and tie on the back of my office door. Just in case...
And it's addictive. It was painful watching some of these guys try to quit. Many confided it was worse trying to quit chewing than actually giving up smoking!
