A lot of unnecessary angst and hand wringing over something we have absolutely no control over. "Adapt or die." Smoking is a
choice some have opted to define their lives around. Tobacco use is a luxury not a necessity. If it has become such ... my sympathies. We opted into our wee vice at a time when society was turning, correctly I believe in the mid-50's , against tobacco use. If you are so tied to smoking that you see your world collapsing you've invested too much of your life into a triviality. "Adapt or die!"
Sooner or later, some here are going to have to "suck it up" and find another diversion/obsession to spend time and moneys on. I'll cover my thoughts by observing, I'm too old and too sick to worry about the situation myself. My sympathies to those whole world seems to revolve around tobacco.
