Sadly people for the most part have never learned from History and History does truly repeat itself if you look hard enough.
I totally agree with what you said but unfortunately I think we are about to witness the 22LR scenario with nicotine.
This is truly not the time to panic and max out all your credit cards on nicotine and equipment as nothing is written in stone just yet.
Think about it they are after tax dollars nothing more. The ride might get a little bumpy but it will smooth out as we go along is my belief.
Prepare yourself by weaning yourself off of nicotine while you can, I believe that will be the one thing that ends up getting either hard to get or very expensive for DIY'ers.
Stockpiling more than you can use in your lifetime is certainly not the answer because we all know it does have a shelf life.
A few years after the Y2K scare I was working for a Haz-Mat clean up company and we got called out for hundreds of clean ups of contaminated gasoline leaking from improperly stored 55 gallon barrels. The worst spill that I worked, the guy had stored the gasoline in Haz-Mat barrels with serial numbers that had chain of custody paperwork that allowed the EPA to go knock on his door. I heard that by the time they finished with him he had lost everything he had ever worked for.
I weaned myself off of the stinkies over a period of 60 days after 47 years of 2 to 3 packs a day now almost 1.5 years in I have reduced nicotine from 12 mg to 1.5 mg or less and still headed down so it can be done. You just have to want to do it and I am of the mindset I would rather do it by choice not force.
