My son-in-law successfully quit smoking by stepping down through vaping.
Do they actually want more people to keep smoking cigarettes?
I wife and I switched 8 years ago after forty years of two packs of Marlboros a day. Never looked back, and feel healthy as a horse.
I have a lifetime supply of concentrated liquid nicotine in the freezer and blend my own e-liquids at 10% of the cost of pre-made from vendors.
I suppose you can call me an FDA prepper.
