Started vaping in 2009, have not looked back since. This is a healthier alternative to cigarettes (we all know that), not very interested in saving, although it is a plus, more interested in stopping cigarettes.
I smoked cigarettes for over 30 years, after the first vape, I stopped and have not had one since.
Vape Pros
I can smell
It is a healthier alternative
My lungs are clear and my heath is great
I can breath
My clothes, vehicle, home, etc no longer smell
I save money
I can stay in the good hotel rooms
No more outside in the cold and rain puffing away on a cigarette
I can avoid "smoking areas" because now I cannot stand the smell of a cigarette.
Regarding the FDA, there are always ways, maybe vaping will never go main stream, but for committed vapers, we will continue. Keep in mind there are other forms of Nicotine besides that which comes from tobacco. No one can ban wicking materials, wire will always be around, stainless metal parts will always be available, Batteries cannot be banned, electrical parts will still be there.
Vaping hardware and liquid is so generic, good luck making them go away.
