It depends on age really. Those of us stocking up for "life" are a bit older, and it's easier to stock up for 25 years... but 50? Thats a different story.
My son refused to stock up at all because he saw himself as too young to do so.. and yes, did also decide just to return to smoking.
In the end it's personal choice...
I'm one of the older folks who has essentially stocked up for life. And, I certainly understand the situation for younger people who have switched to
vaping!
On the other hand, if, for whatever reason, I had to give up vaping, there is no doubt in my mind that I'd have an easier time giving up vaping than I would have had ditching cigarettes without the benefit of vaping. Not saying it would be effortless, but easier. And, also without a doubt, I would do just that. There's no way in hell I will ever return to smoking regardless.
Personal choice with a pinch of reasoning and the awareness that smoking is a deadly habit.
