This is a theory that has floated around in my brain for some time now. I figure if you can taste sweetness in the vapor, but not ingest the sugar content then it could be a sweet substitute. Then, there is also the actual eating of sweets that may also contribute the enjoyment of eating sweets that vaping can't substitute. I pretty much figure that ultimately it's about the health risks involved, and only time and research will tell.
I don't know it would work as a substitute. Smelling a fresh baked pie doesn't make you not want pie does it?
No, that's not it. It's not being "closed minded", it's a matter of evaluating risk.
Nobody knows what the long term health effects of vaping are. It's too new. The base fluids, PG and VG, are rated as "safe" for their current uses but inhaling them in vapor form hasn't been tested. "Vaping" is rather a "bet" that the risks are far, far less than inhaling tobacco smoke. A bet I think is probably a good one and one I'm taking. But encourage a non-smoker to take up vaping? Not me. I have no idea what we'll find ten, twenty, thirty years down the road. We didn't used to think smoking was all that bad for you either. It used to be quite "mainstream".
Oops?
Bear in mind that the vast, vast majority (if not all) here are people who took up a habit once and came to regret it. No smoker stopped to think about the risks when he or she lit that first cigarette. Years later, we know the effects. But it's too late to go back.
It's not "closed minded", it's experience.
Is vaping healthy? No idea. Is it healthier? More likely than not. I know I haven't felt this good in years. My blood pressure has fallen back to college levels and I've got more energy than I've seen since the early 2000s. It's making a huge difference. That's anecdotal but, still, it's real. I'm living it.
But if I could go back and do it again, I would chose neither smoking nor vaping. Smoking because I know the risks and know what it's done to me over the years and vaping because I don't know the risks and don't know what it will do to me. So anyone who is at that point I wish I could go back to, my answer is inevitable:
Don't.
Why take the gamble? If it's a way to escape something we know to be a serious health risk, it's worth taking the risk. But otherwise... why do it at all?
