I know this is from way back, but one thing I found out about is 'PG Free vap'. They use vegetable oil rather then proplene glycol because some people can not tolarate PG.
If you went back to smoking, you might want to consider PG free stuff.
What?!.. and change my habits in exchange for a couple of decades? Seems a bit risky.
I would certainly try any reasonable alternative to smoking that didn't involve some perception of personal sacrifice.
I can't remember now exactly but I think what I was using had a mix of the 2. One gives you the bite and the other gives you the visual smoke.
Unfortunately, my governments have all decided that it should be difficult for me to access the otherwise available options. No doubt that I could find it if I decided to but I haven't followed the product development since my initial experience.
It's a shame really. I buy gray market cigarettes because the taxes are unreasonable when I would gladly pay twice as much for a healthier option that actually satisfied.
It's a strange thing. I fully appreciate the irrationality of the habit and yet I remain captivated.
