Happy to!
Started it as an alternative to smoking as smoking was stupid money and I'd been dx with a heart condition so also an even more monumentally stupid thing to do.
It let me quit smoking entirely within days, because of course I have swapped the physical habit of holding a fag in one hand with the habit of holding the vape, and I still get the fast nicotine hit from the vape, and the exhale of 'something' which is all part of the physical habit.
I have zero intentions of stopping vaping, however I have reduced the nicotine from the highest content to the lowest which was always the plan. I've been vaping for mmmmm 7 years? I think!
Reasons.. I like the taste (I vape grape and strawberry or sometimes parma violet, reallllllly sweet flavours)... it keeps me off the sweeties which is handy as im diabetic, and irrationally I feel as if I am allowed one 'vice' - I don't drink, not allowed cake (or tbh, food...), I don't go out much as everywhere is so inaccessible...
I am also aware that the chances of me making even retirement age are slim to none and so the 'we may find out in 20 years time that this is HORRIFIC for your health' concerns are not so much of a concern for me. I'd rather enjoy now, because I don't have a 'later' (though I had 10 years about 14 years ago and I am still here soooooo... )
From a health POV - my respiritory health has been significantly better since switching, but then I also don't go out and meet nasty germ filled people much either so thats likely a big factor, but even when I did, I got far fewer colds and lurgies than I did as a smoker!
I do agree, disposable vapes aimed at children are a fucking nightmare and people starting vaping who would never have smoked... thats foolish for adults and scary for kids.
Also the seeming lack of control on illegal, untested vapes does worry me - I buy known brands from reputable companies and know those juices are tested, I wouldn't buy from market stalls or places that had only an online presence though.
I do quite like that there are disposable vapes, that you can buy in the places were we once all bought cigs, but thats more for those vapers who would go back to cigs if their vape battery went flat or they ran out of juice (my sister!).
I am not bothered by not vaping in any of the places I wouldn't have smoked in, im not itching to do it and I don't tend to need to go out for a 'vape break' unless I am really needing a brain-break from whatever it is I am doing.
