I think it's time you turned the tables on her ... make her "PROVE" it's unhealthy and just as bad as cigarettes.
If she wants you to prove vaping is better, she needs to back up her end of the discussion.
She will have a lot more research to do than you will. There are no good reasons to smoke real cigarettes.
That's been proven.
You only have to research 4 ingredients PG, VP, Nicotine, and Flavorings.
PG ... PG is a germicide.
Used in ventilation systems of surgery rooms, and office buildings to prevent the spread of germs.
Is the basic ingredients in Sno-Cone, as it makes the flavoring "stick" to the ice.
Used in asthma inhalers, babyfood, pills, all kinds of food in the grocery store, in cosmetics like lipstick etc etc
Ever been to a disco, or concert with a "fog" machine ... vapor, duh, good'ol PG. all FDA approved.
VG ... Made from vegetables, it's in my kitchen and used in cooking,
Is a basis for "trail bars, health bars, etc
Nearly all wines have an appreciable amount of natural VG
Makes a great lotion for softer skin, which the body greedily sucks up.
Again is in most of our store bought food products.
Flavoring ... where do you NOT find it. Does she eat, drink soda, kool aid, juice ???
Nicotine ... Again, does she eat ?? ANYONE who consumes vegetables has nicotine in the system, even the children tested for it.
You can become pretty sick without nicotine in your system, as you body needs and uses it.
There is a long list of illnesses that it is prescribed for ... yes, also for people that don't smoke.
Everyone tests positive for nicotine in the blood and for its metabolites in the urine.
There has never been a large-scale clinical trial of nicotine where anyone tested negative for nicotine.
The last test by the CDC in the USA involved 800 subjects and all tested positive for nicotine at measurable levels, even where the subject was a non-smoker, had never smoked, and had no possible contact whatsoever with smokers.
Many vegetables contain nicotine, and also the co-located and similar compound nicotine acid (also known as vitamin B3 or niacin). Tomatoes, potatoes and several other vegetables all provide dietary nicotine.
Tea often contains nicotine, which after all is one of the reasons it works as a pick-me-up.
Some vegetables such as aubergine (eggplant) contain significant amounts of nicotine.
The key to all of this is to remove the smoke. Without the smoke in cigarettes, consumption of certain specific types of tobacco (and, especially, nicotine consumption alone) can be proven to be ultra low risk.
A large population of people consumed nicotine for decades with no visible health impact.
The issue is not debatable. The Swedish proved it.
Yes, smokers over-do it, but then the body adjusts to the higher levels, and isn't to happy when you try to cut back "cold turkey"
Double whammy .. physical and emotional.
Vaping helps with the "hand to mouth" while we gradually reduce (if we want too) the nicotine level
Since you've quit cigarettes, all the little cilia in your lungs and bronchial passages have become un-paralyzed, so they constantly shove anything your lung tissue doesn't like up your windpipe to the point where you either cough up the offending goop or swallow it.
You've done a healthy thing for yourself, and the people around you.
Make HER prove you didn't.
Like my dad used to say about people with her attitude ... "put up or shut up"
Congratulations on being right, doing right, showing your children a good example, and standing your ground because you know your right.
Since light travels faster than sound, some people appear bright until you hear them speak.
