Would love to offer up better comparisons... but there's nothing comparable. What do you suggest?
OTOH, there are tons of testimonies from people who have vaped for a number of years, claiming better lung function is common to pretty much all of them. If it is bad for your lungs, I don't see how we'd have so many of these testimonies.
When i am confronted with combative folks on the matter i try to be upfront and honest and not play the game of i am right and you are wrong.
Nobody on either side of the fence has the science to back up what the long term effects will be for vaping pro or con, but we do have the science on the harms of tobacco. Thus far, vaping is light years away from the many thousands of known harmful chemicals in cigs compared to eliquid that is only made up of 3 main ingredients PG VG NIC...with a optional 4th ingredient flavorings. While flavorings are in question at this time, the 3 main ingredients are pretty well studied for ingestion and in some cases inhalation such as a asthma inhaler, but inhaling PG/VG in high quantities on a daily bases day after day is an exposure rate that has not been studied for long term effects. There are many things that are safe when used in moderation only and whether that is true for PG/VG or flavoring is yet to be determined, but when compared with tobacco and it's many deadly complexities of ingredients...vaping is far more transparent in what your inhaling and very limited IMO on things that are unknown that could possibly cause problems.
When i encounter combative people while waiting in a waiting room and my vaping pen shows in my purse or falls out...sparking a discussion...this is my position of discussion on the matter and i can tell you i have had more success with this approach then i would have had with pulling all this ANTZ, PROPAGANDA spewing hate and insisting they are wrong because look PG/VG is in cough syrup or vicks vapor rub... blah blah blah. Come on folks we can do better then this.
Side note: Katemama, vapers who are feeling better because they quit smoking is no surprise, but that is not to say that years down the road vapers won't start feeling the negative effects of vaping...after all....nobody felt bad for years when they started smoking..heck many felt better!! until years of smoking and the feel goods of smoking started rearing it's ugly head. I have no doubt vaping is going to have a few ugly heads itself it will rear in time, we are already seeing it with setbacks regarding health concerns with flavors.
