a generally accepted long term study is 10+ years. in addition you have a larger sample size than 1 person. you also need to have people with different usage patterns. people who were smokers and those who arent. people who are using nicotine and those who arent. you also need proper medical documentation and testing throughout the study. until that is done any attempt to claim that
vaping is safe is unwarranted and is just an opinion. i share your opinion. if i didnt i wouldnt be
vaping. however, anyone who makes the claim that vaping is unsafe is making as true of a statement as someone who is claiming that it is safe. longer term studies are needed. this does not mean that there should be any form of prohibition. it just means that people need to make their own educated decisions.
what is of concern isnt the VG, PG, or even nicotine, but the flavorings. because what is used is just regular food flavorings there can be chemicals which are safe to ingest but not inhale. one thing that would solve every problem is if there were vaping specific base flavorings. those flavorings would be tested for any chemicals which would potentially be harmful since the contents of PG, VG, and Nic vapor are already known. the unknown element has always been the flavoring. making a simple statement such as "People want to know exactly whats in them I suppose because they can't memorize 4 or 5 ingredients" is deceptive because one of those 4 or 5 ingredients contains hundreds of ingredients. you would be surprised what goes into making artificial flavorings. most of that stuff will do some serious damage. however, if processed properly almost all of the harmful elements is extracted. the more money and effort a company is willing to put into removing the harmful elements the better the end product will be. if you dont believe me im sure you can find the steps to making artificial flavoring online. one of the primary components is either. either will kill you. im kind of surprised that no company has stepped up to make flavorings for us. it would solve so many potential issues.
