In 20 years are they going to say the complete opposite like how eating over 2 or 3 eggs per week was going to kill us? Now eggs are considered not so bad for us as once reported! Same with many, many studies! What should we believe and when? Whatever we do seems to be toxic or not at 20 year repeated studies! The whole world is toxic in certain levels at some time!!! Tells us that most things are based on some group mostly worried about money other than actual honest truth! Happy vaping to those smart enough to keep researching with a "grain of salt"! One way or the other we are going to die eventually! So pick your poison! Our polluted air is going to be our demise if not something else! Who takes much stock in these ever changing statistics anymore? You live and you die eventually from something. Concerning our eternal life in the next life is the most important part of this existence in my book! Seems like that is of the utmost importance by comparison!!!
