I've never been a vapor!! But I'm a smoker!!!.... Wake and baker...and cig smoker for over 30yrs.. So I think its safe to say... Been There ..Done It!! This is only a theory and I am only speculating here.. But if you constantly draw into your lungs high heated amounts of butane/?? (however the heating element gets its spark)... can not be good for your lungs.. Seems to me it would cook them!! Even though we have used Butane lighters forever.. think about it... you only light a cigarette once.. These vape smokers light it at least 5 times in a half an hour... I guess what I am saying is that it is not the Flavor or the THC... I feel it's in the heating element etc.. Just One Thought!!
