"Peer reviewed paper" no doubt written by someone who has never vaped, doesn't know anyone who vapes, and the same is true of his his "peers" who "reviewed" it.
Your health is to important to be put into the hands of "experts"..you have to be proactive and engaged in your own health...otherwise you find yourself at 60 taking 12 different pills a day and have a major surgery every 2 years...a goldmine for the "health care proffesionals"
