I find this very interesting because yesterday, I was talking to an uncle of mine, who was the head of family medicine at Hopkins for 15 years, and is a smoking cessation expert. He is a big believer in nicotine replacement therapy, specifically the lozenges and gum, and believes that nicotine is not the harmful ingredient. I talked to him about ecigs, and showed him my ego setup, which he thought was pretty cool (he said that his patients and the support group that he runs usually carry much bigger "pieces", as mine is a spinner 400 MaH with an evod), but he did start to tow the party line about the FDA needing to look deeper into nic juice and delivery systems just to be sure that there is nothing bad in them.
All in all, I came out of that conversation very pleased that he thought that ecigs were a good idea, and as his nephew, who smoked for over 20 years, he was thrilled that I am no longer a slave to the tobacco.
Can't tell you how pleased I am to read stories such as yours! That your uncle, affiliated with such a prestigious institution, actually has vapers in his cessation group, is really cause for cautious optimism. I hope we'll see more cases like this!
