I found this article extremely interesting and actually saw factual information used that we all talk about all the time in regards to throat hit, pg/vg ratios, allergies. Even to the extent that some users recommended Marshmallow flavoring to help moisten dry juices, which I have read many times myself. I’m glad that some people are finally willing to do some research using actual experiences of users vs rumors. It’s a very good read 
A very long way to go, but positive signs of a willingness to learn.
