This is by no means a treatise or dissertation on nicotine solution and all of it's qualities.
There are people who have done intensive, groundbreaking research in the field of eliquid, nicotine solutions and flavoring, and I am merely referencing what I have learned from them.
Dr Konstantinos Farselinos is one of these pioneers, and it is well worth your time to read his work, which is published and neatly packaged for you on his website.
