It seems to me the major hurdle to get over is getting people to understand the process of vaporizing and the components of most liquids are not a new thing. Resistance heating elements have been around since the dawn of controlled electricity. There are studies on PG dating back to the 40's. Rechargeable
batteries are often misunderstood, but generally accepted by society. Heck, even VG and several of the flavoring concentrates are found in food people deem safe to feed to their children. Somehow by combining several generally accepted components together for a new function people seem to think some malicious intent or unknown danger manifested and is ready to break loose and destroy us all.
I completely understand that nicotine is harmful and addictive, but without the thousands of other chemicals present in analogs it's not anywhere near the point it is portrayed to the general public as. It would be nice if someone were able to get factual and accurate information
through the veil of ignorance and into the hands of the general public.
