Smoking is NOT dead. The Tobacco Industry lobbies hard to criminalize many aspects of the Vaping movement. There is a section of the ECF dedicated solely to the litigation and legislation we are confronted with in nearly thirty states.
And Vaping does not have a guaranteed future. I can honestly admit that I feel better, breathe better, sleep better and have more energy vaping than I did the last several years of smoking, but that would be 'anecdotal'. Vaping hasn't been around long enough for there to be many real scientific studies. Often the data given is bought and paid for by people who want a specific answer, such as tobacco lobbyists trying to squelch competition, or career politicians looking for revenues.
Vaping is a choice. There are no requirements, no mandates, no doctrines.
I started this thread just to see if there were others who choose to vape single coils. Apparently there are still a few of us who enjoy what some might disdain as "Tootle Puffers". Lower voltages, more flavor and less vapor. Most who have posted here would agree with this style of vaping. Many, including myself, have tried sub-ohming with two coils. I personally found two 0.7 coils producing over 40 Watts wasn't something I cared for. To each their own. I also believe it's a safe bet that most who frequent this thread are really not impressed, at all, with the size of your 'clouds'.
There are plenty of other threads for that.
