I personally think ecigs are an interesting experiment in free markets. A bunch of like minded people who had a habbit which was the leading cause of preventable death coming together to figure out a way to kill themselves less. Have there been things in the industry which were poisonous and could kill you over the course of it's history. Yes. Lots. Have those been slowly fased out as concerned consumers voice opinio…
So your argument is that because e-cig users are coming from one harmful product, that we should do nothing to prevent the new product from causing undue harm, and that eventually (decades?) e-cigs will become safer because someone (who?) will eventually phase out the harmful ones? Why not stop wasting time and lives, and prevent the harmful ones from being produced/released?
Ni200 which is a pure nickel wire was invented for temperature control. Required a specific device and chip to use as it has almost 0 resistance. Some stupid uneducated people or vendors sold it and and used it in non temperature controlled devices and poisoined themselves (not fatally), or blew up their batteries on non-regulated devices.
I just started vaping last month, and while I bought some kanthal wire, I also bought some ni200 and Titanium wire, which is dangerous if not used correctly. I personally didn't know, but also didn't use it until I looked it up.
With that said, ni200 wire did invent temperature control, which is a method of vaping these days.
