OK, then YOU do the research, and the the user manage their OWN risk.. JUST DON'T REQUIRE IT.. I prefer NOT to have to pay for this research, via the cost of
vaping. The Cost of research and regulation is WHY I
vape instead of smoke. I don't need research to tell me that stupid people do stupid things that can hurt them.
I also KNOW that approx 75% of the cost of a car, is from making it safe.... Yet I'm still damaging the environment, even with emissions reduced by OVER 90%. And people still get hurt crashing into things. I know all the taxes and regulations on cigarettes didn't do anything to make smoking safe. Just more expensive.
Don't make me look for some other way to get a little enjoyment from life.
