Wow, looking through your citation, almost all of the reports are because the user had a lung condition prior, or an allergy to glycol. This is merely confirmation bias in a report, at best. This is why they SHOULD be regulated, so the adequate warnings can be expressed and the low quality one thrown out of the market, but it does not show that ALL should just be removed.

We already see that your experience has shaped your worldview, but dont impose that on others.
