Yawn, to often people have grownup in the nanny state where risk assessments are required just for an adult to wipe a child's nose. I walked to school, my own children walked to school. I also used to attend various activities of an evening and walk home alone through unlit parks, my daughter muttered something about it being scary which I resolved by explaining THIS was why it was as safe as a lit footpath as it scared away the "bogey man too "
A little commonsense is all that's required, whether new to vaping or an old hand. It stands to reason that a coil of 0.09 ohms (that melted the big battery ) isn't going to work on an ego battery, yet still people will try it. I managed to singe off my eyebrows playing with fire, I also still have the scars on my leg from fire yet I didn't die and can warn others that petrol vapour might not be visible but it can still hurt you, or that melted plastic behaves like water when you throw rocks in it and splashes of molten plastic are seriously fucking painful on bare skin.
All I'm actually trying to point out is that some people will ask about safety and sub-ohm and some won't give a shit until they're in hospital. Unfortunately, we're following the USA and instantly looking for someone else to blame instead of looking at what's left of our face in the mirror and stating " well,that was a really fucking stupid thing I did "
