It uses r134a as a propellant, like quite a few aerosols these days.
R134a is a low pressure refrigerant used in chillers, high temp freezers (-5°c ish) car air conditioning systems and older domestic fridges and freezers (its been superceded by butane and propane...).
Under tge kyoto treaty I am not permitted to allow r134 to vent to atmosphere as its damaging to the ozone layer, if it gets ignited it is one of tge many refrigerants that burn off as mustard gas (minimum copper welding temperatures for my application).
Now, I'm no doctor, but would you really wish to inhale a gas that is judged "not safe for the ozone layer"?
That is before we get to the other noxious sounding ingredients that we know we don't need to be in eliquid.
Oh, but its mhra approved? Like fucking chantix was approved? Like if we go back far enough, thalidomide was approved?
No, sorry, it doesn't even fucking look like the cigs I used to smoke, I preferred the artisan custom approach (alright, fucking amber leaf if it makes you happy
).
Fail. In my opinion.
Complete and total fail.
