The major trick to get the electric ones to work properly is to only suck very slowly and gently.
If you suck too hard and fast, the liquid on the heating part dries up and runs out. It needs to be able to continue to feed onto it, so slow and gentle.
And you need to hold them with the tip pointing down, not up.
The refillable vapourising systems are vastly, vastly superior to the lookalikes.
The "arguements" for the crackdown are:-
That they will be attractive to youngsters because of the sweetie flavours, so they will start smoking cigarettes, having tried electric ones.
That the use of electronic vapourisers will somehow "normalise" smoking cigarettes again, undoing all the work of campaigns to make it unacceptable.
Then there are the downright fibs.
They explode (
one early Chinese one did)
There is harm from the "second-hand vapour breathed out". (There isn't. Proven in scientific tests.)
The juices are full of poisons. (Absolutely not, when they're properly made by reputable companies.)
I've even read a comment, from somebody claiming to be a nurse, saying that; "the juices condense into a pellet of heavy metals".
I replied she'd better tell the alchemists!
