One of the 'dodgy' components they may have found would have been
Acrolein*.
Very easy to produce in a laboratory-
Some vendors make spurious and ludicrous claims that their product (cartos) are 'equivelent to 20-40 cigarettes'
How they get this figure and are allowed to make these claims is by using a 'puff counter'-a piece of electro mechanical lab equipment to replace the 'traditional' smoking Beagles.
These machines count the amount of puffs from a carto-until they are dry,
well before the 'claimed' 20-40 cigarettes count of equivelent puffs has been reached these cartos will no doubt be too hot to touch and will be emitting high levels of Acrolein, Formaldehyde and other nasties produced by the scorching of the PG/VG and the poly filling.
I have often wondered if the people attracted to sh**-O-Likes (Novices) believe the 'hype' and attempt to make one pre filled carto last 2 whole days (for a PAD former smoker)-there will be countless out there who are dumb enough.
