“The composition of the particles is dissimilar & likely to have a different health impact. Aerosol part. from EN&NNDS consist mostly of a mix of aqueous/humectant droplets, whereas part. in tob smoke are mostly complex organic constituents that contain (..) carcinogens.” (2/ 6)

“There is moderate evidence that young never-smokers who experiment with EN&NNDS are at least twice more likely to experiment with smoking later. The data available so far do not, however, prove that this evident association is causal.” (3 /6)

“Flavours seem to play a part in promoting the switch from combustible tobacco products to EN&NNDS.” (4 /6)

“Users tend to seek rewards from flavours across the whole range of available nicotine products. In other words, when the desired flavour is not available from the desired nicotine product, a proportion of users may seek it from a second-choice nicotine product.” (5/ 6)

“non-pregnant adult smokers who completely switch from combustible tobacco cigarettes to use of unadulterated and appropriately regulated EN&NNDS alone might reduce their health risks. This potential has been recognized by WHO, NASEM and the CDC.” (6/ 6)
