It is one of the few things that is good about Norway, we consider vape to be a good health, so far.
2% of the population use vape, most of them are former smokers, and there are so few young people who start, that I doubt if the authorities will make it more difficult in the next 10 years.
The only thing they have regulated is that we go under public smoking law, but in the wording is not considered vape to be harmful to others in contrast to the cigarette, it is simply due to the smell of some juices.
