There are some instances of more strict rules in Europe. Since Norway does not belong to the European Union, it has its own laws regarding vaping. The use of e-cigarettes is permitted, but the sale of products that contain nicotine is not.
Believe it or not, there are a number of countries where vaping is illegal. Brazil, Singapore, the Seychelles, and Uruguay.
In Singapore, the laws are very strict. E-cigarettes and e-liquid are prohibited and the use of them is illegal. Those guilty of the offence are liable to a fine of up to $5,000 upon conviction, even tourists.
