The most frightening thing in Norway is that it has never been allowed to buy nicotine liquid.
They have been talking about it being legal, well, since 2018. Then it should be legalized through EU directives in the summer of 2020, then came the pandemic.
And, that's how far we have come, March 2021.
I think it will be a few more years before there are restrictions on gadgets & juice, maybe never.
When they are going to change the drug law so that you are "allowed" to possess small amounts of drugs for "own" use, I doubt if there will be restrictions on juice etc.
