I live in Norway, where e-cigarettes can be sold but not the liquid (if it contains nicotine). I know that e-liquids can be imported from other EEA countries, but the postal tax can be pretty steep. I'm going to the US soon and was hoping to bring as much back with me as possible (my mom lives there, so I can just ship it to her), but can't find anything that says whether or not this is ok. So, has anyone taken e-liquids over international borders (especially from the US to somewhere in Europe)?
