I don't know why the parent said "Europe", unless they did a survey of all the laws. Drugs are mostly regulated at the country level.
You are right, my use of "Europe" was too broad.
Afaik, 5 years ago it was only available in the 1mg amount (which in the light of this article, would be good). I once ordered some online that was 3mg, and the customs almost fined me for illegal drug importing.
