The Grand Duchy of Luxembourg is one of the smallest (998.6 sq miles, pop. 626,108) and richest ($112,045 per capita) countries in Europe. (It is actually the third richest in the world.)
Its location on the border of Belgium, France and Germany has given it an outsized importance in the European Union, so its moves to legalize cannabis will have a significant impact on other EU countries. It was also a part of the Benelux free trade group that ultimately became the European Union.
From August of 2019, see Luxembourg to be first European country to legalise cannabis.
Unfortunately, the pandemic has delayed legalization, but it also seems to have increased demand for medical cannabis.
