While generally holding more progressive stances on healthcare, labor rights, and prison reform than the United States, Cannabis legalization is one category that lags behind. The European Union, while maintaining economic ties, is not a uniform block though, and national governments are free to implement their own laws. This makes the changing landscape of cannabis legalization complicated, especially when you add the variable of hemp derived Delta-8 THC.
Western Europe vs. Eastern Europe
Currently, Malta is the only country in Europe that has fully legalized recreational consumption of cannabis, but Germany is expected to do so in the short future. , Many other Western European countries have also adopted a decriminalization stance, including Portugal, Spain, and the Netherlands. In Eastern Europe, medical cannabis is permitted in Poland, Romania and Greece, with the Czech Republic permitting not only medical cannabis but also decriminalized possession for recreational use.
Delta-8 Legality Status
Owing to the fact that Delta-8 is hemp-derived, its European classification is as a “novel food” and not as a narcotic.  Because of this, Delta-8 products are legal throughout the European Union, subject to pre-approval by the European Commission. This means that Delta-8 products are legal and regulated within the European Union, and are available for purchase in a variety of stores depending on which country you are in.
While Delta-8 products are legal now in Europe, its status is far from certain. In November 2020, The European Court of Justice confirmed CBD as a Novel Food, shooting down a challenge that Delta-8 products should be re-classified as narcotics. As well, the ubiquity of cannabis, be them Delta-8 or Delta-9, are far less common in Eastern Europe as they are in Western Europe. Currently, there are 14 countries in Europe that have decided cannabis possession of any kind will not lead to incarceration, compared to 17 countries where incarceration is still possible. Cannabis legalization remains a shifting target, and it may remain that way until Europe develops a more concrete plan.
