Where is weed legal in Europe? The majority of European countries have legalized medical marijuana in recent years, although access remains inconsistent across the continent. A growing number of countries have decriminalized possession of small amounts of cannabis, transforming marijuana laws in Europe so that criminal penalties are largely a thing of the past. However, the marijuana laws in Europe can be confusing, with some countries having legalized only derivatives of the cannabis plant and not flowers or other natural forms of the plant. With the European Union recently legalizing CBD and hemp products, however, it’s important to check the rules before you travel if you are concerned about where weed is legal in Europe.
