Can I Fly with Weed in Europe?
No. Flying with recreational cannabis is illegal across Europe, even between countries or cities where it is tolerated. Airport security operates under federal/national laws, and cannabis is a controlled substance in international air travel.
Detailed Answer
Flying with recreational cannabis anywhere in Europe is illegal and strongly discouraged, regardless of the legal status in your departure or destination city. International air travel is governed by national and international law, and cannabis remains a controlled substance under the 1961 UN Single Convention on Narcotic Drugs, to which all European countries are signatories.
Even flying within a country where cannabis is legal or tolerated carries risks. For example, while cannabis possession is legal in Germany, airports are federal spaces where security may confiscate cannabis or refer you to police. In the Netherlands, cannabis is technically illegal despite the tolerance policy, meaning airport authorities are not bound by coffeeshop rules. Being caught with cannabis at an airport can result in confiscation, fines, criminal charges, or denial of boarding depending on the country.
Crossing international borders with cannabis — whether by air, train, car, or boat — is a separate and more serious offense in most countries. EU Schengen zone open borders make it physically easy to cross between countries, but customs and border police do conduct random checks, and drug-sniffing dogs are deployed at major transit points. Being caught transporting cannabis across borders can result in drug trafficking charges, which carry severe penalties in many European countries.
The only exception involves medical cannabis patients traveling with properly documented prescriptions. Even then, the rules are complex. Within the Schengen area, patients may carry up to a 30-day supply with proper documentation (a Schengen certificate signed by a health authority). For non-Schengen travel or travel to countries that do not recognize foreign medical cannabis prescriptions, carrying cannabis remains illegal regardless of medical status.
