In a short time, Germany has become the most important cannabis market in Europe. When Mary Jane Berlin opened in June 2025, the organisers expected around 60,000 visitors and more than 500 exhibitors from all over the world. The fair reflects the change taking place across Europe, where both medical cannabis and adult use are becoming increasingly normal.
Update: The fair set a new record with more than 65,000 visitors, compared with around 41,000 the year before.

From subculture to global movement
Mary Jane Berlin was first held in 2016 and has since grown from a niche event into one of the largest cannabis fairs in the world. In 2025, the fair took place from 19 to 22 June at Messe Berlin and the adjoining Sommergarten. Visitors could see everything from new growing technology and product launches to debates on politics and international cooperation.
Artists such as Samy Deluxe and Haiyti performed in the festival area. Food from around the world and smoke-free zones made the fair a meeting place for curious visitors and professionals alike.
Medical and recreational cannabis are both driving growth
Since 1 April 2024, adults in Germany have been allowed to carry up to 25 grams of cannabis in public and keep 50 grams at home, as well as grow three plants for personal use. Since summer 2024, they can also join non-profit cannabis clubs. At the same time, medical cannabis is no longer classified as a narcotic in Germany but as an ordinary prescription medicine. We look at how the reform has worked out in our article on Germany’s cannabis law two years on.
The reform has created a fast-growing market. Imports of medical cannabis rose sharply in 2024, and as the stigma fades, new groups of adult consumers have joined the market.
Europe is changing and Germany’s role is decisive
The fact that Germany, the most populous country in the EU, has chosen to partly legalise cannabis affects the whole continent. Countries such as the Netherlands, Switzerland and Malta were early movers, but now a broader movement is emerging where more countries choose to regulate rather than prohibit.
Mary Jane Berlin is an important meeting place in this development. The trade day brought together around 5,000 participants, and at the conference some ninety speakers discussed everything from exports and sustainable production to healthcare and consumer protection.
Where technology, culture and community meet
The fair showed everything from small greenhouses for the balcony to growing technology, accessories and new products. The range attracted both curious beginners and experienced enthusiasts.
The organisers focused on a safe and pleasant environment with smoke-free halls, quiet zones, international street food and so-called awareness teams. The festival area was completely alcohol-free, a deliberate choice to put cannabis culture at the centre.
Mary Jane as a symbol of a new era
After the record year, founder and organiser Nhung Nguyen was delighted. She described the development as incredible and called Mary Jane the most important event in the international cannabis calendar.
