Mary Jane Berlin brings a cannabis expo and a music festival together at Messe Berlin from June 3 to 6, 2027. It opens with a B2B trade visitor day on Thursday, then goes public for three days of expo and festival from Friday through Sunday. The organizers call 2027 Season 2, the start of a new chapter after the event's first ten years.
What's inside
The expo floor is where more than 500 exhibitors from around the world set up, covering vaporizers, cultivation, medical applications, cosmetics and lifestyle products. A conference runs alongside it with keynotes and panels on trends, legal developments and business opportunities, plus an exclusive B2B lounge where entrepreneurs, investors and founders can meet away from the aisles.
When the halls close, the party keeps going. The festival runs past the fair's closing time on Friday and Saturday, with food trucks, outdoor areas and a crowd of industry people, artists and fans who stick around for the music. Free water stations are spread across the grounds, so bring a bottle and refill, and an Awareness Team is on site if anything gets to be too much.
Hours by day
Thursday, June 3 is the B2B day, open 11:00 AM to 6:00 PM with no festival. Friday, June 4 and Saturday, June 5 run 11:00 AM to 8:00 PM, with the festival going until 10:00 PM. Sunday, June 6 runs 11:00 AM to 6:00 PM, and the festival wraps at 6:00 PM too. The Mary Jane event app maps exhibitors, stages, food trucks, water stations and ATMs.
Entry rules
Mary Jane Berlin is strictly 18+, and coming with a parent or another adult doesn't change that. Smoking is banned inside the halls and limited to the outdoor area. The event is alcohol-free, possession or use of narcotics under German drug law isn't permitted, and heavily intoxicated visitors won't be let in. Consume responsibly and follow German law.
Security runs bag checks and waits can stack up on busy days, so arrive early. Leave large bags and backpacks, glass bottles, weapons, fireworks, drones, scooters, bikes and pets at home; PET bottles and cartons up to one liter are fine, two per person. A ticket on your phone is all you need at the door.
Tickets
Presale for Season 2 hasn't opened yet, and tickets will be sold through the official Mary Jane Berlin site.
Getting there
Messe Berlin is at Hammarskjöldplatz, and Mary Jane uses the North Entrance. Take the U2 to Theodor-Heuss-Platz or Kaiserdamm, or the S-Bahn (S1, S41, S42, S45, S46) to Messe Nord/ICC. Parking at P1 and P2 in front of the North Entrance is free, but spaces go fast, so public transport is the move. The venue is ground level and barrier-free, and companions of visitors with a B, Bl, GL, aG or H mark get in free.
Berlin gets two big cannabis dates in 2027: ICBC Berlin lands at the Estrel in April, and Cannafest in Prague is the next stop on the European circuit this November. The full lineup sits on the High Rise events calendar.
