Is the exhibition barrier-free and what applies to accompanying persons in case of severe disability?
Messe Berlin is a ground-level and therefore barrier-free event space. If the symbol “B”, “Bl”, “GL”, “aG” or “H” is in your disability pass, admission is free for the accompanying person. All you have to do is buy a ticket for yourself.
What does the trade fair offer that I can't find online?
While information is available online, the Mary Jane trade show offers a unique opportunity to experience products directly, meet experts in person, and participate in live workshops and discussions. In addition, the local networking experience is irreplaceable — here you can make direct connections with like-minded people and experts.
Why should I visit the fair if I'm not a cannabis consumer?
The exhibition is not just for consumers, but for anyone interested in the diverse uses of cannabis, including its role in wellness and medicine. In addition to discovering new products, there are also educational events that offer deeper insights into the health, legal and cultural facets of cannabis.
Do I have to print out my ticket to enter or is it enough on my mobile phone?
