The Eye film museum in Amsterdam will next month hold a conference focused on encouraging investment in cannabis products, the Parool reported at the weekend.

Processing the marijuana plant in drinks and chocolate, for example, is a major trend with offers great investment opportunities, the organisers say.

Michael Kraland, who is behind the conference, says that American and Canadian companies are currently leading in marijuana-based products, but that laws make this more difficult in Europe.

Recent major deals include the €3.8bn which drinks company Constellation Brands put into Canopy Growth,  which grows medical cannabis. And Heineken owns an American company named Lagunitas, which in turn produces Hi-Fi Hops, a non-alcoholic cannabis drink.

Two analysts from Germany bank Berenberg Bank will analyse the Constellation deal at the convention, and there will be various firms who are active in the industry, including Dutch medicinal marijuana firm Bedrocan.
