Originally, the German government planned to allow the sale of cannabis for adults in specialist shops but for now, this has been ruled out.Instead, such sales are to be trialled in a second stage of the legalization process, in model regions, backed by scientists, following government talks with the European Commission.In Germany, the possession of a maximum of 25 grams of cannabis, and the cultivation of a maximum of three plants at home are to be exempt from punishment in future. Under the revised legalization plans, the next step will be a draft law on the regulation of possession, cultivation and what are known as cannabis social clubs, later this month.
