As with beer, according to the ideas of the industry representatives, there should also be a "purity law" for cannabis in the event of legalization. The cannabis industry industry association presented proposals on Thursday. One paper recommends special quality requirements, such as standards for quality assurance in production facilities, specifications for packaging and storage, or limit values ​​for impurities, heavy metals, or pesticides.

The proposals were created in cooperation with experts from cultivation, laboratory and food control, said the Vice President of the association, Dirk Heitepriem: "Only with the highest and controlled quality can we successfully push back the illegal market and thus achieve the goals of the federal government for health and safety achieve youth protection." The proposals should help to establish a "purity law" for cannabis as a stimulant, it said.

The SPD, Greens and FDP had agreed in their coalition agreement to introduce "the controlled sale of drugs to adults for recreational purposes in licensed shops". Federal Minister of Health Karl Lauterbach (SPD) presented the first concrete ideas for implementation, so-called key points, in autumn. The next step is to present a draft law by the end of March. Due to possible legal concerns in the EU, it is still unclear what will become of the project.
