Bundestag member Jens Lehmann (CDU) is familiar with the opposing viewpoints on handling cannabis. At Grünhorn, he gained comprehensive insight into the subject of therapeutic use.

The relationship between the CDU and cannabis has been somewhat distant, as evidenced by Bundestag member Jens Lehmann, who recently voted against comprehensive legalization. During his visit to Europe’s largest cannabis pharmacy, Grünhorn, he gained extensive insight into the cannabis business beyond the black market and stoner stereotypes: "Today, I learned more about cannabis than in many highly emotional debates," he commented to the Leipzig Volkszeitung. For him, this was proof that the debate on recreational use, which has dominated the political agenda, has greatly overshadowed other potential applications. Sven-Roger von Schilling, CEO of Schurer Pharma & Kosmetik GmbH, emphasized to the politician the importance of removing medical cannabis from the Narcotics Act to promote the decriminalization of patients.

Since 2017, medical cannabis has been legal in Germany and, since 2020, has been distributed nationwide to patients via the Leipzig-based Grünhorn Pharmacy. These patients include those with chronic pain, cancer, MS, sleep disorders, and inflammatory diseases. Lehmann observed the various forms of administration. At Grünhorn, he saw both the packaging of the flowers and the in-house production of cannabis extracts and capsules. Topics such as the meticulous checking of incoming prescriptions and the significance of the Grünhorn Network as an economic site and employer in the region were also discussed. Lehmann, a self-proclaimed local patriot, was impressed by the Grünhorn site in his neighborhood, which he had not known about before.

Lehmann intends to bring this topic to his faction, particularly in his working area of "defense," to explore how soldiers could benefit from medical cannabis, such as in treating PTSD. This idea was partly inspired by the visit of Ukrainian Health Minister Viktor Lyashko to Grünhorn in February, who was preparing the legalization of medical cannabis in his country to provide access to soldiers with post-traumatic stress disorder. Lehmann expressed openness to the possibility of therapy with medical cannabis and emphasized the need to differentiate between recreational use and medical therapies. "I look forward to further exchanges," he said at the end of his visit.
