Pharmaceutical cannabis: consulting and analysis

Our pharmaceutical experts support companies that want to grow pharmaceutical cannabis in Germany or import its flowers and oils.

GMP-certified laboratory location Münster, narcotics licence according to Section 3 of the German Narcotics Act

At our GMP-certified laboratoy location in Münster, 70 experienced employees work with consulting, audits and analyses for the quality and safety of your cannabis medicinal products and hemp products. These services are carried out in our GMP-certified laboratory at our Münster location. This is because the testing with validated methods of medicinal cannabis flowers, oils, or other pharmaceutical dosage forms, in a GMP laboratory, is one of the prerequisites for authorisation in the European market. WESSLING has the required narcotics licence according to Section 3 of the German Narcotics Act from the Federal Opium Agency to be allowed to conduct this type of analysis.
