Analysis of Medicinal Cannabis

Since March 2017, general practitioners and specialists in Germany have been allowed to prescribe medical cannabis in various forms, such as flowers or extracts, for serious illnesses. Due to THC contents above 0.2 %, these products are subject to the German Narcotics Law (BtMG). The handling of these products therefore requires a BtM permit from the Federal Institute for Drugs and Medical Devices (BfArM). QSI is in possession of this permit and is therefore able to carry out analyses of cannabis/preparations.

In addition to the many analyses of the DAB and Ph.Eur. this includes in particular the determination of cannabinoid content as well as the testing for impurities (pesticide residues, mycotoxins, heavy metals, microbiology, etc.).

QSI holds a manufacturing permit according to § 13 AMG. The Qualified Person of QSI monitors the processes and can take over the batch release within the scope of the manufacturing permit.
