How cannabis becomes medicine
-
The cannabis contains around 5% THC (tetrahydrocannabinol), the psychotropic substance of the plant with therapeutic properties. swissinfo.ch -
The inflorescences are separated from the stems and leaves – painstaking, tedious work that is done by hand. swissinfo.ch -
After the work is finished, only a quarter of the original 150 kg cannabis crop is left. swissinfo.ch -
The approximately 40 kg of crushed cannabis flowers are kept in a refrigerator. swissinfo.ch -
The cannabis flowers are poured into a 70% alcohol solution. swissinfo.ch -
swissinfo.ch -
To remove the THC and other cannabinoids, the solution is stored for at least half an hour at room temperature, and then filtered. swissinfo.ch -
This procedure is repeated two to three times. swissinfo.ch -
The objective is to obtain a solution containing 10 mg of THC per millilitre. swissinfo.ch -
Out of 40 kg of cannabis flowers, around 120 litres of tincture can be produced. swissinfo.ch -
Each production step is standardised and all data are recorded. swissinfo.ch -

The cannabis tincture is then sold in pharmacies. swissinfo.ch -
