If you decontaminate the cannabis plant - for example, by using gamma irradiation to reduce the microbial load - you must ensure that this does not adversely affect the quality of the medicinal cannabis product (section 9(a) of TGO 93).
Do not use ethylene oxide to decontaminate the cannabis plant (section 9(b) of TGO 93). This is in line with current guidance on the quality of herbal medicinal products. For more information, see:
Guideline on quality of herbal medicinal products1/traditional herbal medicinal products (EMA/CPMP/QWP/2819/00 Rev. 2)
