Introduction
The levels at which toxins and impurities must be controlled in medicinal cannabis plant products are defined in Therapeutic Goods Order No. 93 (Standard for Medicinal Cannabis) (TGO93). The survey described in this report was conducted to test for the presence of selected toxins as specified in subsection 12(1) of TGO93 for medicinal cannabis plant products.
Testing
Products that met the description of dried cannabis, floss or buds were targeted in this survey. Details of the samples received for testing are outlined in Appendix A. At the time of requesting, samples for two of the requested products were not provided. This is due to one product been discontinued and no stock being available for the other. Sample details and the reasons for not providing a sample are given in Appendix B.
A total of six medicinal cannabis floss products were tested by an accredited third-party testing laboratory. Testing on each of the received medicinal cannabis products assessed the quality, and conformance with selected tests in subsection 12(1) of TGO 93. Samples were tested for the presence and quantity of aflatoxins, ochratoxin A, heavy metals and pesticides.
The limits for the specified toxins are outlined in Table 1.
