The importance of Foreign Matter Analysis
Like all medicinal herbal materials, Cannabis should be entirely free from contamination by anything that’s not part of the plant. This includes moulds, insects, other animal contamination or excreta, other plants, soil, stones, etc. Some countries allow values as low as 2 ppm (0.0002%) for faecal matter or as high as 5% for mould or other foreign matter, but you decide what is acceptable for your herb. We’ll check it for you.
