There is no better way to determine cannabis flower quality than by reading the laboratory test results. Lab test results spell out the cannabinoid and terpene profile, as well as a screen for contaminants. A  good idea whether cannabis was treated well from seed to the dispensary shelf, only lab testing results can give you demonstrable insights into what is actually inside your flower. If you are uncertain about the cannabis flower you’re considering, always ask to see the lab test results – these can be illuminating in making a final decision. .
