There are numerous testing methods, tools, and procedures for testing cannabis. Any sample submitted for testing will first get subjected to microscopic and visual inspection to look for molds and any contaminants. A testing lab will also look for residual solvents, microbial contamination, potency, terpenes, and physical contamination. Post this analysis, the perfect tool or method for treating any issues, if any should arise, is prescribed.
After the visual or microscopic analysis, the clean sample is subjected to specific solutions to separate cannabinoids from plant material. The obtained cannabinoid solution is further tested with high-pressure liquid chromatography. Thin-layer chromatography (TLC) and gas chromatography (GC) can also be used for potency testing.
Prices are lower for a low THC level and vice versa. As a result, lab testing and inferences are very crucial. The Farm Bill of 2018 has helped the standardization of testing labs in more legal terms. Assured test results and accreditation to the ISO/IEC 17025 standard is preferable.
