Cannabis testing facilities play a crucial role in ensuring the safety and potency of cannabis products, both for recreational and medicinal use. These facilities primarily focus on human safety by testing for harmful substances such as residual pesticides, heavy metals, microorganisms, and mycotoxins that could be absorbed by cannabis plants during cultivation. The products are also tested for potency, with a certificate of analysis provided to confirm cannabinoid concentrations, such as THC, and terpene profiles, which directly impact the effects experienced by users. Regulations and permissible limits are set by international organizations to maintain safety and consistency. When setting up a cannabis testing lab, it's essential to adhere to state-specific regulations and determine whether the lab will test for recreational, medical, or both types of marijuana. Medical testing typically places more emphasis on evaluating the therapeutic potential of terpenes, while recreational testing ensures product consistency and safety.
