// Definition
A laboratory document reporting the chemical composition of a cannabis sample, including cannabinoid potency, terpene profile, and compliance testing for contaminants. COAs are both essential for regulatory compliance and controversial for their limitations and susceptibility to manipulation.
// From the Episode
Ryan Lee (Chimera) argued COAs are 'information, neither good nor bad - it's what you do with it.' Johnny Casali described sending samples to different labs and receiving wildly different results, with some labs inflating THC numbers to retain clients. Dr. Mark Scialdone noted that sending 30 samples to 30 labs would yield 30 different results due to method variation. Multiple speakers agreed that bioassay (the nose and smoking experience) remains more reliable than COAs for assessing quality, while acknowledging COAs serve essential compliance functions.
