Random, representative sampling is encouraged. When dealing with solid cannabis, BOTEC Analysis recommends a "quartering" method that divides the sample into four equal parts and takes portions from opposite sections of a square-shaped arrangement of the sample. For liquid cannabis products, remembering to stir before sample collection is advised.[1] When deriving a sample from a cannabis-laden edible, the QuEChERS approach used by food safety labs for pesticide testing has practical use.[2] In fact, a variety of parallels have been drawn from the food and herbal medicine industries' sampling guidelines, including from the Codex Alimentarius Commission's CAC/GL 50-2004 General Guidelines on Sampling as well as various chapters of the United States Pharmacopeia and The National Formulary.[1][3] As the Association of Public Health Laboratories (APHL) points out, "[g]ood sampling is key to improving analytical data equivalency among organizations," and it provides a solid base for any future testing and standardization efforts.[1]

Additional sampling insight can be found by examining other states' guidelines, e.g., Massachusetts' Protocol for Sampling and Analysis of Finished Medical Marijuana Products and Marijuana-Infused Products for Massachusetts Registered Medical Marijuana Dispensaries[4], as well as ASTM D8334/D8334M-20 Standard Practice for Sampling of Cannabis/Hemp Post-Harvest Batches for Laboratory Analyses.[5]
