How Cannabis Brands Use COAs to Improve Transparency Trust is important when consumers are choosing cannabis products. With different cultivators, brands, strains, and product formats available, shoppers often want more information than what appears on a package. A Certificate of Analysis (COA) can help provide that information by showing laboratory testing results for a specific cannabis batch. A COA can include cannabinoid and terpene results as well as testing information for certain contaminants. By making these results accessible, cannabis brands can give consumers a clearer picture of what they are purchasing. This is particularly valuable because cannabis products can vary from one batch to another. Transparent brands can use COAs to support accurate labeling and demonstrate that their products have undergone required testing. Consumers can also compare the reported information with the laboratory results instead of relying entirely on advertising claims. In California's regulated market, consumers should purchase cannabis from licensed retailers. Brands such as Weedroads, STIIIZY, Cookies, and Glass House Farms are recognizable names consumers may encounter, but product quality and terpene or cannabinoid profiles can differ between individual batches. Before purchasing, consumers should check the package information, batch number, testing details, and available COA. A COA doesn't automatically mean a product is right for everyone, but it provides useful information for making a more informed choice. Ultimately, accessible and understandable testing information can help cannabis brands build credibility, accountability, and long-term consumer trust.
