The prac`ce of 'lab shopping' has emerged as a significant challenge, undermining the reliability of these results. This phenomenon occurs when cannabis producers, tes`ng laboratories, and retail stores selec`vely report higher tetrahydrocannabinol (THC) concentra`ons and contaminant-free products to boost sales and marketability. Studies have indicated a strong posi`ve correla`on between the THC content in flower products and their sale price.(13) As a result, there is a market-driven incen`ve to report elevated THC levels. 'Lab shopping' not only distorts the true chemical composi`on of cannabis products but also poses significant public health risks. Consumers relying on these skewed results are poten`ally exposed to higher levels of THC than reported, leading to unintended psychoac`ve effects and safety concerns. For all those reasons, cannabis tes`ng imposes significant economic costs on producers and laboratories. For producers, tes`ng increases produc`on costs, impac`ng their already `ght budgets. These costs, in turn, elevate the final sales price of cannabis products, though the exact percentage varies by region and tes`ng complexity. For tes`ng laboratories, high labor costs, par`cularly in sample prepara`on, and intense compe``on create financial challenges, olen leading to thin profit margins.
