The concentration of cannabinoids in a cannabis product, typically expressed as a percentage of THC or CBD.
Potency measures the concentration of cannabinoids in a cannabis product, typically expressed as a percentage of THC or CBD by weight. A flower testing at 25% THC contains 250 milligrams of THC per gram of cannabis. Potency is one of the primary factors consumers use when selecting products.
Modern cannabis flower typically ranges from 15% to 30% THC, though some exceptional batches push higher. Concentrates can reach 60% to 95% THC depending on the type. However, the highest THC number does not always mean the best experience. Research from the University of Colorado found that consumers of high-potency concentrates did not report significantly greater subjective effects compared to those using moderate-potency flower, suggesting diminishing returns at very high concentrations.
Experienced consumers and industry professionals increasingly emphasize that potency is just one piece of the puzzle. Terpene content, the ratio of THC to CBD, and the presence of minor cannabinoids all shape the final experience. A well-grown 18% THC strain with a rich terpene profile can produce a more enjoyable and complex experience than a poorly grown 30% strain. When evaluating potency, consider the full lab report rather than fixating on the headline THC number alone.
