Potency refers to the strength or effectiveness of a substance, particularly in the context of pharmaceuticals or herbal remedies. It indicates how much of a specific active ingredient is present and how well it can produce a desired effect. For example, a higher potency in a medication means that a smaller dose is needed to achieve the same therapeutic outcome. In the field of cannabis, potency is often measured by the concentration of tetrahydrocannabinol (THC) or cannabidiol (CBD). Products with higher THC levels are typically more psychoactive, while those with higher CBD levels may offer therapeutic benefits without the high. Understanding potency helps consumers make informed choices about their use of these substances.
