If your cannabis product has a 1:1 THC: CBD ratio, both are present in equal amounts. These are the two most common cannabinoids, or chemical components, present in cannabis. One of the main reasons why so many individuals choose a 1:1 ratio is that the effects are manageable. Cannabidiol has the potential to "tame" or "dampen" the psychoactivity and adverse effects of THC.
If you want to know how potent a product is, always check the tetrahydrocannabinol concentration because it has a psychoactive effect regardless of the ratio. A product containing 3 mg of THC and 3 mg of CBD may not be very psychoactive for certain people, whereas one containing 100 mg of both may be.
