CBD and THC are the two most well-known compounds in cannabis, but they produce very different effects. Understanding these differences helps you choose the right products for your needs.
What Are CBD and THC?
Both CBD (cannabidiol) and THC (tetrahydrocannabinol) are cannabinoids - chemical compounds found in cannabis plants. They interact with your body's endocannabinoid system but in different ways.
The Key Difference: Psychoactive Effects
THC produces the "high" associated with cannabis. It binds directly to CB1 receptors in the brain, altering perception, mood, and consciousness.
CBD does not produce a high. It interacts with the endocannabinoid system indirectly and may actually reduce some of THC's psychoactive effects.
