THC and CBD are two of the most well-known compounds found in the cannabis plant. While they both come from the same plant, they have very different effects on the body.

THC, or tetrahydrocannabinol, is the psychoactive compound in cannabis that produces the "high" feeling when consumed. It binds to receptors in the brain and nervous system, leading to a sense of euphoria and relaxation. THC is often used recreationally for its intoxicating effects.

On the other hand, CBD, or cannabidiol, does not produce any psychoactive effects. Instead, it has been shown to have numerous potential health benefits. CBD interacts with the body's endocannabinoid system to help regulate functions like mood, sleep, pain perception, and immune response. It is commonly used for its anti-inflammatory and analgesic properties.

In terms of legality, THC is typically illegal in many places due to its psychoactive properties. CBD, on the other hand, has been legalized in many countries because it does not produce a high and is considered safe for consumption.

In summary, while both THC and CBD come from the same plant and have therapeutic potential, they have very different effects on the body. THC produces a high feeling and is often used recreationally, while CBD offers non-intoxicating benefits without any psychoactive effects.
