CBD and THC are the two best-known cannabinoids in cannabis. Although they have similar structures, they affect the body differently. Here’s a quick look at the difference and why some shoppers prefer THC-free CBD oil.

Differences and similarities between CBD and THC

Cannabidiol (CBD) and tetrahydrocannabinol (THC) are compounds found in cannabis plants that act on different receptors in the brain.

Hemp and marijuana come from the same cannabis plant, but they’re classified differently. Hemp contains up to 0.3% THC, while marijuana can contain anywhere from 5% to 20% THC.

What Does THC Stand For?

THC stands for delta-9-tetrahydrocannabinol, one of the main psychoactive compounds in cannabis. It binds to CB1 receptors in the brain and can affect perception, memory, and mood. CBD and THC are both cannabinoids, but they work differently. In CBD products, THC is usually limited to trace amounts depending on local rules.

In brief summary:

THC is psychoactive, meaning it affects mood, perception, and other mental processes. THC is responsible for the intoxicating effect of marijuana.
CBD is generally non-intoxicating.

What is cannabis oil?
