Confused about cannabinoids? We break down the key differences between CBD and THC, their effects, and medical applications.

Cannabidiol (CBD) and Tetrahydrocannabinol (THC) are the two most prominent cannabinoids found in the cannabis plant. While they share the same chemical formula, their atoms are arranged differently, leading to distinct effects on the body.

Psychoactive Effects

The main difference is that THC is psychoactive, meaning it produces the "high" associated with marijuana use. CBD, on the other hand, is non-psychoactive and does not cause intoxication.

Medical Benefits

Both compounds have medical benefits:

  • THC: Effective for pain relief, muscle spasticity, glaucoma, insomnia, and low appetite.
  • CBD: Used for anxiety, depression, inflammation, seizures, and migraines.

Legal Status

In the US, CBD derived from hemp (containing less than 0.3% THC) is federally legal. THC remains federally illegal but is legal for medical or recreational use in many states.

The Entourage Effect

Many experts believe that CBD and THC work best together, a phenomenon known as the "entourage effect." Using full-spectrum products can enhance the therapeutic benefits of both cannabinoids.
