THC and CBD: understanding the difference

Cannabis contains dozens of active compounds called cannabinoids. The two most studied are THC and CBD. Understanding their difference helps explain why a practitioner chooses a specific product and ratio.

THC

THC (tetrahydrocannabinol) is responsible for cannabis's psychoactive effect — the feeling of being 'high'. In a medical context it's often associated with managing pain, nausea and appetite. Because it's intoxicating, it calls for careful dosing, especially at first.

CBD

CBD (cannabidiol) is non-intoxicating: it doesn't produce a high. It's studied notably for anxiety, inflammation and sleep. Many patients prefer a CBD-rich ratio when they want to limit psychoactive effects.

The THC:CBD ratio

Most treatment plans combine the two in a ratio chosen by the practitioner based on your goals and tolerance. There's no universal dose: you generally start low and adjust gradually, with follow-up.
