Does CBD Have an Intoxicating Effect?
Many people wonder if CBD can make you feel "high" like THC, but the answer is straightforward: CBD does not have an intoxicating effect. While both CBD (cannabidiol) and THC (tetrahydrocannabinol) are derived from the cannabis plant, their effects on the body and mind are quite different.
CBD belongs to the group of cannabinoids and does not produce THC’s characteristic high. Its lack of this intoxicating effect should be distinguished from an absence of effects on alertness, mood or other bodily functions. Further background is available in this published review.
Key takeaways
- CBD does not make you feel high.
- Hemp is a type of cannabis; its origin alone does not establish a finished product’s THC content or effects.
- CBD is non-intoxicating in the sense that it does not produce THC’s characteristic high, but it can affect alertness.
- Distinguishing the CBD molecule from a finished CBD product helps explain why product composition matters.
How does CBD affect the brain?
CBD interacts with the body’s endocannabinoid system (ECS) differently from THC. In laboratory research on CB1 receptors, CBD altered receptor signalling rather than acting like THC. These cell findings help investigate mechanisms; they do not by themselves demonstrate a benefit from a retail product.
The absence of a THC-like high does not mean that CBD has no effects on the brain. Changes in alertness, including drowsiness, and changes in mood have been reported. These effects are relevant when considering the risks of a product, particularly alongside other medicines. See the FDA overview of CBD effects and safety uncertainties.

CBD vs THC: What’s the difference?
Though CBD and THC share a similar molecular structure, they have vastly different effects on the brain and body. THC binds directly to CB1 receptors in the brain, causing the well-known ‘high’ sensation.
CBD should not be assumed to counteract THC or make a THC-containing product safer. Human studies have not found consistent protection, and a controlled trial comparing CBD:THC ratios found no reduction in the measured acute adverse effects at the ratios tested. That finding does not establish the outcome of every preparation or method of use.
Researchers also investigate CBD’s interactions with biological targets beyond CB1 receptors. A proposed mechanism or an observed laboratory effect is not a guarantee of calming effects or preserved mental clarity. Clinical findings, the particular product and its composition remain important when interpreting such research.

Frequently asked questions
Does CBD have an intoxicating effect?
CBD does not produce the characteristic high associated with THC. However, non-intoxicating does not mean that it has no effects on the brain or mental state: drowsiness and mood changes can occur. The effects of a finished product also depend on its other ingredients, including any THC.
How does CBD affect the brain?
CBD has several biological targets and does not act on CB1 receptors in the same way as THC. Laboratory research has described modulation of CB1 signalling, but findings in cells do not by themselves establish a calming or balancing benefit in people. Its effects and risks must be assessed clinically.
What is the difference between CBD and THC?
Both CBD and THC occur in cannabis, but THC can produce a characteristic intoxicating high that CBD does not. Their effects when combined depend on the preparation and circumstances. CBD should not be assumed to cancel THC’s intoxicating or other adverse effects.
Can CBD get you high?
CBD itself does not produce THC’s characteristic high. That is distinct from saying that it cannot affect alertness or cause side effects. A product sold as CBD may also contain THC or other substances, so its effects cannot be inferred from the CBD label alone.
Is there a difference between hemp-derived CBD and cannabis-derived CBD?
Hemp is a type of cannabis. CBD is the same chemical compound whether it comes from hemp or another cannabis variety. Extracts and finished products can contain different amounts of THC and other constituents. Hemp origin alone therefore does not establish a product’s THC content, effects or safety.
