Understanding THC and CBD: A Deep Dive into Their Differences and Relationship

Understanding THC and CBD: A Deep Dive into Their Differences and Relationship


Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are two of the most well-known compounds found in cannabis plants12. While they share a similar chemical structure, they interact with different receptors in the brain and body, leading to distinct effects12.

Chemical Structure

Despite having different pharmacological effects, both CBD and THC share a similar chemical structure. They both contain 21 carbon atoms, 30 hydrogen atoms, and 2 oxygen atoms2. However, a slight difference in how the atoms are arranged accounts for the difference between CBD and THC2.

Psychoactive Properties

THC is psychoactive, meaning that it affects your mood, perception, and other mental processes1. It produces the “high” effects of marijuana1. On the other hand, CBD is not psychoactive in the same manner as THC3. It does not produce the high associated with THC3. Instead, CBD can make you feel relaxed1.

Medical Benefits

Both CBD and THC have potential therapeutic benefits. They can increase relaxation and sleepiness, improve mood, and relieve pain1. However, there are some variations in the uses of each substance. CBD is typically used to help treat inflammatory bowel disease, seizures, depression, inflammation, psychosis or mental disorders, and migraine2. THC has potential uses in treating glaucoma, muscle spasticity, low appetite, and insomnia2. Both substances may be used to help treat pain, anxiety, and nausea2.

Side Effects

There are very few side effects with either CBD or THC2. According to the World Health Organization (WHO), CBD is generally safe and does not appear to have abuse potential or the ability to cause harm2.


While CBD and THC are both cannabinoids that come from the cannabis plant, they have significant differences. Understanding these differences is crucial for anyone interested in using these substances for their potential therapeutic benefits. Always consult with a healthcare provider before starting any new treatment or supplement.
