How THC Affects the Brain and Endocannabinoid System
Educational Content · Short Form Video
About this work
This educational video explains the effects of THC on the brain, including its interaction with CB1/CB2 receptors, dopamine release, effects on the amygdala and hippocampus, and impacts on the frontal lobe. It also touches upon the endocannabinoid system and potential long-term effects. The video uses animated graphics and brain diagrams to illustrate the scientific concepts.

What happens in a brain on THC? I'm a neuroscientist. I'm going to explain what happens in a brain on THC. Marijuana's active ingredient, Tetrahydrocannabinol (THC), activates CB1/CB2 receptors in the brain and body. This stimulates the release of dopamine, slows time perception, and dilates blood vessels. The increased dopamine activity induces feelings of euphoria. THC activates the amygdala, which regulates feelings of fear. This makes some people feel anxious or paranoid. It also affects the hippocampus, which is important for memory processing, becoming less active, leading to short-term memory deficits. This decreases activation in the frontal lobe, leading to impaired judgment and reduced focus. THC activates the spinal cord and brainstem, which modulate pain perception and suppress feelings of pain. However, long-term use and dependency desensitizes dopamine circuits, decreasing things like motivation and drive over time. The Endocannabinoid System influences things like mood, memory, sleep, and motivation. Although THC has its own set of benefits and drawbacks, THC's anti-inflammatory, pain-suppressing, and appetite-stimulating effects can be extremely useful for those who need it.
