Chemical Structure of THC and Its Effects on the Brain

Understanding the chemical structure of THC (Tetrahydrocannabinol) is crucial for comprehending its effects on the human brain and body.

THC vs CBD: Understanding the Differences

THC and CBD (Cannabidiol) are both cannabinoids found in cannabis, but they have different properties and effects. THC is known for its psychoactive effects, which alter a person’s state of mind and can lead to feelings of euphoria. In contrast, CBD is non-psychoactive and is recognized for its therapeutic properties, often used for medical purposes without causing a ‘high.’ Both compounds interact with the body’s endocannabinoid system but in different ways, making them valuable for various reasons.

The Science Behind THC’s Effects

Molecular Structure and Brain Receptors

THC’s molecular structure is similar to the brain chemical anandamide, which allows it to be recognized by the body and alter normal brain communication​​. This structural similarity enables THC to bind effectively with cannabinoid receptors in the brain, particularly CB1 receptors. When THC attaches to these receptors, it disrupts the normal functioning of various brain regions and communication between these areas.

Impact on Brain Functions

1. Altered Neurotransmitter Release: The binding of THC to cannabinoid receptors alters the release of neurotransmitters in the brain. This alteration affects a wide range of mental and physical functions, including pleasure, memory, thinking, concentration, movement, coordination, sensory, and time perception​​.
2. Effects on Specific Brain Regions:
   • Amygdala: THC can induce feelings of fear and anxiety when it attaches to receptors in the amygdala​​.
   • Hippocampus: It disrupts signaling in the hippocampus, impairing short-term memory​​.
   • Cerebellum: THC affects the cerebellum, leading to impaired coordination and altered sense of time​​.
   • Cerebrum: It can impair thinking, attention, decision-making, and alter sensations in the cerebrum. In predisposed individuals, it can cause symptoms of psychosis, including hallucinations and delusions​​.
   • Basal Ganglia: THC raises dopamine levels in the basal ganglia, which may reinforce the behavior and potentially lead to addiction​​.

Long-Term Effects and Cognitive Impairments

Persistent use of THC, particularly when exposure begins in adolescence, may lead to long-term or possibly permanent adverse changes in the brain. Studies have shown cognitive impairments in adult rats exposed to THC during adolescence, with structural and functional changes observed in the hippocampus. Human imaging studies have yielded mixed results; some suggest alterations in brain connectivity and volume, particularly in areas related to executive functions, in regular marijuana users. Moreover, substantial evidence indicates that marijuana use can cause functional impairment in cognitive abilities, with the degree of impairment varying based on the age of initiation and duration of use​​.
