Mechanism of Action

Delta-9 THC exerts its effects by activating CB1 receptors, primarily located in the brain and central nervous system. This activation triggers a series of events that modulate neurotransmitter release and alter brain function. One of the main outcomes of CB1 receptor activation is the inhibition of neurotransmitter release, particularly gamma-aminobutyric acid (GABA) and glutamate.

The inhibition of GABA release by delta-9 THC changes neural activity, affecting mood, memory, and cognition. Additionally, the suppression of glutamate release contributes to the relaxation and sedative effects commonly associated with cannabis use.
