Tetrahydrocannabinol (THC) is the cannabinoid most commonly associated with the psychoactive or intoxicating properties of the cannabis plant. Pharmacologically it is described as a partial agonist at the CB1 receptor, which underlies its central nervous system effects.
In the Australian regulatory framework, THC is treated as a controlled drug. Medicinal products containing THC above defined thresholds are generally listed under Schedule 8 and require prescribing under strict conditions, often through pathways such as the Special Access Scheme or an Authorised Prescriber.
From an educational standpoint, THC is significant both as a defining chemical marker of cannabis potency and as a reference point for the legal distinctions drawn between cannabinoids.
