Understanding the plant

THC, or Tetrahydrocannabinol

THC, or Tetrahydrocannabinol, is a psychoactive compound found in the cannabis plant. It is found in raw plant material, predominantly in its acid form, Tetrahydrocannabinoic acid or THCa. Over time or through heating THCa turns into THC through a process known as decarboxylation.

THC’s chemical structure is similar to a naturally occurring neurotransmitter called anandamide, which interacts with our endocannabinoid system. This resemblance allows THC to bind to CB1 and CB2 cannabinoid receptors in the brain and nervous system.

When THC binds to CB1 receptors, it alters normal neurotransmitter function, and can produce a range of effects, including euphoria, relaxation, and changes in appetite.


Medical cannabis, which contains varying levels of THC, is used to treat a range of conditions. These include:

THC has analgesic properties and can be effective in relieving chronic pain conditions, including neuropathic pain, arthritis, and pain related to cancer or surgery.
