THC (tetrahydrocannabinol) is the primary psychoactive compound found in cannabis. It is responsible for most of the psychological effects- such as the ‘high’ – that some people experience when they consume cannabis.
THC is not illegal and can be prescribed for patients with a mental or physical health condition which has not responded to first line treatments. Combining THC with CBD (cannabidiol) is often considered effective for managing the symptoms of various conditions, as CBD can help counteract some of THC’s effects.
