Delta-9 THC (tetrahydrocannabinol) is the main psychoactive compound found in cannabis. It is primarily responsible for the euphoric “high” that people experience when consuming marijuana. When Delta–9 THC enters the body, it binds to cannabinoid receptors in the brain and central nervous system, affecting mood, memory, perception, and motor coordination. This interaction leads to the characteristic effects such as relaxation, heightened senses, and altered perception of time.

In addition to its recreational effects, Delta-9 THC has potential therapeutic uses, including pain relief, anti-inflammatory properties, and appetite stimulation. However, its legal status varies depending on the region, with some areas permitting its use for medicinal or recreational purposes, while others continue to prohibit it.
