What Delta-9 THC Is
Delta-9 tetrahydrocannabinol, usually shortened to delta-9 THC or simply THC, is the primary psychoactive compound in the cannabis plant. It is the component most responsible for the high associated with cannabis. When people talk about THC and its effects, they are almost always referring to delta-9.
How It Works in the Body
Delta-9 THC works by interacting with the body's endocannabinoid system, binding particularly to CB1 receptors found throughout the brain and nervous system. This interaction influences mood, perception, memory, and how the brain processes pleasure and pain, which is why it produces the range of effects cannabis is known for.

Common Effects
The effects of delta-9 THC vary from person to person and with dose. Many people experience relaxation, euphoria, altered perception of time, and increased appetite. However, especially at higher doses, it can also cause anxiety, paranoia, confusion, dizziness, dry mouth, a rapid heart rate, and impaired short-term memory and coordination. Most acute effects are temporary and fade as the high subsides.
The Question of Risk and Dependence
While cannabis is sometimes viewed as harmless, regular and heavy use of delta-9 THC can lead to dependence and a cannabis use disorder. Over time, some people develop tolerance, needing more to achieve the same effect, and may experience withdrawal symptoms like irritability, sleep difficulty, and reduced appetite when they stop. Frequent use can also affect motivation, memory, and mental health, and may worsen underlying conditions like anxiety.
