What is the primary psychoactive compound in marijuana?

The primary psychoactive compound in marijuana is THC, or tetrahydrocannabinol. This compound is responsible for the effects commonly associated with marijuana use, such as euphoria, altered perception, and relaxation. When marijuana is consumed, THC binds to cannabinoid receptors in the brain, which plays a significant role in its psychoactive properties and its impact on various bodily functions.

Understanding the role of THC is essential because it helps to differentiate marijuana from other substances that may be misidentified as having similar effects. For instance, while cocaine, methamphetamine, and heroin are also substances that affect the brain, they have entirely different chemical structures and mechanisms of action, leading to different effects and risks associated with their use. This knowledge is crucial for anyone studying substance abuse trends, pharmacology, or public health implications regarding marijuana and other drugs.
