What is Khat primarily known for?

Khat is primarily known for being a stimulant plant that can be chewed. The leaves of the khat plant (Catha edulis) contain active compounds called cathinone and cathine, which have stimulant effects similar to amphetamines. When chewed, these leaves release these substances, leading to increased alertness, elevated mood, and a sense of euphoria. This practice is culturally significant in certain regions, particularly in East Africa and the Arabian Peninsula, where it has been used for centuries in social and ceremonial contexts.

In contrast, the other options describe different types of plants or substances. Sedative plants brewed (often referring to teas) do not apply to khat, as its effects are not sedative but rather stimulating. Hallucinogenic plants typically refer to substances that induce altered states of consciousness, which is not characteristic of khat. Lastly, narcotics derived from the opium poppy refer specifically to opioids like morphine and codeine, which are fundamentally different in origin and effects compared to the stimulant properties of khat.
