Cathine is a natural stimulant found in the leaves of the khat plant, which is native to East Africa and the Arabian Peninsula. It is chemically similar to amphetamines and is known for its mood-enhancing and energizing effects. People often chew the leaves of the khat plant to experience these effects, which can include increased alertness and euphoria. In many cultures, particularly in Yemen and parts of Somalia, chewing khat is a traditional social activity. However, the use of cathine and khat has raised health concerns, as excessive consumption can lead to negative side effects, including insomnia, anxiety, and dependence.
