People use the leaves and buds of the khat plant and the leafy green shrub that can grow to tree size.
The chewing of khat leaves is common in some countries of east Africa and the Arabian Peninsula. It has a deep-rooted social and cultural tradition in some Muslim, Somali and Yemeni cultures. In some Muslim countries in which alcohol is prohibited, khat is commonly used in social situations, although it is often condemned on religious grounds.
There is no safe level of drug use. Use of any drug always carries risk.
The effects of taking Khat with other drugs including over-the-counter or prescribed medications can be unpredictable and dangerous.
