What is khat?

Khat is a stimulant drug, which means it speeds up the messages going between the brain and the body. Chewing khat is part of some social traditions in parts of the Middle East, such as Saudi Arabia and Yemen, and in Eastern Africa, such as Somalia.1, 2

The buds and leaves of the khat plant (Catha edulis) are chewed for stimulant and euphoric effects, and traditionally have been used for medicinal purposes as well as recreationally.1 Khat contains cathinone and cathine, which are the chemicals that produce the stimulant effects.2

Other names

Qat, kat, chat, qaad.

What does it look like?

The leaves and buds of the khat plant, either fresh or dried. They have a mild aroma and an astringent, faintly sweet taste.1, 3

How is it used?

Khat leaves and buds can be chewed fresh, but may also be preserved by wrapping freshly picked khat in banana leaves, and then used dried.1

Effects of khat

There is no safe level of drug use. Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.

Khat affects everyone differently, based on:

  • size, weight and health
  • whether the person is used to taking it
  • whether other drugs are taken around the same time
  • the amount taken.

Short term effects may include:

  • increased talkativeness
  • feeling energetic and social
  • alertness and improved concentration
  • faster heartbeat and breathing
  • slightly higher temperature and blood pressure
  • reduced appetite.1-3

Long-term effects

Regular use of khat may eventually cause:

  • worsening of existing mental health problems
  • sleep-related issues
  • liver disease
  • fertility problems, such as impotence and lower sperm count
  • digestive problems such as constipation
  • sore, inflamed mouth
  • psychological dependence
  • mouth cancer.1-3


Khat appears to pose a relatively low risk for dependence, but withdrawal symptoms may be experienced if someone stops using khat after they have been using it regularly.

Symptoms may include:

  • mild depression
  • lower blood pressure
  • tiredness.1, 2
