14.4.1  Immediate effects of khat use

People chew khat because they believe that, like tobacco, it improves their concentration. During and immediately after chewing khat, people state they feel euphoric and wakeful, and have increased energy. They are also likely to have a decreased appetite (and are consequently often underweight) and an increased body temperature. Khat can also provoke paranoia and aggressiveness.
