Effects.
The pharmacology of khat has been reviewed and its effects are characterized by a moderate degree of central nervous system (CNS) stimulation, resulting in a state of mild euphoria and excitement, often accompanied by talkativeness to excess. High doses may induce restlessness and sometimes manic behavior. Excessive consumption may lead to toxic psychosis. Khat produces ANOREXIA (loss of appetite) and constipation; it has sympathomimetic effects on the cardiovascular system. Dilation of the pupil and staring are indicative of the acute effect of khat. Habitual chewing is usually revealed by a brownish staining of the teeth.
The effects are very similar to those of AMPHETAMINE, and the difference between the two drugs is quantitative rather than qualitative. Accordingly, habitual khat use may give rise to psychic dependence, which usually is moderate but often persistent. The withdrawal symptoms after prolonged use are slight trembling, lethargy, mild depression, and recurrent bad dreams. Khat use by the habitué is often compulsive, with the necessary supplies obtained at least once a day, even at the expense of vital needs; in the countries where khat use is widespread, the socioeconomic consequences of the habit are considerable.
