Khat consumption induces mild euphoria and excitement, similar to that conferred by strong coffee. Individuals become very talkative under the influence of the plant. Animal testing has shown that khat causes an increase in motoric activity. The effects of oral administration of cathinone occur more rapidly than the effects of amphetamine pills; roughly 15 minutes as compared to 30 minutes in amphetamine. Khat can induce manic behaviours and hyperactivity, similar in effects to those produced by amphetamine.
