Cathinone, or benzoylethanamine (marketed as hagigat in Israel), is a monoamine alkaloid found in the shrub Catha edulis (khat) and is chemically similar to ephedrine, cathine and other amphetamines. Cathinone induces the release of dopamine from striatal preparations that are prelabelled either with dopamine or its precursors. It is probably the main contributor to the stimulant effect of Catha edulis. Cathinone differs from many other amphetamines in that it has a ketone functional group. Other amphetamines that share this structure include the antidepressant bupropion and the stimulant methcathinone, among others.

Internationally, cathinone is a Schedule I drug under the Convention on Psychotropic Substances. Circa 1993, the DEA added cathinone to the Controlled Substances Act's Schedule I.

The sale of khat is legal in Israel (although synthetic cathinone is not), and also in Oman, in Yemen, in the United Kingdom and in the Horn of Africa.

Cathinone is structurally related to methcathinone, in much the same way as amphetamine is related to methamphetamine. Cathinone differs from amphetamine by possessing a ketone oxygen atom (C=O) on the β (beta) position of the side chain. The corresponding alcohol compound cathine is a less powerful stimulant. The biophysiological conversion from cathinone to cathine is to blame for the depotentiation of khat leaves over time. Fresh leaves have a greater ratio of cathinone to cathine than dried ones, therefore having more psychoactive effects.
