Khat (pronounced cot ) is a stimulant drug derived from a shrub (Catha edulis) that is native to East Africa and southern Arabia. The khat plant itself is not scheduled under the Controlled Substances Act; however,because one of its chemical constituents,cathinone,is a Schedule I drug,the Federal Government considers its use illegal.
