Alcohol Use Among Khat (Catha) Chewers in Kenya

British Journal of Addiction, 1987
SummaryAmong one hundred randomly selected outpatients at the Meru District Hospital in Kenya, 29 (28 men and 1 woman) were Khat chewers. Six of these were ‘heavy’ and 23 ‘moderate’ users. Twenty out of 29 Khat chewers also used alcohol heavily. Consequences of this joint misuse of two potentially addictive drugs are discussed.

Effects of the active constituents of Catha edulis on the neuromuscular junction

Neuropharmacology, 1987
(-)-Cathinone and d-norpseudoephedrine (DNE) in the dose range 0.2-1.2 mg/ml produced a reduction in contractions of skeletal muscle, evoked by direct and indirect electrical stimulation and antagonised the facilitatory action of physostigmine on the neuromuscular junction; but failed to antagonise a partial blockade induced by d-tubocurarine (dTb) as ...

Fluoride content in khat (Catha edulis) chewing leaves

Archives of Oral Biology, 2000
Khat (qat) leaves are chewed for their psychostimulative effects; there is an unconfirmed suggestion that they contain a high concentration of fluoride (F). Khat samples from Yemen were suspended in deionized water, spun, and the supernatants exposed to a chelator that decomplexes F, which was assayed with an F(-)-electrode coupled to an ion analyser ...

The pharmacology of psychoactive alkaloids from Ephedra and Catha

Journal of Ethnopharmacology, 1991
Ever since the introduction of the alkaloid ephedrine as an anti-asthmatic, the CNS stimulatory effects of this sympathomimetic have been a problem in therapy. Indeed, the use of ephedrine is not only limited by its cardiovascular effects, but also by the occurrence of insomnia, restlessness and anxiety.

Determination of chiral cathinone in fresh samples of Catha edulis

Forensic Science International, 2020
The main psychoactive compound in Khat is cathinone which consists of two enantiomers, S-(-)-cathinone being more stimulant than its R antipode. This study aimed to the enantioseparation and determination of these two stereoisomers in different parts of fresh Catha edulis.
