What can research evidence tell us about effect of khat on health and socio-economy? Rapid evidence review

Abstract

Khat chewing was highly associated with elevated Blood pressure (BP) and heart rate which are established risk factors for cardiovascular diseases.  Khat induces a very consistent and reproducible type of cell death in humans but evidence has not been found on the direct relationship between Khat and cancer. Sub-chronic exposure to khat affects short-term memory depending on the duration of exposure. However, it does not have any effect on long-term memory. But, it induces neurobehavioral changes. 

There are high socioeconomic implications of Khat chewing including big money spending on buying Khat, getting forced into credit and money borrowing. The social burden of Khat chewing goes beyond the Khat chewers affecting women, children, families and communities at large.

Even though the qualities of evidence included in this review range from inconclusive, low and medium; it can be considered that Khat chewing results in varieties of health consequences. Therefore, this review is thought to be sufficient to regulate Khat from its production to consumption. The social and economic effects of khat consumption on individuals and households need further research.
