Khat dependency and psychophysical symptoms among chewers in Jazan Region, Kingdom of Saudi Arabia

Abstract

Background. Khat chewing is highly prevalent in Africa, Yemen and Jazan region, southwest of Saudi Arabia. Most of Jazani Khat chewers consider khat session as a social activity and do not consider khat dependency. The aim of this study was to explore khat dependency and its relationship with the psychophysical symptoms among chewers. Methods. Cross-sectional study on seventy Saudi male khat chewers living in Jazan area. Psychological dependence to khat chewing was evaluated using the Severity of Dependency Scale (SDS). The participants filled in a self-administrated assisted structured questionnaire designed to collect data about their medical history, neurological symptoms, and their chewing behavior. Results. Half (52.2%) of khat chewers showed psychological dependency. Those having longer khat sessions (≥6 hours) were more liable for dependency. Physical and psychological symptoms were more prevalent among khat dependent chewers. Conclusions. khat has a psychological dependence effect that can be measured by the SDS, even in low doses and with irregular use. SDS scale is a useful tool to expect the burden of either physical or psychological symptoms on khat chewers.
