Abstract: This paper reports on an investigation of the cytotoxic and genotoxic potential of khat extract using a human T lymphoblastoid cell line (CEM). Exponentially growing CEM cells were cultured for 12 h in the presence of khat extract (0-2000 μg ml^-¹). Statistically significant, dose-dependent increases in; CEM cell death at dose (> 400 μg ml^-¹), in DNA damage at dose (>200 μg ml^-¹) and in micronuclei frequency, at dose (>200 μg ml^-¹) were observed. The genetic damage effects of khat extract on human cell line observed in this study could serve as a major contribution towards the understanding and creating of awareness of an increased risk of cancer amongst long-term khat consumers.
