Khat chewing is a deep-rooted habit in Yemen. It has many
negative impacts on different body systems. The spread of khat chewing
among adult males in Yemeni society needs special attention. Cathinone
and cathine are the most stimulants of khat ing
redients. Other ingredients
could have other implication such as gastrointestinal carcinogenic tannins.
the aim of this study is to Investigate chronic khatchewing
effects on oral mucosa and the role of concurrent smoking.
Chewing Qat is a common habit in the Yemen society.
Various studies demonstrated clear effects of this habit on the
Yemen society, in general, and the systemic organs of the
human body in particular. The absence of studies about the
effects of chewing Qat on teeth, supporting tissues, and oral
mucosa was the major motive for this study.
