A qualitative study of attitudes to and perceptions of betel quid consumption and its oral health implications in Taiwan.

Objectives: Betel quid (BQ) chewing is extremely prominent in South and Southeast Asia because it considered by users to be of social, cultural and religious importance. BQ chewing has been recognized as a risk factor for oral premalignant lesions and oral cancer. Because BQ chewing has become a severe health risk in Taiwan, the development of prevention and cessation programmes is essential.
