Lichenoid reactions occur exclusively in people who chew tobacco, areca nut, or both, in raw or any manufactured or processed form. The lesion is described as a lichen-planus-like lesion and is termed as quid-induced lichenoid reaction (QILR). In this cross-sectional study, amongst 935 quid consumers, 82 patients were diagnosed with QILR and it was seen that 65 patients used processed forms of tobacco and areca nut. Thereby, it could be concluded that QILR might occur because of flavors used in processing of tobacco and areca nut.
