Reverse smoking is a kind of smoking where the burnt end of a hand rolled tobacco leaf is put in the mouth rather than the unlit end of the cigar. [1] It is practiced in some parts of Andhra Pradesh, India, Lusaka, Zambia and the Philippines. While conventional smoking is more prevalent among men, [2] studies suggest that reverse smoking is a more common among women than men. [3] [4] Reverse smoking is considered to be a risk factor for oral cancer. [5]
Reverse smoking may cause a pre-malignant version of Stomatitis nicotina, [6] also called "smoker's palate", characterized by melanin depigmentation and epithelial thinning. [7] [8]
