Reverse smoking

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]
