The smoking habits of 324 villagers of Uppada, East Godavari District, A.P., India, and their effect on the palatal mucosa leading to cancer, were studied. The frequency of reverse smoking (i.e., smoking with the lighted end inside the mouth) was 6.23 times higher in females than in males. The frequency of preleukoplakia was 2.26 times higher, that of leukoplakia was 13.84 times higher, and that of stomatitis nicotina was 7.13 times higher in reverse smokers than in regular smokers. These frequencies are lower compared to earlier studies done in the 60's and 70's in the districts of Visakhapatnam and Srikakulam.
对印度安得拉邦东戈达瓦里区乌帕达的324名村民的吸烟习惯及其对导致癌症的腭黏膜的影响进行了研究。女性反向吸烟（即点燃的一端在口腔内吸烟）的频率比男性高6.23倍。反向吸烟者的白斑前期频率比普通吸烟者高2.26倍，白斑频率高13.84倍，烟碱性口炎频率高7.13倍。与60年代和70年代在维沙卡帕特南和斯里卡库拉姆地区进行的早期研究相比，这些频率较低。
