Reverse smoking is a unique style of tobacco use in which the smoker places the lit end of a chutta into his or her mouth while smoking and then inhales the smoke from the lit end. The purpose of this scoping review is to explore reverse smoking and identify its effects among Indian reverse smokers. Literature search was conducted using PubMed, PubMed Central, Embase, and CINAHL Plus. Boolean operators AND/OR was used with the search terms. Search was limited to the original research articles, English language articles, and full-text articles. Finally seven original articles were selected for the scoping review. The studies were conducted between 1971 and 2016, where more studies were identified in the 21st century (2002–2016). Four themes emerged from the data analysis. The first themes explore the palatal mucosal changes in reverse smokers; the second theme presents carcinoma and reverse smoking; third theme focuses on effects of keratinization on detection of epithelial atypia, and lastly, the fourth theme focuses on reverse smoking and psychosocial factors. Reverse smokers are more likely to develop precancerous palatal alterations and squamous cell carcinoma of the palate. To make healthy choices, a strong focus on health promotion is required, which includes initiatives that emphasize the need of educating individuals about disease risks.

Introduction: Smoking is a hazardous habit which causes definite changes in the oral cavity, consequently there exist changes in the mucosa when subjected to smoking. Palatal mucosa is first to be affected. The present study determines the palatal status in reverse smokers and conventional smokers. Aim: To study and compare the clinical, cytological and histopathological changes in palatal mucosa among reverse and conventional smokers. Materials and Methods: Study sample was categorized into two groups. Group 1 comprised of 20 subjects with the habit of reverse smoking and Group 2 comprised of 20 subjects with the habit of conventional smoking. Initially, clinical appearance of the palatal mucosa was recorded, followed by a cytological smear and biopsy of the involved area among all the subjects. The findings were studied clinically, the specimens were analysed cytologically and histopathologically, and compared among the two groups. Results: The severity of clinical changes of the palatal mucosa among reverse smokers was statistically significant when compared to those of conventional smokers. There was no statistically significant difference observed in cytological staging between the groups with a p-value of 0.35. The histopathological changes in both the groups showed a significant difference with a p-value of 0.02. A significant positive correlation was observed between the clinical appearance, and cytological, histopathological changes. Conclusion: Profound clinically aggressive changes were observed in group I compared to group II. Severity of dysplastic changes have been detected in few subjects through histopathological examination irrespective of no prominent clinical and cytological changes observed among the two groups.

Objectives: Reverse smoking is a peculiar form of smoking in which the smoker puts the lit end of the cigarette into the mouth and then inhales the smoke. There may be many predisposing factors that influence an individual to cultivate this habit, of which psychosocial habits could be the predominating factor. Hence, the present study was undertaken to evaluate the psychosocial factors that influence an individual to undertake this peculiar habit of reverse smoking. Materials and Methods: A total of 128 habitual reverse smokers were included in the study, out of which 121 were females and 7 were males. A pretested open-ended questionnaire was used for data collection. Data was collected by direct interview method. Snowball sampling technique was employed in collecting the information regarding regular reverse smokers. Interviews were continued until new information did not provide further insights into the categories. The people who could not understand verbal commands and questions and who did not give an informed consent were excluded from the study. Statistical analysis was done using MS Office Excel using Chi-square test of Goodness of fit. Results: In contrast to the conventional smokers, various new reasons were identified for starting reverse smoking, of which the most important was that they had learned this habit from their mothers. This was followed by other reasons such as peer pressure, friendship, and cold climatic conditions. Conclusion: This study provided an insight into the various factors that could influence an individual to take up this peculiar habit of reverse smoking. [ABSTRACT FROM AUTHOR]
