Processing Steps

Background: Qiwam (Kimam) is a liquid tobacco preparation consumed with paan. It is mostly consumed in southeast Asian region. Evidences suggest that it causes potentially malignant disorders (PMD), oral cancer (OC) and decreases sperm count. Qiwam was mentioned in earlier research publications, however details are not known. It is produced for self-consumption as well as for commercial purpose. Aim: To study in detail the ingredients and processing steps involved in the production of Qiwam. In addition, also study the adverse health implication of this smokeless tobacco product on humans. Methods: The information on qiwam was collected via literature search study, study tour to different geographical areas of India, where group discussions with the people involved in the production of qiwam, paan vendors and with community members of different age group were done. Results: Qiwam is prepared by the user for his/her own consumption or by industry for sale. Tobacco leaves and tobacco roots are boiled for several hours then soaked in water flavored with varied spices and additives. The resultant mixture is mashed, strained, and finally dried into a thick paste. It is consumed mostly with paan. Conclusion: Processing of qiwam is a complex and time taking process which involves various steps and components that may influence the carcinogenic property of the product. The different processing steps gives different taste and texture to the product. Qiwam increases the risk of cancer and hence needs to be banned or better avoided.

AbstractSmokeless tobacco (ST) products are used worldwide and are a major public health concern. In addition to harmful chemicals found in these products, microbes found in ST products are believed to be responsible for generating harmful tobacco-specific nitrosamines (TSNAs), the most abundant carcinogens in ST. These microbes also contribute endotoxins and other pro-inflammatory components. A greater understanding of the microbial constituents in these products is sought in order to potentially link select design aspects or manufacturing processes to avoidable increases in harmful constituents. Previous studies looked primarily at bacterial constituents and had not differentiated between viable vs nonviable organisms, so in this study, we sought to use a dual metatranscriptomic and metagenomic analysis to see if differences exist. Using high-throughput sequencing, we observed that there were differences in taxonomic abundances between the metagenome and metatranscriptome, and in the metatranscriptome, we also observed an abundance of plant virus RNA not previously reported in DNA-only studies. We also found in the product tested, that there were no viable bacteria capable of metabolizing nitrate to nitrite. Therefore, the product tested would not be likely to increase TSNAs during shelf storage. We tested only a single product to date using the strategy presented here, but succeeded in demonstrating the value of using of these methods in tobacco products. These results present novel findings from the first combined metagenome and metatranscriptome of a commercial tobacco product.

The Impact

Background: Smoking and smokeless tobacco use is the major cause of death and disease in South Asia, the use of gutka has surpassed that of smoking in this region thus, acting as a major contributor to oral and esophageal cancer especially in the younger population. Authors have designed this study to explore the knowledge, apptitude and practice regarding smoking and gutka use in a lower socio-economic cohort and observe the impact of education, income and type of profession on the users.Methods: This cross sectional descriptive survey is conducted in Creek General Hospital, Korangi, Karachi. The study design is non-probability convenience. A questionnaire is used to quantify the frequency of smoking-related knowledge-attitude-practice, knowledge and attitude about tobacco-related disease and, smoking cessation-related thoughts and practice. Data is analysed in SPSS 16.Results: A total of 250 subjects participated in this descriptive study, 133 subjects (22% females and 62.6% males) were found addicted to smoking or smokeless tobacco product with stress, seeking pleasure and peer pressure being the most convincing factor to initiate their habit.90% of the users want to stop using the substance of abuse and 80 have at least once tried to quit the habit.Conclusions: This study shows a direct relationship between level of education and socioeconomic status with use of addictive substance. It also resulted in identifying the desire to quit in our cohort and need for formulating a plan specifically for the target population to focus not only to remove the cause, but also to empower them to take responsibility for their own well being.
