Tobacco is a national strategic commodity that contributes to state revenues and employment. The purpose of this research is to analyze tobacco farming income and to analyze farmers' perceptions regarding the policy of increasing excise tariffs on processed tobacco/cigarette taxes. The research method used is qualitative analysis with a descriptive analysis approach. The research was conducted in Suralaga District, East Lombok Regency. Suralaga sub-district was chosen because it is a sub-district that mostly cultivates tobacco commodities. Respondents used in this study were 30 respondent farmers. 15 farmers live in Bagik Payung Village, some 15 farmers live in Waringin Village. Both villages are tobacco farmers and are located in Suralaga District, East Lombok Regency. The results showed that tobacco farming in East Lombok Regency was declared feasible because based on the analysis, the farming experienced an income (profit) of Rp. 8,045,942/hectare/planting season with a farming feasibility level of 1.70> 1 (feasible category). Most farmers have the perception that the policy of increasing tobacco excise/cigarette tax aims to help the national economy through increasing state revenues, not to control the level of cigarette consumption. The local/central government has never socialized the increase in tobacco/cigarette excise. In addition, farmers also assume that the government has never provided assistance or compensation to farmers after the policy of increasing tobacco/cigarette excise. The increase in cigarette excise does not have a direct impact on the decline in the economic condition of farmers. The factors that have the most direct influence on farmers' income are uncertain weather conditions (climate change) and the determination of the selling price grade of tobacco harvests which is less transparent.

Abstract Background Tobacco smoking is considered as one of the lifestyles factors that influence the sperm DNA methylation and global sperm DNA methylation and that may affect the sperm phenotype. This study was performed to investigate whether tobacco cigarette heavy smoking influences sperm DNA methylation patterns and semen parameters and to determine whether there is an alteration in the transcription level of MAPK8IP3, GAA, ANXA2, PRRC2A, and PDE11A genes in heavy smokers compared to non-smokers. Thirty samples were subjected to 450K arrays as a screening study to assess the variation in sperm DNA methylation levels between heavy smokers and non-smokers. Five CpG sites have the highest difference in methylation levels (cg07869343, cg05813498, cg09785377, cg06833981, and cg02745784), which are located in the MAPK8IP3, GAA, ANXA2, PRRC2A, and PDE11A genes, respectively, and were selected for further analysis using deep bisulfite sequencing in 280 independent samples (120 proven non-smokers and 160 heavy smokers) with a mean age of 33.8 ± 8.4 years. The global sperm DNA methylation, sperm DNA fragmentation, and chromatin non-condensation were evaluated also. Results A significant increase was found in the methylation level at seven, three, and seventeen CpGs within the GAA, ANXA2, and MAPK8IP3 genes amplicon, respectively (P< 0.01) in heavy smokers compared to non-smokers. Additionally, a significant increase was found in the methylation levels at all CpGs within PRRC2A and PDE11A gene amplicon (P< 0.01). A significant increase was found in the level of sperm chromatin non-condensation, DNA fragmentation, and global DNA methylation (P < 0.001) in heavy smokers compared to non-smokers. Conclusion These results indicate that tobacco cigarette smoking can alter the DNA methylation level at several CpGs, the status of global DNA methylation, and transcription level of the following genes “MAPK8IP3, GAA, ANXA2, PRRC2A, and PDE11A” in human spermatozoa. These findings may affect negatively semen parameters and men’s fertility.

Abstract Background/Introduction Tobacco cigarette (TC) smoking acutely increases blood pressure and sympathetic nerve activity, whereas there are scarce data on the impact of electronic cigarette (EC). Purpose The aim of the study was to assess the acute effects of TC, EC and sham smoking on blood pressure, heart rate and sympathetic nervous system in healthy subjects. Methods We studied 12 normotensive male habitual smokers (mean age 33 years) free of cardiovascular disease. The study design was randomized and placebo controlled with 3 experimental sessions (sham smoking, tobacco cigarette smoking, and e-cigarette smoking) in random order, each session on a separate day. Subjects smoked 2 tobacco cigarettes containing 1.1 mg nicotine or simulate smoking (sham smoking) with the 2 cigarettes separated by 5 minutes. Additionally, participants smoked e-cigarettes for a period of 5 and 30 minutes. In all occasions, sympathetic drive was assessed by muscle sympathetic nerve activity (MSNA) (baroreflex-dependent) and skin sympathetic nerve activity (SSNA) (baroreflex-independent) based on established methodology (microneurography). Results After the first and second TC smoking, there was significant increase in mean arterial pressure (MAP) (by 6 and 8 mmHg, respectively, overall p&lt;0.001) and heart rate (by 8 and 12 beats/minute, respectively, overall p&lt;0.001) compared to baseline. Similarly, EC smoking at 5 and 30 minutes compared to baseline was accompanied by augmentation of MAP (by 6 and 10 mmHg, respectively, overall p&lt;0.001) and heart rate (by 5 and 9 beats/minute, respectively, overall p&lt;0.001). Sham smoking was accompanied by a reduction in MAP after the first and second cigarette compared to baseline (by 2 and 4 mmHg, respectively, p=0.001), whereas there was no significant difference in heart rate (p=NS). The first and second TC smoking was characterized by lower muscle MSNA (by 6 and 6 bursts/minute, respectively, overall p&lt;0.001) compared to baseline, whereas SSNA was increased (by 9 and 10 bursts/minute respectively, overall p&lt;0.001). Additionally, EC smoking at 5 and 30 minutes caused a decrease in MSNA (by 8 and 8 bursts/minute, respectively, overall p&lt;0.00) and an augmentation in SSNA (by 7 and 9 bursts per minute, respectively, overall p&lt;0.001) compared to baseline. Sham smoking had no significant effect on MSNA and SSNA (p=NS for both). Conclusions Sympathetic, pressor and heart rate unfavorable responses to EC smoking are similar to those elicited by TC in healthy subjects. Our findings provide novel insights into the negative impact of EC on cardiovascular system and support opinions recommending great caution concerning EC use.

Background: As e-cigarette popularity has increased, there is growing evidence to suggest that while they are highly likely to be considerably less harmful than cigarettes, their use is not free of risk to the user. There is therefore an ongoing need to characterise the chemical composition of e-cigarette aerosols, as a starting point in characterising risks associated with their use. This study examined the chemical complexity of aerosols generated by an e-cigarette containing one unflavored and three flavored e-liquids. A combination of targeted and untargeted chemical analysis approaches was used to examine the number of compounds comprising the aerosol. Contributions of e-liquid flavors to aerosol complexity were investigated, and the sources of other aerosol constituents sought. Emissions of 98 aerosol toxicants were quantified and compared to those in smoke from a reference tobacco cigarette generated under two different smoking regimes.Results: Combined untargeted and targeted aerosol analyses identified between 94 and 139 compounds in the flavored aerosols, compared with an estimated 72–79 in the unflavored aerosol. This is significantly less complex (by 1-2 orders of magnitude) than the reported composition of cigarette smoke. Combining both types of analysis identified 5–12 compounds over and above those found by untargeted analysis alone. Gravimetrically, 89–99% of the e-cigarette aerosol composition was composed of glycerol, propylene glycol, water and nicotine, and around 3% comprised other, more minor, constituents. Comparable data for the Ky3R4F reference tobacco cigarette pointed to 58–76% of cigarette smoke “tar” being composed of minor constituents. Levels of the targeted toxicants in the e-cigarette aerosols were significantly lower than those in cigarette smoke, with 68.5–&gt;99% reductions under ISO 3308 puffing conditions and 88.4–&gt;99% reductions under ISO 20778 (intense) conditions; reductions against the WHO TobReg 9 priority list were around 99%.Conclusion: These analyses showed that the e-cigarette aerosols contain fewer compounds and at significantly lower concentrations than cigarette smoke. The chemical diversity of an e-cigarette aerosol is strongly impacted by the choice of e-liquid ingredients.

Abstract Background This systematic review of prospective longitudinal primary studies sought to determine whether electronic cigarette (e-cigarette) use by teenagers who had never smoked conventional tobacco cigarettes (tobacco cigarettes) at baseline was associated with subsequently commencing tobacco cigarette smoking. Methods The review followed the principles of a systematic review and meta-analysis. A key word search identified peer-reviewed articles published between 1 January 2005 and 2 October 2019 from seven bibliographic databases and one search engine. Using pre-prepared inclusion/exclusion criteria two researchers independently screened abstracts, and subsequently, full text papers. Selected articles were quality assessed in duplicate. Data on study participants characteristics, exposure and outcome measures were recorded in an adapted Cochrane Data Extraction Form. Feasibility assessment was done to detect clinical heterogeneity and choose an approach to meta-analysis. Analysis comprised pairwise random effects meta-analyses, and sensitivity and subgroup analyses. Results From the 6619 studies identified, 14 one-off primary studies in 21 articles were suitable for inclusion. The participants ages ranged from 13 to 19 years and comprised teenagers based in Europe and North America. Nine of the 14 one-off studies, with follow-up periods between 4 and 24 months, met the criteria for inclusion in a meta-analysis of the association between ever use of e-cigarettes and subsequent initiation of tobacco cigarette use. Based on primary study adjusted odds ratios, our meta-analysis calculated a 4.06 (95% confidence interval (CI): 3.00–5.48, I2 68%, 9 primary studies) times higher odds of commencing tobacco cigarette smoking for teenagers who had ever used e-cigarettes at baseline, though the odds ratio were marginally lower (to 3.71 times odds, 95%CI: 2.83–4. 86, I2 35%, 4 primary studies) when only the four high-quality studies were analysed. Conclusion The systematic review found that e-cigarette use was associated with commencement of tobacco cigarette smoking among teenagers in Europe and North America, identifying an important health-related harm. Given the availability and usage of e-cigarettes, this study provides added support for urgent response by policymakers to stop their use by teenagers to decrease direct harms in this susceptible population group, as well as to conserve achievements in diminishing tobacco cigarette initiation.
