Concurrent Use of Cigarettes and Smokeless Tobacco in Minnesota

Cigarette smokers are being encouraged to use smokeless tobacco (SLT) in locations where smoking is banned. We examined state-wide data from Minnesota to measure changes over time in the use of SLT and concurrent use of cigarettes and SLT. The Minnesota Adult Tobacco Survey was conducted four times between 1999 and 2010 and has provided state-wide estimates of cigarette smoking, SLT use and concurrent use of SLT by smokers. The prevalence of SLT was essentially unchanged through 2007, then increased significantly between 2007 and 2010 (3.1% versus 4.3%,P<0.05). Similarly, the prevalence of cigarette smokers who reported using SLT was stable then increased between 2007 and 2010 (4.4% versus 9.6%,P<0.05). The finding of higher SLT use by smokers could indicate that smokers in Minnesota are in an experimental phase of testing alternative products as they adjust to recent public policies restricting smoking in public places. The findings are suggestive that some Minnesota smokers are switching to concurrent use of cigarettes and SLT. Future surveillance reports will be necessary to confirm the results.

BackgroundJapan is the leading market for heated tobacco products (HTPs). We assessed the latest prevalence of HTP use including novel products (Ploom S, glo sens, and Pulze).MethodsData were obtained from an internet-based, self-reported survey conducted during February-March 2020 with individuals aged 15–74 years in Japan(n=9044). Prevalence of current (past 30-day) HTP use and cigarette smoking was computed. Poison regression analysis was conducted to examine predictors of HTP use among current cigarette smokers (n=1478). All analyses were weighted to account for selection bias in the internet survey using a nationally representative sample of Japanese population.ResultsIn 2020, prevalence of current HTP use and cigarette smoking was 10.9% and 25.9% in Japan, respectively. The most commonly used HTP brand was IQOS (5.7%) followed by Ploom TECH/Ploom TECH+ (5.4%) and glo (2.6%). Use of Ploom S, glo sens and Pulze was 1.6%, 0.8% and 0.6%, respectively. Among current cigarette smokers, 34.9% of those who were interested in quitting smoking and 30.5% of those who were not interested in quitting reported concurrent use of HTP, respectively (difference not significant). Cigarette smokers who reported having multiple chronic conditions (aPR=2.31), alcohol consumption (aPR=2.07), and e-cigarette use (aPR=1.88) were more likely to use an HTP compared to those who did not report such characteristics.ConclusionsHTP use remained prevalent in Japan. One in three current cigarette smokers used HTPs regardless of whether they were interested inquitting smoking. Continuedsurveillance is important to inform national and global tobaccocontrol strategies.

Illicit Substances

A questionnaire relating to cigarette smoking behavior and use of other substances was administered to 863 college students in the state of Oregon. Results indicated that there was not a significant difference between cigarette smokers and non-smokers with regard to use of smokeless tobacco, alcohol consumption, or marijuana use. There was, however, a significant difference in the use of other illicit substances when comparing cigarette smokers and non-smokers. Cigarette smokers were much more likely to use illicit substances on an occasional or regular basis than were non-smokers. Smokeless tobacco users who indicated that they consumed alcohol and used marijuana and other illicit substances were more likely to consume more alcohol on a weekly basis than non-users. They were also more likely to use marijuana and other illicit substances on an occasional and regular basis.

ObjectiveThe current study examined indicators of dependence among youth cigarette smokers and e-cigarette users in Canada, England and the USA, including changes between 2017 and 2019.MethodsData are from repeated cross-sectional online surveys conducted in 2017, 2018 and 2019 with national samples of youth aged 16–19 years, in Canada (n=12 018), England (n=11 362) and the USA (n=12 110). Measures included perceived addiction to cigarettes/e-cigarettes, frequency of experiencing strong urges to smoke/use an e-cigarette, plans to quit smoking/using e-cigarettes and past attempts to quit. Logistic regression models were fitted to examine differences between countries and changes over time.ResultsThe proportion of ever-users who vaped frequently was significantly higher in 2019 compared with 2017 for all outcomes in each country. Between 2017 and 2019, the proportion of past 30-day vapers reporting strong urges to vape on most days or more often increased in each country (Canada: 35.3%, adjusted OR (AOR) 1.69, 95% CI 1.20 to 2.38; England: 32.8%, AOR 1.55, 1.08 to 2.23; USA: 46.1%, AOR 1.88, 1.41 to 2.50), along with perceptions of being ‘a little’ or ‘very addicted’ to e-cigarettes (Canada: 48.3%, AOR 1.99, 1.44 to 2.75; England: 40.1%, AOR 1.44, 1.03 to 2.01; USA: 53.1%, AOR 1.99, 1.50 to 2.63). Indicators of dependence among smokers were consistently greater than e-cigarette users, although differences had narrowed by 2019, particularly in Canada and the USA.ConclusionsPrevalence of dependence symptoms among young e-cigarette users increased between 2017 and 2019, more so in Canada and the USA compared with England. Dependence symptom prevalence was lower for e-cigarettes than smoking; however, the gap has narrowed over time.

Abstract Background Tobacco uptake in adolescents is associated with a range of predictors. We examined the predictors of cigarette smoking, smokeless tobacco (ST) consumption and use of both ST and cigarettes among adolescents in four South Asian countries. Methods We analysed the Global Youth Tobacco Surveys (GYTS) data for Bangladesh (2013), India (2009), Pakistan (2013), and Sri-Lanka (2015), using multinomial regression to examine associations between several predictors and tobacco use. Results Data from 23,681 adolescents were analyzed. Overall, 82.8% of the study population were between 13 and 15 years and 52.7% were girls, 2% were cigarette smokers, 6.5% were ST users and 1.1% used both ST and cigarettes, in the past 30-days. Exposure to smoking in public places was associated with past 30-days smoking (RRR 5.59, 95%CI 4.28-7.28), ST use (RRR 2.07, 95%CI 1.84-2.32) and use of both ST and cigarettes (RRR 11.42, 95%CI 7.44-17.54). Exposure to tobacco use in electronic media and being offered free tobacco products were associated with all forms of tobacco use. Shopkeepers’ refusal to sell cigarettes protected adolescents from smoking (RRR 0.47, 95%CI 0.36-0.63) and ST use (RRR 0.65, 95%CI 0.45-0.95). However, exposure to anti-tobacco mass media messages was not protective for any form of tobacco use. Adolescents taught at school about harmful effects of tobacco were less likely to use ST; no evidence of this association was observed for smoking. Conclusion The associations between tobacco use and pro-tobacco factors were strong but the associations with anti-tobacco factors lacked strength and consistency in this study population.

BackgroundThe concurrent use of cigarettes with other tobacco products, such as smokeless tobacco (SLT), is increasingly common. Extant work with cigarette smokers who also use SLT is based heavily on retrospective reports and between-group comparisons. The purpose of this study was to assess prospectively the patterns of dual users’ product use and nicotine exposure on days when cigarettes were smoked exclusively (single use) versus concurrently with SLT (dual use).DesignForty-six dual cigarette-SLT users recorded their product use in real time via ecological momentary assessment for a 2-week longitudinal design. They responded to questions about situational factors (eg, location, mood) using this same diary, and collected saliva samples each night for later cotinine measurement. At the end of this 2-week period, users reported on their reasons for and beliefs about SLT use.ResultsCotinine levels were significantly higher on dual versus single use days (mean±SEM=374.48±41.08 ng/mL vs 300.17±28.13 ng/mL, respectively; p<0.01), and the number of cigarettes logged was higher on dual versus single use days (11.13±0.98 vs 9.13±1.11, respectively; p<0.01). Product use was distinguished by situational factors, with the strongest predictor being location of use. Moreover, the most common reason for initiating (56.52%) and continuing (67.39%) SLT use was to circumvent indoor smoking restrictions.ConclusionsResults support the idea of product supplementation rather than replacement among this convenience sample of dual users. For smokers whose primary motivation for SLT use involves situations where they would otherwise be tobacco free, the potential benefits of clean indoor air laws may be diminished.

Abstract. Summary: Background: We aimed at estimating the agreement between the Medicap® (photo-optical) and Radiometer® (electro-chemical) sensors during exercise transcutaneous oxygen pressure (tcpO2) tests. Our hypothesis was that although absolute starting values (tcpO2rest: mean over 2 minutes) might be different, tcpO2-changes over time and the minimal value of the decrease from rest of oxygen pressure (DROPmin) results at exercise shall be concordant between the two systems. Patients and methods: Forty seven patients with arterial claudication (65 + / - 7 years) performed a treadmill test with 5 probes each of the electro-chemical and photo-optical devices simultaneously, one of each system on the chest, on each buttock and on each calf. Results: Seventeen Medicap® probes disconnected during the tests. tcpO2rest and DROPmin values were higher with Medicap® than with Radiometer®, by 13.7 + / - 17.1 mm Hg and 3.4 + / - 11.7 mm Hg, respectively. Despite the differences in absolute starting values, changes over time were similar between the two systems. The concordance between the two systems was approximately 70 % for classification of test results from DROPmin. Conclusions: Photo-optical sensors are promising alternatives to electro-chemical sensors for exercise oximetry, provided that miniaturisation and weight reduction of the new sensors are possible.
