To the annoyance ofnon-smokers, smoking is still allowed in many public places, such as restaurants and offices. This study serves, firstly, to provide an overview of the results of research on the dangers ofsmoking, nicotine addiction and passive smoking. Secondly, a self-comple­ tion questionnaire has been applied to a sample ofstudents at eight technikons in South Africa. The questionnaire was designed to investigate the prevalence of smoking among the different population groups and genders to reveal some of the pattems of smoking of students, the factors influencing students' smoking status and to test students' beliefs, opinions and attitudes regarding smoking. The third objective ofthe study is to develop a theory on cigarette smoking and to propose anti-smoking measures at technikons. Researchers have produced conclusive proof that cigarette smoking is the cause of cancer, respiratory and heart disease and other diseases. Smoking maims and kills millions ofpeople around the world annually and threatens the health ofunbom babies and non-smokers, especially children. Tobacco companies apply the most sophistic­ ated promotion techniques to persuade people to smoke and teenagers and certain other sectors' of the population are targeted by these activities. A study of nicotine addiction reveals that the need for this substance becomes as strong as any of man's basic physiological needs, such as those for food and water. This makes it very difficult, ifnot impossible, for many smokers to give up smoking. A multi-pronged strategy to combat smoking at education institutions is proposed, which includes health education and the banning of smoking on campuses.

    ADDRESSING THE TOBACCO EPIDEMIC IN LOW AND MIDDLE INCOME COUNTRIES: BEST PRACTICES THAT REDUCE THE IMPACT OF TOBACCO ADVERTISING, PROMOTION AND SPONSORSHIP By LORNA MCLEOD ENGLISH (Under the Direction of Joel Lee) ABSTRACT Tobacco use is leading cause of preventable death in the world. The World Health Organization (WHO) projects that by 2030 tobacco use will kill over 8 million people annually. Eighty percent of the world’s smokers now live in low and middle income countries (LMIC) compared to 20 percent in developed countries. A primary reason for increased smoking in these countries is the tobacco industry’s targeted and aggressive marketing of cigarettes; billions of dollars are spent annually on tobacco advertising, promotion and sponsorship (TAPS). In 2003, the WHO negotiated the Framework Convention on Tobacco Control (FCTC) to prevent the death and disease associated with tobacco use. The FCTC treaty calls for countries to enact comprehensive policies that ban TAPS and inform their populations about dangers of tobacco use. The treaty is founded on proven interventions that countries can implement to protect their population from the epidemic. The objective of this research is to examine tobacco-related policies in LMIC to assess their impact on smoking behaviors. The first study reviewed the impact of TAPS exposure and anti-TAPS policies on students’ smoking behavior in African LMIC. The second study examined the impact of anti-TAPS policies and counter-tobacco messages on male smoking behavior in Thailand and Turkey. The findings suggest that there is an association between TAPS exposure and increased smoking and susceptibility in the youth studied.

Khana, V. Hiraa and F. Haffejeea* a Department of Basic Medical Sciences, Durban University of Technology, Durban, South Africa *Corresponding author, emails: [email protected], [email protected] Background: Smoking among adolescents is high. In order to curb the habit, restrictions on use of tobacco products in public places were implemented in South Africa. This study aimed to explore students’ perceptions of whether the implementation of smoking restrictions and no-smoking signs have had any effects on smoking behaviours on campus. Methods: A quantitative cross-sectional study was conducted amongst university students, who completed a self-administered questionnaire. Results: Students were aware that smoking causes disease and that second-hand smoke is dangerous. The majority were pleased that there was a smoking regulation in effect, but disagreed that it created a healthier atmosphere. Many would like a total ban enforced in restaurants, clubs, bars and university campuses. They felt that there were insufficient non-smoking signs in public areas. Many smokers stated that they ignored regulations and only a minority stated that the policy encouraged smokers to quit.

This study investigates non-smokers’ exposure to second-hand smoke (SHS) in workplaces, homes, cafés/restaurants, and shebeens (local bars) using data from the 2017 South African Social Attitude Survey. Factors associated with any level of exposure were explored using multiple-variable-adjusted logistic regression analysis. The sample of 3063 participants (16+ years old), comprised 51.7% females and 78.5% Black Africans. The current smoking prevalence from this study was 21.5%. About 47% of non-smokers reported exposure to SHS in at least one location. Females were significantly less likely to be exposed to SHS in all locations except at home compared to males.

We report on (1) the historical context of tobacco use among Ojibwe Indians; (2) risk factors that facilitate use: peer/parental smoking, acceptability/ availability of cigarettes; (3) cessation efforts/ inhibiting factors for cessation: smoking while pregnant, smoking to reduce stress , beliefs that cessation leads to debilitating withdrawals; and (4) protective factors that inhibit smoking initiation/ use: negative health effects of smoking, parental and familial smoking behaviors, encouragement from youth to quit smoking, positive health benefits, “cold turkey” quitting, prohibition of smoking in tribal buildings/homes. Smoking is prevalent, but protective behaviors are evident and can assist in designing culturally sensitive prevention, intervention and cessation programs.

To assess current menthol application levels in the U.S. cigarette market, menthol levels in cigarettes labeled or not labeled to contain menthol was determined for a variety of contemporary domestic cigarette products. Method—We measured the menthol content of 45whole cigarettes using a validated gas chromatography/mass spectrometry method (GC/MS). Results—In 23 cigarette brands labeled as menthol products, the menthol levels of the whole cigarette ranged from 2.9 to 19.6 mg/cigarette, with three products having higher levels of menthol relative to the other menthol products. The menthol levels for 22 cigarette products not labeled to contain menthol ranged from 0.002 to 0.07 mg/cigarette.

    Public Disclosure Authorized Poverty & Equity Global Practice Working Paper 146 LONG-RUN IMPACTS OF INCREASING TOBACCO Public Disclosure Authorized TAXES EVIDENCE FROM SOUTH AFRICA Public Disclosure Authorized Alan Fuchs Giselle Del Carmen Alfred Kechia Mukong Public Disclosure Authorized March 2018 Poverty & Equity Global Practice Working Paper 146 ABSTRACT Tobacco taxes are considered an effective policy tool to reduce tobacco consumption and produce long-run benefits that outweigh the costs associated with a price increase. Through this policy, some of the most adverse effects and economic costs of smoking can be reduced, including shorter life expectancy, higher medical expenses, added years of disability among smokers, and the effects of secondhand smoke. Nonetheless, tobacco taxes are often considered regressive because low-income households tend to allocate a larger share of their budgets to purchasing tobacco products. This paper uses an extended cost-benefit analysis to estimate the distributional effect of tobacco taxes on household welfare in South Africa. The analysis considers the effect on household income through an increase in tobacco prices, changes in medical expenses, and the prolongation of working years. The results indicate that a rise in tobacco prices initially generates negative income variations across all groups in the population. If benefits through lower medical expenses and an expansion in working years are considered, the negative effect is reduced, particularly in medium- and upper- bound elasticities. Consequently, the aggregate net effect is progressive and benefits the bottom deciles more than the richer ones. Overall, tobacco tax increases exert a small, but positive effect in the presence of low conditional tobacco price elasticity.
