Revolutionary case against tobacco use in Nigeria

-Alexander Chiejina

…Tobacco control bill yet to be passed by National Assembly Without a doubt, the health, economic, social, and environmental consequences of tobacco use in Nigeria and the continent are enormous.
Little wonder the World Health Organisation (WHO) recently revealed that African countries are experiencing a 4.3 percent annual increase in the rate of tobacco consumption. This has resulted in an upsurge of lung cancer and related cases which are now prevalent in the society.
It was against this background that experts, at a recent training for health reporters on cancer reporting organised by Journalists Advocacy on Tobacco and Health held recently at Ogba, Lagos urged that the trend should be checked.
Speaking at the event, Akinbode Oluwafemi, programme manager, Environmental Rights Action/Friends of the Earth (FoEN), noted that tobacco smoking is responsible for more than 85 percent of lung cancers. This, he explained, is because smoking-related cancer accounts for 30 percent of cancer-related deaths, adding that renowned journalists in the country like Steve Kadiri, Yinka Craig, Momoh Kubanji, Tina Onwudinwe and Beko Ransome Kuti lost their lives due to the health hazards associated with the consumption of cigarettes.
“Research findings have it that there are about 599 approved additives in a stick of cigarette. However, cigarette smoke has been proven to contain over 4000 toxic and cancer causing chemicals; carbon monoxide, nitrogen oxides, hydrogen cyanide, ammonia, to name but a few,” Oluwafemi disclosed. According to him, cigarette advertising, promotion and sponsorship such as ‘Welcome to London, cool feeling’ have made cigarette smoking appealing to a lot of youths, without some of these tobacco companies apprising the public of dangers associated with smoking.
Lending his view, Tosin Orogun, programme manager, Communications and IT, Africa Tobacco Control Regional Initiative (ATCRI), declared that the rise in cigarette smoking in the society is traceable to tobacco companies which increasingly target the developing world as barriers rise and smoking rates fall in more mature markets. “What we (ATCRI) have been trying to do is to facilitate the adoption, implementation and enforcement of effective in-country tobacco control policies, legislation and programs in Nigeria and across the continent,”
Orogun revealed. Already, a 2009 report on the implementation of smoke-free environments aimed at combating Global Tobacco Epidemic shows that five more countries (Djibouti, Egypt, Islamic Republic of Iran, Malaysia and Mauritius) meet the best practices for health warnings on cigarette packages. Three other countries (Israel, Romania and the United Arab Emirates), meanwhile, offer comprehensive help in the drive to eradicate tobacco consumption. In the same vein, only Panama has joined the small group of countries that ban all forms of tobacco advertising, promotion and sponsorship, even as more than 90 percent of people lack protection from tobacco industry marketing. Six more countries (Czech Republic, Estonia, Fiji, Finland, the Netherlands and Seychelles) have levied tobacco taxes higher than 75 percent of retail price.
Lastly, of the world’s 100 most populous cities, 22 are smoke-free. Sadly, though, reports from the recently concluded media summit hosted by the American Cancer Society ahead of the AORTIC cancer in Africa, stated that 55 percent of school students are not aware that secondhand smoke is harmful to health, and only 1 percent of Nigeria’s population are protected by strong smoke-free laws. This lays bare the fact that if nothing is done to hastily check public smoking in the country, the rising figures of cancer and other non-communicable diseases may remain.
The bill to ban cigarette smoking in public places which had its public hearing before the National Assembly 19 July this year should quickly be passed into law. A part of the bill which seeks to protect people from secondhand smoke, raise taxes on tobacco, enforce a level of ban on tobacco advertising, promotion and sponsorship would in the long run, save Nigerians from self- inducing cancer types.

Smoking cessation offers measurable benefits for asthmatic patients

The Medical News


Asthmatic smokers may be able to reverse some of the damage to their lungs that exacerbates asthmatic symptoms just by putting down their cigarettes, according to research out of the University of Groningen in the Netherlands.
The research is published in the December 15 issue of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

"We found that exposure to cigarette smoke appears to increase the thickness of the epithelium, or lining, of the airways in the lung. This may be the underlying cause of the fact that smoking asthma patients experience more asthma symptoms, such as shortness of breath and phlegm production, compared to non-smoking asthma patients," said Martine Broekema, Ph.D., the lead author of the study.

Dr. Broekema and colleagues examined patients with asthma who were assessed each for the severity of their asthma and allergy, given questionnaires to determine the extent of their smoke-induced symptoms, and then underwent bronchial biopsies. Of the total of 147 patients, 66 never smoked, 46 were ex-smokers and 35 were current smokers.In addition to the changes in the epithelial thickness, Dr. Broekema found distinct differences between the current smokers and the ex- and non-smokers.

"In addition to the epithelial thickening, we found that cigarette smoke negatively affects levels of exhaled nitric oxide, making it an unreliable indicator of asthma severity in smokers," she said.

Current smokers also had more mucous-producing goblet cells in their epithelium and, the epithelial cell layer contained more mucus protein overall, when compared to never-smoking asthmatics. "These pathological findings were associated with the severity of phlegm production reported by the asthma patients, suggesting a causal relationship between the two. Smoking asthmatics also showed a distinct inflammatory profile in their lungs compared to never-smoking asthmatics, with a lower number of eosinophils and higher number of mast cells," said Dr. Broekema. "Furthermore, our data suggest that smoking cessation can reverse the thickening of the lining of the airways.

"To determine the role of exposure length on asthmatic lungs, the scientists divided the ex-smokers into two groups: those with fewer than the median 3.4 pack-year exposure and those with more than 3.4 pack-years.Interestingly, while they expected to find evidence of a dose-response effect between smoking and epithelial remodeling, no such association was apparent between the number of pack-years or duration of smoking cessation and epithelial remodeling.

"To our surprise, these two sub-groups of ex-smokers showed no difference in any outcome measure. These sub-analyses indicate that the amount of smoke exposure in the past does not influence our outcome measures," said Dr. Broekema. "This study shows again how important smoking cessation is for pulmonary health, and this appears to be especially true for asthmatic patients. The good news is that quitting appears to have a measurable benefit in these individuals."

ACT bans smoking in outdoor eating areas

-ABC News

The ACT Legislative Assembly has passed tough laws banning smoking in outdoor dining and drinking areas.

Smoking is already banned in enclosed areas and the new laws will come into affect in 12 months.

Health Minister Katy Gallagher says it is a substantial step forward in reducing the harm caused by tobacco.
"In 12 months there will be no smoking in Canberra's restaurants, cafes and coffee shops," she said.

"Pubs and clubs however will be able to designate an outdoor smoking area of no more than 50 per cent of their outdoor space."

Ms Gallagher says food and drink will not be permitted in the designated smoking areas and people under the age of 18 will not be allowed in.

"This is protecting workers and members of the public from exposure to tobacco smoke," she said.

"Workers in the hospitality industry deserve the same protection that is provided to those working indoors."
The amended bill also bans smoking at all children's events.

"Not only will our children and young people no longer be exposed to the effects of tobacco smoke but the [ban] will also reinforce the no smoking message, helping to reduce the likelihood of young people taking up smoking," Ms Gallagher said.

The Opposition supported the legislation in general but health spokesman Jeremy Hanson raised some concerns.

"My concern is this will force smokers onto pavements rather than in designated smoking areas," he said.

"If that happens then that will be a negative consequence."
