Montreal smokers, non-smokers praise ban - The Montreal Gazette

Non-smoking week to raise awareness about deadly vice
Smokers and non-smokers seem to agree on at least one thing - they’re happy with the Quebec law banning smoking in bars and restaurants.
“I believe it should be banned everywhere,” said Nola Leblanc, in between puffs on her cigarette while standing on Ste. Catherine St. downtown Sunday afternoon.
“It’s my vice,” continued Leblanc. “I’m an addict to quitting. My mission is to quit before September because I’m going to become a grandmother.”
Daisy Alcinder, who was smoking alongside Leblanc on the chilly sidewalk, said she had read in the papers that this was a week dedicated to reducing smoking in Quebec. La Semaine québécoise pour un avenir sans tabac, which kicked off Sunday and continues until Saturday, is dedicated this year to raising awareness of the dangers of second-hand smoke.
“I thought it would be a good week to quit,” Alcinder said. “But it helps me think. It calms me down and puts my thoughts in place. But all in all, it’s a nasty habit, I know it.”
“We can’t smoke anywhere inside, which is fine for me because I’m a non-smoker,” said Pascale Younes. “When people smoke indoors, I get an irritation in my eyes.”
Fellow non-smoker Dany Acar is well aware of the health risks of smoking.
“People who smoke don’t breathe as well,” Acar said.
Montreal’s Mount Sinai Hospital will be holding the second annual Pink Lungs Day at Place Ville Marie on Tuesday, an event where people can talk to respiratory specialists and take a pulmonary function test. This will take place between 9 a.m. and 6 p.m. Tuesday in the food court.
On Monday morning, 16 Quebec teenagers with the mayors from each of their cities, will be holding a press event to ask people to not smoke in their cars if they are driving with children 16 years old or younger.
Quebec is the province in which parents smoke in front of their children more frequently than in any other province in Canada. Forty-three per cent of Quebec families have banned smoking in their households, compared with 64 per cent of families in the rest of the country, according to Health Canada. Each year, around 300 non-smoking Quebecers die from diseases caused by exposure to secondary smoke.

New research has revealed that prenatal exposure to nicotine increases the vulnerability to nicotine self-administration in adolescent mice
New research has revealed that prenatal exposure to nicotine increases the vulnerability to nicotine self-administration in adolescent mice. The results support the hypothesis that adolescents with prenatal nicotine exposure are more likely to start smoking earlier than their peers and that they are also more susceptible to the addictive effects of nicotine, especially as a result of stress and peer pressure. The study performed with mice is part of a project researching the behavioural and molecular mechanisms of nicotine addiction. The research project was carried out under the Academy of Finland's Research Programme on Substance Abuse and Addictions.
The key observation made by the Finnish and Russian researchers in the project was that adding nicotine to the drinking water of pregnant mice led to differences between the control and nicotine-exposed offspring in terms of nicotine self-administration. Treating the dams with nicotine during the prenatal period increased the frequency of self-administration in the offspring compared to the control group, even at lower doses.
The study also examined the receptor-level combined effects of opioids (morphine and morphine-related compounds) and nicotine. A receptor is a human protein to which endogenous and exogenous compounds bind. Once the receptors are activated, they trigger a number of intracellular signals. The compounds that bind to a receptor may also alter or turn off the receptor signalling. The present study was conducted using cell lines that express different subtypes of nicotinic receptors. Nicotine attaches to these receptors and activates them.
The results of the research project show that morphine and its related compounds, which normally attach to their own receptors, also bind to nicotinic receptors, causing altered nicotine responses. This provides a possible explanation for the common concurrent use of nicotine and other substances. The results may also pave the way for the development of new medication used to treat both smoking and drug addiction.
Groups want B.C. to pay for medication for smokers - CTV News
January 17, 2011
Two groups are calling on the B.C. government to pay for medication that will help people kick the habit.
The BC Lung Association and the Heart and Stroke Foundation of B.C. and Yukon say smoking must be treated as a serious chronic condition and that smokers should get subsidized access to quit-smoking medication and physician counselling.
The groups say Quebec and Saskatchewan already provide the subsidies.
Heart and Stroke Foundation CEO Diego Marchese says quit smoking medications are expensive and most public and private insurance plans don't cover them.
He says giving people access to the products is an important step to help them quit smoking instead of trying to do it cold turkey, which he says often fails.
The Lung Association and Heart and Stroke Foundation say research shows that 70 per cent of B.C.'s 550,000 smokers want to kick the habit.
