Thirdhand Smoke Effects DNA

On March 17th, 2014 Fox News reported new findings on the effects of “thirdhand smoke” from cigarettes and how it can damage DNA.

The revealing information points to the significant consequences secondhand some has on personal and home furnishings when they become covered with second hand smoke.

Items like clothing, drapes and curtains, all types of furniture, carpets, wallpaper (really any item where second hand smoke adheres) become permanent toxic delivery vehicles.

Bo Hang, at the Lawrence Berkeley lab, found that when nicotine in secondhand smoke reacts with nitrous acid in the air, it creates new compounds called nitrosamines. Hang discovered that these nitrosamines can bond to human DNA in a way that damages genes and gives rise to the potential for cells to become cancerous.

Children are at greater risk of coming into contact with nitrosamines as they crawl about, drop things and pick them up, put their fingers in their mouths.

Thirdhand smoke is there all the time – means that your exposure doesn’t end when they put that cigarette out. You’re being exposed constantly,” Schick from the University of California commented.

Thirdhand Smoke Adheres to WallsThe entire news report reveals how the effects of smoking in a home can linger long after the smokers move from the residence. This revealing study makes one think twice before buying a car, RV, home or any used item that belonged to a smoker.

One study examined homes that were previously occupied by smokers and the effects on children who moved into them. They found the children actually had higher levels of nicotine in their blood than children who moved into non-smoking homes.

Firsthand, secondhand, and now thirdhand smoke reveals that effects linger and can harm anyone in contact.

Act Now on Cigarettes, Expert Says

An Australian adviser to the World Health Organisation has warned the ingredients of strawberry jam face tougher regulation than the deadly contents of cigarettes and has urged the Federal Government to act immediately.

A leading international expert on the health impacts of tobacco smoke, Dr Nigel Gray said he was disgusted that carcinogens in cigarettes remained unregulated, despite killing about 15,000 Australians each year.

“Controls apply to almost every marketed product from the amount of rat droppings permitted in wheat, to the amount of fat allowed in sausages and even the amount of mint allowed in nicotine replacement therapy,” Dr Gray said in an editorial published in the Medical Journal of Australia yesterday.

“It seems astonishing that the federal minister for drug and alcohol policy recently rejected claims that a new tobacco product (a ‘heatbar’, which heats but does not burn tobacco) should be subject to regulation and said there were no plans to even investigate the product.”

In June, The Age revealed that tobacco giant Philip Morris had secret plans to launch Australia’s first hand-held electronic smoking device. Dr Gray worked on a recent report by the WHO, which provided an international blueprint to regulate cigarette smoke and recommended the introduction of controls on two of the most dangerous carcinogens.

“The report found these compounds (nitrosamines) can be substantially removed from the cigarette because they occur during the process of curing tobacco,” Dr Gray said.

The US Government is considering the WHO recommendations and has a bill before Congress that would empower its Food and Drug Administration to regulate cigarette emissions.

But federal Minister for the Ageing Christopher Pyne said the Federal Government had banned all tobacco advertising and spent millions of dollars on education.

“For the Government to regulate the contents of cigarettes or to regulate products like the heatbar would undermine the message that all cigarettes are harmful and that quitting is the only option to avoid smoking-related illnesses. This is the approach we will continue to take,” Mr Pyne said.

Cancer Council spokeswoman Anita Tang said a failure to act was an implicit endorsement of cigarettes.

Philip Morris also supported the push for the contents of cigarettes to be regulated, despite opposition from other manufacturers.

Last night, Philip Morris spokeswoman Nerida White said: “We agree that the Australian Government should set in train a process of tobacco regulation, as is being discussed in the bill in the US Congress.”

Ms White said all cigarette manufacturers should be required to disclose the contents of their products.
