Carcinogens Form from Third-Hand Smoke

In tests at Berkeley Lab of celluose surfaces contaminated with nicotine residues from third-hand smoke, levels of newly formed TSNAs rose 10 times following a three hour exposure to nitrous acid. TSNAs are potent carcinogens.

Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens. This new potential health hazard was revealed in a multi-institutional study led by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab).

The vaccine is injected and works by creating anti-bodies

Smokers could soon have access to an injectable vaccine to help them break the habit following a deal between GlaxoSmithKline and Nabi Pharmaceuticals, the company that developed the drug.  The NicVAX vaccine works by preventing nicotine in tobacco entering the brain, where it creates an addictive sensation of pleasure.  Trials have shown it can halve the number of people who return to smoking after trying to give up.

The image shows sections though livers of mice. Mice exposed to second-hand smoke in the lab accumulated excess fat in their liver cells.

A team of scientists at the University of California, Riverside has found that even second-hand tobacco smoke exposure can result in nonalcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury in which fat accumulates in the liver of people who drink little or no alcohol.

New research shows that nicotine, the addictive component in cigarettes, “tricks” the brain into creating memory associations between environmental cues and smoking behavior.

Ever wonder why former smokers miss lighting up most when they are in a bar or after a meal with friends?
