Smoking

A new study has found e-cigarettes can damage human blood vessel cells and potentially increase the risk for cardiovascular disease. The study revealed some e-cigarette flavoring liquids are more damaging than others, regardless of nicotine concentrations.

Following complete bans on e-cigarettes in countries like Brazil and Singapore, San Francisco recently proposed new legislation to essentially follow suit. What is underpinning these calls to ban vaping? Is it really a gateway for young people into using tobacco products?

An international team of researchers has harnessed two known metabolic modulators, tobacco smoking and exposure to cold, to create a potential anti-obesity treatment that in early mouse experiments has successfully lowered body weight and corrected glucose intolerance.

New research has revealed a promising new candidate to help smokers kick their damaging addiction. An enzyme has been engineered that can gobble up nicotine in the bloodstream before it reaches the brain, with the compound proving to be incredibly successful in early animal tests.

Weight gain has often been noted as a side effect of quitting smoking, and research has found that nicotine can function as an appetite suppressant. A study has now uncovered a novel mechanism showing how nicotine directly activates a protein that signals a type of fat cell to start burning energy.

A new study has found that third-hand smoke – chemical residue from cigarette smoke – can spread more pervasively than previously thought, even moving throughout a seemingly “smoke-free” building. But despite this compelling research the dangers to human health still remain unclear.

​If you've recently stopped smoking, then you ought to start eating more tomatoes and other fruits. According to a new study from Johns Hopkins University, doing so could help slow the decline of your lung function, by reversing some of the damage caused by smoking.

While e-cigarette vapor certainly doesn't contain the same kinds of carcinogenic compounds as regular cigarette smoke there is a growing body of research to suggest “vaping” may have its own set of unique harmful effects.

The 6 trillion cigarettes produced every year generate over 1.2 million tonnes of toxic butt litter in the environment. Now, researchers at RMIT University in Australia have found a new way to safely dispose of cigarette butts: seal them up inside roads and paths.

​A new study has found the vapor from electronic cigarettes, or e-cigarettes, can cause as much DNA damage as smoke from tobacco cigarettes. The results surprised researchers, who concluded that e-cigarettes are "potentially as harmful as tobacco cigarettes."

For years researchers have noted an unusual association between smoking and schizophrenia. New research may have finally solved the mystery while also paving the way for the development of new, more targeted treatments for several mental health conditions.

Organs-on-chips allow the study of drugs and diseases without testing on animals or humans. Now a team at Harvard has designed a device that smokes cigarettes and sends the smoke through a lung-on-a-chip, to examine just how the habit damages health.
