Smoking

When you're trying to establish who was present when a crime was committed, every little clue helps. That's where a newly repurposed forensic technique comes in, as it can determine if oral fluid comes from a smoker or non-smoker.

After a decade of legal and political battles, the FDA finally issued a conclusive new ruling for warnings on cigarette packs. The 11 new labels will fill 50 percent of the package with text and graphic imagery depicting the consequences of smoking.

A study is offering the most comprehensive demonstration into how volatile organic compounds can spread throughout indoor environments from cigarette smokers’ clothing and bodies, however, the health risks from this kind of exposure are still unclear.

The FDA has finally approved two new low-nicotine cigarettes for the US market. The announcement comes less than a month after the FDA faced criticism for seemingly backing down on a 2017 initiative to regulate nicotine levels in cigarettes.

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.
