Tobacco use is a major risk factor for multiple cancers, heart disease, stroke and lung disease. Approximatelykids now under 18 and alive in Texas who will ultimately die prematurely from smoking Approximately 28, adults die of a smoking-attributable illness annually in Texas. That is more than die from AIDS, heroin, cocaine, alcohol, car accidents, fire and murder - combined.
Farsalinos corresponding author and Riccardo Polosa. Electronic cigarettes are a recent development in tobacco harm reduction. They are marketed as less harmful alternatives to smoking.
Awareness and use of these devices has grown exponentially in recent years, with millions of people currently using them. This systematic review appraises existing laboratory and clinical research on the potential risks from electronic cigarette use, compared with the well-established devastating effects of smoking tobacco cigarettes.
Currently available evidence indicates that electronic cigarettes are by far a less harmful alternative to smoking and significant health benefits are expected in smokers who switch from tobacco to electronic cigarettes. Research will help make electronic cigarettes more effective as smoking substitutes and will better define and further reduce residual risks from use to as low as possible, by establishing appropriate quality control and standards.
Complete tobacco cessation is the best outcome for smokers. However, the powerful addictive properties of nicotine and the ritualistic behavior of smoking create a huge hurdle, even for those with a strong desire to quit.
Until recently, smokers were left with just two alternatives: This gloomy scenario has allowed the smoking pandemic to escalate, with nearly 6 million deaths annually and a predicted death toll of 1 billion within the 21st century [World Health Organization, ].
But a third choice, involving the use of alternative and much safer sources of nicotine with the goal to reduce smoking-related diseases is now available: They are electrically-driven devices consisting of the battery part usually a lithium batteryand an atomizer where liquid is stored and is aerosolized by applying energy and generating heat to a resistance encircling a wick.
The liquid used mainly consists of propylene glycol, glycerol, distilled water, flavorings that may or may not be approved for food use and nicotine. Since their invention inthere has been constant innovation and development of more efficient and appealing products. Currently, there are mainly three types of devices available [Dawkins, ], depicted in Figure 1.
Batteries may be disposable to be used once only or rechargeable. In the most recent atomizers you can simply change the atomizer head resistance and wick while keeping the body of the atomizer, thus reducing the operating costs.
These devices can be combined with either second-generation atomizers or with rebuildable atomizers, where the consumers have the ability to prepare their own setup of resistance and wick.
The importance of using nicotine in the long-term was recognized several years ago by Russell, indicating that the potential of nicotine delivery systems as long-term alternatives to tobacco should be explored in order to make the elimination of tobacco a realistic future target [Russell, ].
However, current regulations restrict the long-term use of pharmaceutical or recreational nicotine products such as snus [Le Houezec et al.
Surveys have shown that electronic cigarettes are used as long-term substitutes to smoking [Dawkins et al. Nicotine overdose or intoxication is unlikely to occur with vaping, since the amount consumed [Farsalinos et al.
Moreover, although not yet proven, it is expected that vapers will self-titrate their nicotine intake in a similar way to tobacco cigarettes [Benowitz et al. Last, but not least, there is evidence suggesting that nicotine cannot be delivered as fast and effectively from electronic cigarettes compared to tobacco cigarettes [Farsalinos et al.
Therefore, it seems that electronic cigarettes have a huge theoretical advantage in terms of health risks compared with conventional cigarettes due to the absence of toxic chemicals that are generated in vast quantities by combustion.
Furthermore, nicotine delivery by electronic cigarettes is unlikely to represent a significant safety issue, particularly when considering they are intended to replace tobacco cigarettes, the most efficient nicotine delivery product.
Laugesen performed the first studies evaluating the chemical composition of EC aerosols [Laugesen,].
Toxic chemicals such as heavy metals, carcinogenic polycyclic aromatic hydrocarbons and phenols were not detected, with the exception of trivial amounts of mercury 0. Laugesen evaluated emissions based on a toxicant emissions score and reported a score of 0 in electronic cigarettes compared with a score of — for tobacco cigarettes Figure 3.
They detected the presence of tobacco-specific nitrosamines TSNAs but did not declare the levels found. Small amounts of diethylene glycol were also found in one sample, which was unlikely to cause any harm from normal use.
Another study identified small amounts of amino-tandalafil and rimonambant in e-liquids [Hadwiger et al. Subsequently, several laboratories performed similar tests, mostly on liquids, with Cahn and Siegel publishing a review on the chemical analyses of electronic cigarettes and comparing the findings with tobacco cigarettes and other tobacco products [Cahn and Siegel, ].
The authors concluded that, based on chemical analysis, Electronic cigarettes are far less harmful compared with tobacco cigarettes. The most comprehensive study on TSNAs has been performed recently by a South Korean group, evaluating liquids obtained from local retailers [Kim and Shin, ].
On average, they found The estimated daily exposure to nitrosamines from tobacco cigarettes average consumption of 15 cigarettes per day is estimated to be up to times higher compared with EC use Table 3. Etter and colleagues evaluated the accuracy of nicotine labeling and the presence of nicotine impurities and degradation products in 20 EC liquid samples [Etter et al.
Although in some samples the levels were higher than those specified in European Pharmacopoeia, they are not expected to cause any measurable harm to users.Despite enormous progress in reducing smoking, tobacco use is still the leading cause of preventable death in the United States and imposes a terrible toll on families, businesses and government.
Tobacco kills more than , people annually – more than AIDS, alcohol, car accidents, illegal drugs, murders and suicides combined. Health Risks of Smoking Tobacco. smokers who don’t inhale are breathing in large amounts of smoke that comes from their mouths and the lit end of the cigarette, cigar, or pipe.
They are at risk for lung cancer and other diseases caused by secondhand smoke. E-cigarettes have also been claimed to promote smoking cessation. However, the extent of residual risk associated heavy toll of misery, disease, and death9,10 that cigarettes have effects of conventional cigarettes They fear that acceptance of e-cigarettes might renormalize smoking, promote dual use.
death in the United like regular cigarettes.
They can look like bright metallic pens. Vape pens can also explode and cause severe skin burns. 5. E-cigarette use can be linked to alcohol use and Call the Suicide Prevention Hotline toll-free number at Even though tobacco companies almost never marketed light and mild cigarettes with explicit claims of reduced health risks, promotions focused on reduced exposure (lower tar and nicotine) made smokers believe they were reducing their health risks by switching to light cigarettes–17 Later, tobacco companies went further to promote light and.
Smoking cigarettes is the number one cause of chronic obstructive pulmonary disease. chronic obstructive pulmonary disease is the fourth leading cause of death globally.
