Cigarette consumption around the world
According to the World Health Organization (WHO), nearly 6 million people are killed as a consequence of tobacco, either directly, by smoking it or just by being exposed to second hand smoke. By 2030, almost 8 million people, mainly from low and middle-income countries, would have died as a consequence of cigarette smoking. The tobacco addiction is now considered as one of the most important epidemics that our society faces and several strategies have been developed by governments to lower smoking rates among the population.
Cigarettes, nicotine and disease
All tobacco products contain nicotine, which is a stimulant drug that causes addiction and makes it very hard for smokers to quit this habit.
In order to help smokers in the process of quitting this habit, several approaches have been developed to reduce tobacco consumption, such as taxes on tobacco products and bans on tobacco advertisements. A different alternative is the substitution of tobacco with other products that contain nicotine.
The e – cigarette: How does it work?
Electronic cigarettes were invented in China and have been in the U.S. market since 2007. Despite this, e-cigarettes are not regulated by the Food and Drug Administration (FDA). According to this organism, there is a pending modification on the current rule that regulates tobacco products in order to include e-cigarettes, but this is still in revision.
In other words, they are battery-operated devices that are designed to deliver nicotine, flavor and other chemicals in the form of aerosol. The aerosols that e-cigarettes produce are inhaled by the user, just as if it was a regular cigarette. Where does the nicotine and chemicals come from?
The e-solution is constituted by nicotine, propylene glycol and glycerol, that work as solvents and humidifiers respectively, flavoring agents and other chemical compounds that are known to be toxic, such as aldehydes, phenols and metals.
