E-cigarette is an electronic apparatus, designed in the form of a cigarette, motorized by lithium battery set. The nicotine is vaporized in the form of aerosol for a person to inhale, rather than the process of combustion which is applicable in normal cigarettes. The smoking instrument is weightier than the traditional cigarette and puffing procedure necessitates some preparation and time. The basic principle followed by this technology is the “smokeless cigarette implementation” facilitating prevention of the Carbon-mono oxide dependent cardiovascular and lungs problems.
Components of E-cigarette
The basic components of an e-cigarette are a mouthpiece through which a person inhales the aerosol (aping the feeling of smoke inhalation), a solid container or cartridge (carrying the main liquid inhaling solution), a heating element or an atomizer (for dissociation of the liquid solution at a temperature of around 100 degree Celsius or more), a rechargeable battery to run the system. Ultimately, this inhaled aerosol or commonly termed as vapor is puffed out.is the indispensable component of any electronic Cigarette. It acts as the systematic liquid fuel in the functioning of this vaping technology.
The liquid comprises of around 95% propylene glycol with water or sometimes with vegetable glycerin as the base carrier element, to which about 5% of flavoring agent (tobacco or fruit) and nicotine is added. There are more than 5000 reported flavors used in the liquid. Propylene Glycol (PG) has no taste or smell (odor), thus it does not interfere with flavor. PG might give a dry-mouth side-effect to the inhaler. Vegetable glycerin (VG), however is more consistent (thicker), having a hint of sweetened smell. VG also enhances the aerosol forming capacity of any e-cigarette due to its viscosity. There are also preferences of having no nicotine at all in the e-liquid. The nicotine concentration also varies with demand.
Pros and Cons
The range of nicotine as advised is 0-20 mg/ml. This vapor stays in the surrounding air for a very short period of time (with the half-life of about only 10 seconds) as compared to the smoke emitted by regular cigarettes which remains in the air for quite a long period of time. The lowered levels of nicotine are meant to help, release the ardent smokers from the addiction (scientifically coined as nicotine dependence which shows numerous ill affects by hyper-activating sympathetic nervous system), so that the dose can go down to zero steadily. High level safety measures are taken into consideration while manufacturing the components of e-liquid.
The disposal of batteries and cartridges after use, needs better monitoring. These Cigarettes have shown to effect bystanders (lesser than traditional smokers), especially indoors. So it is recommended to avoid smoking inside a closed arena where the dense ultra-particles settle more, due to low temperatures, so that particularly children can be excluded from the bystander effect. The nanoparticle components of the e-liquid tends to move deep into the lung alveoli and coagulate around, also augments nicotine absorption. A consolidated long term study is required to know more about the merits and demerits of e-cigarettes. It is rightly said “Prevention is better than cure” and the users should ponder on these lines before taking any step forward that can equally benefit or harm them.
