E-Cigarettes: A Safer Source of Nicotine?
Anyone who has tried to quit smoking knows it can entail herculean efforts. Withdrawal symptoms from nicotine and constant cravings for a cigarette cause many smokers to quit on quitting. Some smokers may be tempted to try electronic cigarettes - or e-cigarettes. They may sound like a healthier option. But these devices may be no safer than traditional cigarettes.
Like the common cigarette, e-cigarettes jolt the body with nicotine. But you don't burn them. Instead, these battery-operated devices heat up and convert nicotine into a vapor. The nicotine comes packaged in replaceable cartridges. These cartridges may also contain other chemicals, including flavorings like chocolate, mint, or coffee. In a process called "vaping," users insert a cartridge in the e-cigarette and then inhale the emitted vapor.
E-cigarettes are often designed to mimic other nicotine-providing products, such as cigarettes, cigars, or pipes. They can also look like everyday objects, such as pens or USB devices. Some versions have a built-in light on the tip that glows when puffed. They may also contain a chemical called propylene glycol that, when vaped, simulates smoke.
Manufacturers of e-cigarettes have claimed their products are healthier than regular cigarettes. They have also recommended e-cigarettes as a quit-smoking aide. The problem? These claims lack supporting scientific data. E-cigarettes may emit no smell and leave no ash, but not enough research has been done yet to say they are safer or effective in helping smokers quit.
A study in the journal Chest provides some compelling evidence against the use of e-cigarettes. Researchers measured how e-cigarettes affected the lungs of a small group of smokers. After only 5 minutes of using an e-cigarette, study participants showed signs of inflammation in their lungs. The study results suggest using e-cigarettes for a long period of time may harm the lungs and body.
Until more is known, the National Lung Association and the FDA recommend that consumers not use e-cigarettes. Their main concerns: Some chemicals in cartridges may be toxic. The amount of nicotine in cartridges may also vary from what is advertised on the label; some tests have found cartridges to contain more or less of the addictive substance.
