Are they safer than tobacco? Or are they an advanced way to hook a new generation on a bad nicotine habit?
They look like the real thing. The end glows as you inhale. As you exhale, you puff out a cloud of what looks like smoke.
All e-cigarettes work basically the same way. Inside, there's a battery, a heating element, and a cartridge that holds nicotine and other liquids and flavorings. Features and costs vary. Some are disposable. Others have a rechargeable battery and refillable cartridges.
The nicotine inside the cartridges is addictive. When you stop using it, you can get withdrawal symptoms including feeling irritable, depressed, restless and anxious.
E-cigarettes are smoke-free and tobacco-free, but they're not nicotine-free. The liquid in e-cigarettes is typically a combination of nicotine, flavorings, propylene glycol and other additives.
Cigarette smoke contains more than 7,000 chemicals, and among those, 69 are known carcinogens. But it's not only regular cigarettes that are toxic to our bodies; e-cigarettes, too, come with health and safety concerns. The problem is the liquid nicotine.
Liquid nicotine is extracted from tobacco, but unlike tobacco leaves, liquid nicotine can be lethal. It can cause harm when it's inhaled, but it can also be harmful when ingested or absorbed through your skin.
Some testing suggests it's not only the nicotine that may be dangerous. Certain e-cigarette devices may also release metals during use. Cigarette smokers are known to be at higher risk for developing cancers, the biggest risk being lung cancer. Despite the marketing claims that e-cigarettes are safer than smoking tobacco, researchers are finding e-cigarette users experience diminished lung function, airway resistance and cellular changes, regardless of whether or not they currently, or ever, smoke cigarettes.
The e-cigarette comes in many shapes and sizes. Many look more or less like long cigarettes; others look like cigars or pipes. They all work the same basic way:
The user inhales through a mouthpiece. Air flow triggers a sensor that switches on a small, battery-powered heater. The heater vaporizes liquid nicotine in a small cartridge The heater also vaporizes propylene glycol in the cartridge. This is the stuff of which theatrical smoke is made. The user gets a puff of hot gas that feels a lot like tobacco smoke. When the user exhales, there's a cloud of propylene glycol vapor that looks like smoke. The vapor quickly dissipates. E-cigarettes contain no tobacco products; even the nicotine is synthetic.
So what's an e-cigarette good for?
For smokers who don't plan to quit tobacco, some firms point to e-cigarettes as a way to smoke in smoke-free environments such as airplane lounges, restaurants, and workplaces.
For smokers who don't want to give up their nicotine addiction, some suggest that switching to e-cigarettes will reduce the harm of their habit.
For smokers who want to quit, some suggest that e-cigarettes may help people transition from smokers to nonsmokers
In our product you have nicotine or no nicotine, propylene glycol, and some flavoring. In cigarettes you have nicotine, propylene glycol, and 4,000 chemicals and 43 carcinogens.
You can decide for yourself if e-cigarettes are for you or not. Point is that smoking is bad for you and quitting that habit will be better for your overall health.
