A typical battery-operated e-cigarette contains a cartridge of e-cig liquid, or juice, which will contains nicotine and the chemical propylene glycol. The juices are available in an array of flavors including cola and watermelon, which some say are meant to attract younger users. When used, the battery powers an atomizer that vaporizes the liquid in the cartridge for the consumer to inhale.
Aside from those basics, e-cigarettes บุหรี่ไฟฟ้า vary widely in terms of ingredients, construction and factors such as for instance battery voltage. The Food and Drug Administration, which regulates regular cigarettes, has proposed regulating e-cigarettes more tightly, but some politicians and many in the market oppose the FDA’s plan. Juice from e-cigarettes has different amounts of the addictive stimulant nicotine, from zero to about 72 milligrams per milliliter of liquid. (A traditional cigarette has 10 to 15 milligrams. ) “Nicotine has short-term negative health effects, like boosting your heart rate and blood pressure, therefore it can aggravate heart conditions, ” says Marvin M. Lipman, Consumer Reports’ chief medical adviser. “It also interferes with fetal development, which makes it unsafe in pregnancy no matter its source. ”
Larger doses of nicotine may be more harmful, especially to kids, who might be attracted by the sweet flavors and brightly colored packages. And in 2014, poison-control centers taken care of immediately 3, 783 e-cigarette and liquid nicotine exposure cases. More than half of the involved kids younger than 6 who might have ingested or inhaled liquid nicotine or gotten it on the skin or in their eyes. In 2015, those centers received 3, 067 nicotine-exposure reports across all age groups.
When propylene glycol is heated, it can degrade into formaldehyde, a chemical linked to nose and eye irritation, and an increased danger of asthma and cancer. The middle for Environmental Health recently tested 97 e-cig services and products and found formaldehyde and the chemical acetaldehyde in more than half of these. E-cig vapor can also contain lead, cadmium, nickel, tin and other metals, which could cause nervous-system or respiratory problems. Plus some flavoring chemicals, such as those used to produce cinnamon flavor, can be toxic.
But unlike conventional cigarettesบุหรี่ไฟฟ้า, e-cigs don’t burn tobacco. So they don’t produce the tar that clogs the lungs, or carbon monoxide, which can be linked to heart problems. Overall, experts say more research is required. But given what we all know now, vaping is less harmful than smoking tobacco. “If someone switches from smoking two packs per day to only using e-cigs, it’s never as good as quitting, but it’s undeniably better, ” says Douglas Kamerow, a former assistant surgeon general and a professor of family medicine at Georgetown University. “But if a non-smoker starts vaping and gets totally hooked on nicotine, particularly if it contributes to tobacco smoking, that’s a problem. ”
