E-cigarettes may also be used to deliver marijuana or other illicit drugs. E-cigarettes are often marketed as smoking cessation tools or as a safe alternative to tobacco. But these and other myths about e-cigs create a smokescreen of false security about the devices. Manufacturers have marketed e-cigarettes as a tool to help people stop smoking. But there is no conclusive scientific evidence that e-cigs are effective at helping people quit smoking long-term, according to the National Institute on Drug Abuse.
Food and Drug Administration has not approved e-cigarettes as a smoking cessation aid. The FDA has approved seven other quit-smoking aids that have been shown to be safe and effective. These include over-the-counter nicotine gum, lozenges and patches. It also includes two prescription drugs that do not contain nicotine, Chantix and Zyban. The National Academies of Science, Engineering and Medicine concluded in that there is limited evidence that e-cigarettes can be effectively used to stop smoking.
The academies also found insufficient evidence on whether e-cigarettes are an effective smoking cessation aid when compared to no treatment or to other FDA approved smoking cessation methods. Since e-cigarettes are a relatively new invention, little is known about their long-term health effects.
But a study presented at the Society for Research on Nicotine and Tobacco was the first to find evidence of long-term health risks of e-cigs. Researchers from the University of California San Francisco studied 70, people and found daily e-cigarette use doubled the risk of a heart attack. Scientists already know a lot about nicotine and other chemicals the devices deliver to users. Nicotine addiction can increase the risk of cardiovascular, respiratory and digestive tract diseases.
It also weakens the immune system, disturbs reproductive health and affects the health of cells in the human body, which can lead to cancer. Nicotine may also lead to Type 2 diabetes and insulin resistance. Other chemicals in e-cigarette liquids also pose serious health risks. There are more than 7, e-liquid flavors on the market in the United States. But the two most common chemicals are propylene glycol and vegetable glycerin. A study in PLOS Biology found that inhaling even small doses of these chemicals exposes users to high levels of toxins.
The researchers developed a system to quickly analyze the toxicity of different e-liquids. They found that flavors with more chemicals also posed greater risks to the user. The researchers also set up an online database of e-liquid chemicals.
E-cigarette users can search by flavor or individual chemical to find out how toxic their e-liquid is. Unlike tobacco cigarettes, e-cigs pose an explosion risk due to their lithium ion batteries. The batteries are generally safe and are used in a multitude of electronic devices, including cell phones and computers. But the batteries can catch fire or explode when they are damaged or defective.
While explosions are rare, the Federal Emergency Management Administration highlighted the unique risk of e-cigarettes in a report. Fire Administration documented fires and explosions associated with e-cigarettes between January and the end of These resulted in injuries, including 38 that the agency classified as severe.
The agency found that 62 percent of the reported fires or explosions involving an e-cigarette or its battery happened when the device was in a pocket or in use. In addition to potential long-term health effects of e-cigarettes, teens and young adults who take up vaping are at risk of quickly developing nicotine addiction, experiencing seizures and suffering upper respiratory problems. E-cigarettes have been the most commonly used tobacco product among young people since , according to an advisory from the United States Surgeon General.
And research by the National Academies of Science, Engineering and Medicine found evidence that vaping may lead teens to take up other tobacco products in the future. The Surgeon General estimated 1 in every 5 high school students and 1 in 20 middle school students used e-cigarettes in They also found moderate evidence that e-cig use put young people at a higher risk for coughing and wheezing as well as asthma-related incidents.
A study in the journal Pediatrics surveyed teens and young adults and found they are unaware that they inhale nicotine when using e-cigarettes. The researchers looked at adolescents who were between 12 years old and 21 years old. They found that 40 percent of the adolescents thought they had been using nicotine-free products but were actually inhaling the addictive chemical.
Young people may also be at risk for developing seizures linked to e-cigarette use. The FDA launched an investigation into the possible connection after it received 35 reports of e-cig users experiencing seizures since The agency said most cases involved teens and young adults. Nicotine in e-cigarettes can also affect brain development in teens. The human brain continues to develop into the mids. Brain cells build stronger connections, called synapses, each time a person learns a new skill or creates a new memory.
Young people build these connections faster than older people. But nicotine changes the way a brain forms synapses. Nicotine exposure during adolescence can affect memory, learning, mood, impulse control and attention. And it can increase addictive behavior, leading to abuse of other addictive substances. Altria is the parent company of Philip Morris, the maker of Marlboro cigarettes.
It controls more than half the tobacco cigarette market in the United States. As part of the deal, Altria promised to give up top-shelf display space in retail stores so that JUUL e-cigs could be displayed next to Marlboro cigarettes. Large tobacco companies have moved quickly into the e-cig business. Sales of e-cigarettes have been increasing even as sales of conventional cigarettes have plummeted. Some big tobacco companies prominently display their e-cigarette products on their websites and promote them to investors as products that will drive future profits.
