Is secondhand vape smoke harmful？

Secondhand vape smoke is not just an annoyance; it can also be harmful. Inhaling secondhand vape smoke can contain high levels of nicotine, which can be addictive and dangerous. Not only that, but vaping has been linked to cancer in smokers and non-smokers. If you're concerned about the health risks of secondhand vape smoke, read on to learn more about what you need to know.

What are the effects of secondhand vape smoke?

Secondhand vape smoke is still smoke

The main concern with secondhand vape smoke is whether it harms people who aren't using e-cigarettes. Vaping devices produce aerosols containing nicotine and other chemicals that bystanders can inhale. Although there isn't much research on the effects of secondhand vapor, some studies have found that it can increase blood pressure and heart rate in people without heart disease, but not in people with heart disease. The long-term effects of secondhand vapor have not been studied yet.

A study published in 2017 found that levels of nicotine and formaldehyde — both known carcinogens — were higher in exhaled e-cigarette aerosol than in exhaled breath from conventional cigarettes or clean air after smoking conventional cigarettes or e-cigarettes. The researchers also found that levels of particulate matter were lower in exhaled e-cigarette aerosol than in exhaled breath after conventional cigarette use; however, those levels were still significantly higher than those found after breathing clean air before or after smoking conventional cigarettes or

Can secondhand vape smoke be harmful to your health?

Secondhand smoke isn't just harmful to the smoker; it can also be dangerous for those around them. A 2014 study found that secondhand smoke can cause asthma in children and increase the risk of lung cancer in non-smokers.

Secondhand vape smoke is often called "passive vaping" because it's not created by combusting anything. Still, it does contain some of the same chemicals found in regular cigarette smoke, including formaldehyde and ammonia. However, there has been little research into what effects secondhand vape smoke might have on health.

One study from 2016 found that secondhand vapor contains higher concentrations of diacetyl than regular tobacco smoke — but this doesn't mean that it's more harmful to your lungs or overall health because no one has ever studied the effects of long-term exposure to such levels of diacetyl.

What is the science behind secondhand vape smoke?

Many vapers are concerned about the potential for secondhand vape smoke to cause harm to bystanders. But what is the science behind secondhand vape smoke?

While the jury is still out on whether or not e-cigarettes are a healthier alternative to smoking, there is some evidence that vaping may be safer than traditional cigarettes. Researchers from California State University, Los Angeles, found that levels of harmful chemicals in e-cigarette vapor were far lower than in tobacco smoke.

According to Dr. Konstantinos Farsalinos, a cardiologist and medical researcher at the Onassis Cardiac Surgery Center in Athens, Greece, "E-cigarettes do not produce any toxicants at concentrations higher than those detected. In ambient air." Research has also shown that e-cigarette vapor produces significantly fewer toxins than cigarette smoke — so much so that it could be used as a nicotine replacement therapy product without causing harm to bystanders.

Should you avoid secondhand vape smoke?

There is a lot of debate surrounding the health effects of secondhand vape smoke. Some people believe it's just as harmful as smoking regular cigarettes, while others say it's not as bad as some people make it out to be. However, most experts agree that some risks are associated with secondhand vape smoke, including exposure to chemicals and toxins. If you're concerned about the health effects of secondhand vape smoke, weighing those risks against the benefits of using the devices is important.

Secondhand smoke may be harmful to your heart and lungs.

Secondhand smoke is a mixture of smoke from the burning end of cigarettes, cigars, and pipes, exhaled smoke, and the smoke breathed out by the smoker. It's also called environmental tobacco smoke (ETS).

Secondhand smoke contains more than 7,000 chemicals, including at least 69 that can cause cancer. The amount of these chemicals in secondhand smoke varies depending on how much tobacco is burned and what type it is. It also varies depending on whether the cigarette has a filter and how much ventilation there is where you're smoking.

Secondhand smoke can irritate your eyes, nose, throat, and lungs. This irritation may cause coughing, sneezing, runny nose, scratchy throat, shortness of breath, chest tightness, wheezing (whistling sound while breathing), bloody nose, or gum bleeding (caused by broken blood vessels), and sinusitis (inflammation in the sinuses). These symptoms can last for several hours after exposure to secondhand smoke.

If you have asthma or chronic obstructive pulmonary disease (COPD), exposure to secondhand smoke can worsen your symptoms by triggering asthma attacks or increasing coughing in people with COP.

Secondhand vape smoke might have less nicotine than secondhand cigarette smoke.

A new study from the University of Southern California found that secondhand vape smoke might have less nicotine than secondhand smoke.

The study compared nicotine levels in vapor from e-cigarettes and tobacco cigarettes, finding that the vapor contained only about one-tenth of the amount of nicotine in tobacco smoke.

Researchers also measured nicotine levels in exhaled air from e-cigarette users and compared them to non-users. They found that non-users had higher levels of nicotine in their exhaled air than those who used e-cigarettes daily.

"These findings suggest that e-cigarettes are a safer alternative to smoking," Dr. Norman Edelman, senior scientific advisor at the American Lung Association, told Reuters Health via email. "However, we still need additional data on exposure patterns over a longer period."

Conclusion

Secondhand vape smoke is a topic of much debate, with proponents and opponents claiming it is harmful. However, the scientific evidence for either side of the argument is inconclusive. So, while secondhand vape smoke may not be safe, it is still likely safer than smoking conventional cigarettes.
