Yes, there are risks associated with vaping, regardless of what you vape. Using e-cigarettes for the first time, or transitioning from cigarettes to e-cigarettes, raises your chance of serious health consequences. According to the American Cancer SocietyTrusted Source, the safest approach is to avoid both vaping and smoking completely.

The study of the health implications of vaping is still ongoing, and we may not know the long-term risks for some time.

Here’s what we know about the impacts of vaping liquids with and without nicotine, as well as vaping marijuana or CBD oil right now.

What effect does vaping have on your heart?

According to preliminary study, vaping may be harmful to one’s heart.

E-liquid aerosols contain particles, oxidising agents, aldehydes, and nicotine, according to the authors of a 2019 review. These aerosols are most likely to harm the heart and circulatory system when inhaled.

The National Academies Press (NAP) published a paper in 2018 that revealed considerable evidence that taking a puff from a nicotine e-cigarette causes an increase in heart rate.

The scientists also mentioned that there is some evidence that puffing on an e-cigarette raises blood pressure. Both of these factors may have a long-term impact on heart health.

A 2019 study looked at data from almost 450,000 people in a nationwide survey and found no link between e-cigarette usage and heart disease.

They did discover, however, that persons who smoked both traditional and e-cigarettes were more likely to develop heart disease.

E-cigarette usage was linked to an increased risk of stroke, heart attack, angina, and heart disease in a 2019 study based on the same nationwide survey.

The authors of the 2018 study used data from a separate national health survey to reach the same conclusion: daily vaping is linked to a higher risk of heart attack, even when other lifestyle factors are taken into account.

Finally, a look back at 2017.

According to a reliable source on the cardiovascular consequences of vaping, e-cigarettes may offer some hazards to the heart and circulatory system, particularly for persons who already have heart disease.

Vaping, on the other hand, is regarded to be less damaging to the heart than smoking cigarettes, according to the study.

What effect does vaping have on your lungs?

Some data suggests that vaping is harmful to the lungs, but additional research is needed.

A 2015 study looked at the impact of flavoured e-juices on human lung cells as well as lung cells in mice.

Toxicity, oxidation, and inflammation were all noted as negative impacts on both types of cells by the researchers. However, these findings may not be applicable to vaping in real life.

In a 2018 study, ten adults who had never smoked cigarettes had their lung function tested immediately after vaping fluids with or without nicotine.

Vaping, both with and without nicotine, affects normal lung function in otherwise healthy adults, according to the researchers.

However, because this study had a small sample size, the findings may not be applicable to everyone.

According to the same NAP report from 2018, there is some indication that e-cigarette exposure has negative effects on the respiratory system, but further research is needed to determine the extent to which vaping leads to respiratory disorders.

Finally, the consequences on lung health are likely to take 20 to 30 years to manifest. This is why the bad health effects of cigarettes took so long to become generally acknowledged. It’s possible that we won’t know the full extent of the harmful impacts of e-cigarette materials for another three decades.


What effect does vaping have on your teeth and gums?

Vaping appears to have a lot of harmful dental health consequences.

According to a 2018 study, exposure to e-cigarette aerosol renders dental surfaces more susceptible to bacteria. The researchers came to the conclusion that vaping could raise the incidence of cavities.

Another study from 2016 found a link between vaping and gum inflammation, which is a known contributor in the development of periodontal disorders.

Vaping, according to a 2014 analysis, can cause discomfort in the gums, mouth, and throat.

Finally, the same NAP assessment from 2018 indicated that both nicotine and nicotine-free e-cigarettes can harm oral cells and tissues in non-smokers.

Is there anything more to think about in terms of physical effects?

NAP published a paper in 2018 that demonstrated strong evidence that vaping promotes cell malfunction, oxidative stress, and DNA damage.

While some of these cellular alterations have been connected to the long-term development of cancer, there is presently no evidence that vaping causes cancer.

Certain groups, notably young people, may have unique negative impacts from vaping.

According to a report from the Centers for Disease Control and Prevention (CDC)Trusted Source, vaping with nicotine can have a long-term impact on brain development in those under the age of 25.

It’s conceivable that we don’t yet understand all of vaping’s bodily impacts.


Is there a distinction between vaping and cigarette smoking?

Smoking cigarettes has long-term consequences, including an increased risk of stroke, heart disease, and lung cancer.

Cigarette smoking is responsible for approximately one out of every five deaths in the United States, according to the CDCTrusted Source.

For people who are trying to stop smoking, vaping may appear to be a safer option. Even if the vape liquid is nicotine-free, that doesn’t imply there aren’t risks involved.


Because we know that the lung consequences of vaping would take decades to develop, there is limited evidence of the long-term impacts of vaping to date. However, similar negative health outcomes, such as COPD, heart disease, and cancer, should be expected based on previous experience with cigarettes.

Secondhand vapour vs. secondhand smoke: what’s the difference?

Secondhand e-cigarette vapour exposure is claimed to be less harmful than secondhand cigarette smoke exposure. Secondhand vapour, on the other hand, is still a sort of air pollution that is likely to be harmful to one’s health.

Secondhand vapour contains nicotine, particulate matter, and volatile organic compounds (VOCs) in amounts that are higher than recommended, according to the 2018 NAP study.

More research is needed to determine the long-term health implications of secondhand e-cigarette vapour exposure.

Is there a distinction between vaping and using a Juul?

Vaping using a certain e-cigarette brand is known as Juuling. It has the same concerns as vaping in terms of health.

A Juul is a small, rectangular electronic cigarette that can be charged over a USB port.

The e-liquid is usually nicotine-based and comes in a Juulpod or J-pod cartridge.


Is it important that the liquid contains nicotine?

Vaping, whether with or without nicotine, is dangerous. However, vaping nicotine-containing goods raises the risk of addiction even more.

One of the most serious side effects of vaping with nicotine is nicotine addiction. According to a 2015 study, those who vape with nicotine are more likely to become addicted to nicotine than those who vape without it.

Vaping with nicotine is extremely dangerous for teenagers. Young people who use nicotine in their vapes are more likely to start smoking cigarettes later in life.

Even without nicotine, though, e-cigarettes offer health hazards.

A number of potentially harmful compounds, such as base liquids and flavouring ingredients, are found in nicotine-free e-juice.

Nicotine-free vaping has been shown in studies to irritate the respiratory system, cause cell death, produce inflammation, and injure blood vessels.

More research is needed to fully comprehend the negative impacts of nicotine-free vaping.

What about vaping CBD oil or marijuana?

If you vape marijuana, you may experience the following adverse effects:

coordination issues

In the long run, poor memory, difficulty answering problems, nausea and vomiting, and elevated heart rate dependent

There hasn’t been much research done on the negative consequences of vaping CBD. However, several CBD oil negative effects have been recorded, including:

fatigue \sirritability \snausea

These side effects are usually minor.


Other compounds, such as base liquids or flavouring ingredients, are commonly found in marijuana and CBD e-liquids. They may have comparable side effects to nicotine-free e-cigarettes.

Is the flavour of the fluid important?

The flavour of the fluid is important. According to a 2016 investigation, many vape fluids contain flavouring compounds in amounts that may be harmful to users.

Another study from 2016 looked at over 50 different e-juice flavours. The researchers discovered that 92 percent of the flavours tested positive for diacetyl, acetylpropionyl, or acetoin, three potentially hazardous compounds.

Cinnamaldehyde (found in cinnamon), o-vanillin (found in vanilla), and pentanedione (found in honey) were all found to be harmful to cells in a 2018 study.

Because ingredients vary from one brand to the next, it’s difficult to say which tastes contain respiratory irritants.

To be safe, stay away from the flavours listed below:

almond \sbread \sburnt \sberry \scamphor \scaramel \schocolate \scinnamon \sclove \scoffee

candies made of cotton

creamy \sfruity

herbal \sjam

nutty \spineapple \spowdery

thyme thyme thyme thyme thyme thy

tomato \stropical \svanilla


Are there any ingredients you should stay away from?

If you’re concerned about vaping’s harmful effects, stay away from the following ingredients:

acetoin acetyl propionyl acrolein acrylamide acetoin acetyl propionyl acrolein acrolein acrolein

acrylonitrile \sbenzaldehyde


citral \scrotonaldehyde

diacetyl \sethylvanillin

eucalyptol \sformaldehyde

pentanedione of o-vanillin (2,3-pentanedione)

oxide of propylene

pulegone \svanillin

The substances listed above are known irritants.

Are there any other options for reducing side effects?

If you’re worried about vaping’s negative consequences, try the following:

Inquire about the components.

Request a list of the chemicals in your vape juice from the manufacturer. If the producer is unable to offer a list of ingredients, this could indicate a potentially dangerous product.

Vape liquids with flavours should be avoided.

Flavoring compounds that are potentially hazardous are less likely to be found in unflavored vape liquids.

Reduce your nicotine intake.

If you’re using vaping to help you quit smoking, gradually reduce your nicotine intake. You can reduce adverse effects by switching to nicotine-free vaping.

Drink a lot of water.

To avoid symptoms like dry lips and thirst, drink water shortly after you vape.

After that, brush your teeth.

Brush to clean the surface of your teeth after vaping to reduce oral adverse effects.

When should you consult a physician?

It’s never a bad idea to consult a doctor or other healthcare provider about the dangers of vaping, especially if you have a chronic health condition like asthma.


If you think vaping is the cause of any new symptoms, such as coughing, difficulty breathing, or an elevated heart rate, you should see a doctor.
