E-cigarettes are still fairly new, and scientists are still learning about their long-term health effects. Here is what we know now. Most e-cigarettes contain nicotine, which has known health effects. Besides nicotine, e-cigarette aerosol can contain substances that harm the body. Most e-cigarettes contain nicotine, which is addictive and toxic to developing fetuses.
Nicotine exposure can also harm adolescent and young adult brain development, which continues into the early to mids. And youth e-cigarette use is associated with the use of other tobacco products, including cigarettes. For more information about the risks of e-cigarettes for young people, visit Quick Facts on the Risks of E-cigarettes for Kids, Teens, and Young Adults. E-cigarette aerosol generally contains fewer toxic chemicals than the deadly mix of 7, chemicals in smoke from regular cigarettes.
It can contain harmful and potentially harmful substances, including nicotine, heavy metals like lead, volatile organic compounds, and cancer-causing agents.
E-cigarettes are not currently approved by the FDA as a quit smoking aid. The U. Preventive Services Task Force, a group of health experts that makes recommendations about preventive health care, has concluded external icon that evidence is insufficient to recommend e-cigarettes for smoking cessation in adults, including pregnant adults. However, e-cigarettes may help non-pregnant adults who smoke if used as a complete substitute for all cigarettes and other smoked tobacco products.

Not many people realize that e-cigarettes, like JUUL , also contain nicotine. Nicotine levels in e-cigarettes can vary greatly from one brand to the next. Your brain is a hive of activity with billions of neurons processing, storing, and sending information all the time. The way that messages get from one neuron to another is through special chemical messengers the neurons produce, called neurotransmitters.
Nicotine is shaped similarly to a neurotransmitter called acetylcholine. It can mimic it when you absorb nicotine into your body. This can cause signaling activity in your brain to increase when you smoke, making you feel more energized. Over time, the neurons in your brain start to compensate for this increased activity by making fewer acetylcholine receptors. Nicotine also has the ability to mimic dopamine. Basically, to sum it all up, nicotine alters the chemical functions in your brain.
This is what concerns public health organizations and the medical community alike. Beyond being a potentially addictive substance and changing your brain chemistry, nicotine can affect your health in many different ways. Some other health effects of nicotine include:.
The high variability in performance properties of ECs was recently reported by Trtchounian, Williams, and Talbot They found that EC brands produced aerosols, which varied in density from puff to puff. Our findings seem to confirm their hypothesis about not uniform nicotine delivery from ECs. Nicotine levels from a single puff of 70 ml may be estimated to be between 1. Results of repeated testing of ECs with three different cartridges with the same label menthol high by the FDA gave varying results from Despite the fact that we tested products with lower puff volumes than in the FDA study 70 vs.
Assuming a series of 15 puffs is equivalent to smoking one cigarette; this allows us to make some dose comparisons. One series of 15 puffs might have delivered 0. By systematically analyzing how much of the nicotine was released from an EC with every 15 puffs, we were able to generate a nicotine delivery profile for each tested product.
Thus, making conclusions on how much nicotine is inhaled by EC users based on the content in cartridges might lead to overestimation of the effective dose.
Improvement of the vaporization efficacy would make more or even all the nicotine present in a cartridge available for EC users. Moreover, nicotine delivery profiles provided interesting data on efficacy of the vaporization process, indicating that most of the nicotine is delivered during the first — puffs. Based on this finding, potential users of the products should be instructed to replace nicotine cartridge every puffs in order to achieve effective and steady nicotine exposure.
Our results also suggest that some products are inconsistent in delivering nicotine. These products might deliver different levels of nicotine to their users each time they are used even if containing cartridges of the same nicotine content.
This finding is consistent with the results found in a study by Williams and Talbot The authors reported that the ECs they tested lasted for a variable number of puffs, and some variation was found in models within a brand, when different cartridges were used. We also found significant differences between labeled and true levels of nicotine in cartridges and refill solutions.
Traces of nicotine were also detected in one of two cartridges labeled as containing no nicotine. These findings indicate that information about nicotine levels provided on product packages may be misleading to customers.
In order to sell the best quality products to customers, manufacturers of ECs should develop and implement quality standards for their products and follow good manufacture policy.
The authority to independent agencies should be given to control quality of the products available on market. We presented a preliminary evaluation of 16 ECs, 20 cartridges, and 15 refill solutions and our study was not intended to provide an accurate characterization of any particular brand. There are many potential limitations in the generality and reliability of our findings because of a relatively small number of samples from each product. Further research is needed to investigate if the variability in nicotine delivery is primarily due to brand variability or a combination of brand variability and fluctuation within brands.
Our study reflects the early stage of objective research on ECs and raises new questions. First, how high might nicotine levels be if users were instructed to puff them as hard as possible? Puff duration for individuals using ECs in YouTube videos was longer than we used in the study to simulate EC use with smoking machine 4.
Longer puff duration may help EC users compensate for the poor delivery of nicotine from ECs. Second, what is the prime site of nicotine absorption from EC? Does nicotine from EC reach blood stream via buccal mucosa only? Finally, can ECs produce the arterial plasma spikes reflecting substantial lung delivery as have been shown with tobacco cigarettes? The study sponsor had no involvement in the study design, collection, analysis, and interpretation of data, the writing of the manuscript or the decision to submit the manuscript for publication.

Nicotine Levels in Electronic Cigarettes. Oxford Academic. Tomasz Kuma, M. Michal Gawron, M. First, many teens believe that vaping is less harmful than smoking.
Second, e-cigarettes have a lower per-use cost than traditional cigarettes. Finally, vape cartridges are often formulated with flavorings such as apple pie and watermelon that appeal to younger users.
Both youths and adults find the lack of smoke appealing. With no smell, e-cigarettes reduce the stigma of smoking. And, it often leads to using traditional tobacco products down the road.
But the sooner you quit, the quicker your body can rebound and repair itself. Talk to your doctor about what smoking cessation program or tools would be best for you. One of the best things you can do to protect and improve your health is to stay informed. Health Home Wellness and Prevention. The CDC recommends that people: Do not use THC-containing e-cigarette, or vaping, products Avoid using informal sources, such as friends, family or online dealers to obtain a vaping device.
