Alarming new research reveals that nicotine use among high school students was at a 20-year-high in 2019, just two years after hitting an all-time low.
Researchers published their findings in The Journal of the American Medical Association after examining the smoking habits of between 15,000 and 36,000 students in grades 6 through 12 from 1999 to 2020.

Those numbers have decreased every year since, and in 2020 only 1.6% of middle school students and 4.6% of high school students were smoking cigarettes.
In fact, the use of all tobacco products had been on a steady decline until 2017, when things suddenly shifted and numbers began to rise again.
Since 2014, e-cigarettes have been the most commonly-used nicotine or tobacco product among middle school and high school students.
Usage steadily rose until 2018, when the number of students vaping jumped from 11.7% to 20.8% among high school students and from 3.3% to 4.9% among middle school students.
That was just a preview of what was to come as those numbers soared higher the following year, with 27.5% of high school students and 10.5% of middle school students vaping in 2019.
The Risks of Vaping
Dr. Sheela Ahmed, a pulmonologist at Fox Chase Cancer Center, says that e-cigarettes are in many ways much worse than actual cigarettes.
“E-cigarettes don't burn tobacco, so they are marketed as containing fewer toxic chemicals than regular cigarettes,” says Dr. Ahmed. “However, this is not true. In the short term, vaping has caused acute lung injury and respiratory failure, which is something not attributed to regular cigarette use.”
As for the chemicals in those e-cigarettes? A “cocktail of nicotine, toxic metals, propylene glycol and glycerol, flavorings, and other chemicals that can reach deep into the lungs,” according to Dr. Ahmed.
There is also much concern around a 2019 study published in Proceedings of the National Academy of Sciences of the United States of America that examined the effect of vaping on mice. That study revealed that vaping caused cells to change in just a matter of months.
That would suggest DNA is being injured and the body is failing to repair those injured strands, which is how cancer begins to form in the human body.
"As a cancer center, we are very concerned about the animal studies showing that e-cigarette smoke caused cancer in mice and, in the future, we want to study DNA changes in the cells of people who vape," explains Dr. Ahmed.
Until that time though, she suggested that the “establishment of community education programs regarding the risks of vaping” would be helpful.
A study published earlier this year Lung Cancer detailed the oncogenic effects of e-cigarettes.
Oncogenes are genes that have the potential to cause cancer.
The piece cited nicotine derivatives and heavy metals as just two of the problematic ingredients in e-cigarettes which could be cause for concern.
That study closed with a warning.
“Although research remains somewhat equivocal, there is clear reason for concern regarding the potential oncogenicity of E-Cigarettes/E-Liquids with a strong basic and molecular science basis,” read the study.
“Given lag times (extrapolating from tobacco smoke data) of perhaps 20 years, this may have significant future public health implications. Thus, the authors feel further study in this field is strongly warranted and consideration should be made for tighter control and regulation of these products.”
What Has Been Confirmed About Vaping-Related Illness?
According to the Centers for Disease Control and Prevention (CDC), there have been 68 vaping-related deaths in the U.S. as of February 2020 and another 2,807 people have been hospitalized due to vape-related illnesses.
The CDC said that data show that an additive called vitamin E acetate, which is included in some vaping and e-cigarette products that contain THC (the psychoactive compound in marijuana), is strongly linked to the outbreak of vaping-related illnesses. However, the organization also notes that there could be other chemicals contributing to the outbreak.
“The big problem with vaping and JUUL is that we just really don’t know what’s going to happen with it,” Dr. Brendon Stiles, chief of thoracic surgery & surgical oncology at Montefiore and Albert Einstein College of Medicine, told SurvivorNet when discussing the issue in a previous interview.
Dr. Brendon Stiles discusses the possibility that vaping can lead to serious lung illnesses
Dr. Stiles noted it’s very important to research vaping because, like smoking cigarettes, there’s a chance that this will be a lifestyle factor that leads to lung disease down the line. Considering the number of teens who currently admit to vaping (more than 25% of high school students), there’s a chance that a health crisis is coming in the next decade or so.
“Are there compounds in vaping that we’re just not regulating and we don’t know anything about that may cause secondary insults or inflammation in the lungs? There’s plenty of history of other inflammatory lung conditions causing or triggering lung cancer,” Dr. Stiles said. “So, to me, it’s not a great leap to think that inhalation from vaping could trigger lung cancer down the road or other inflammatory lung diseases.”
