Earlier this summer, my 17-year-old patient Tryston just wasn’t feeling like himself.

“I was tired all the time. My energy was low. I was losing some weight.”

Then, things quickly turned downhill. He started having chills. He was feeling really exhausted all the time, was nauseous, and had some fevers.

When he started becoming short of breath and having some chest pain, he and his mother decided it was time to head to an urgent care clinic, where he was given antibiotics and flu medications.

In 24 hours, he felt worse. His breathing became more difficult. Something was definitely wrong.

He came to Cook Children’s, and the doctors and nurses quickly realized what poor shape he was in. X-rays showed something that looked like pneumonia on both sides of his chest. But the specialists were confused, because it just wasn’t obvious.

Within 48 hours however, what WAS obvious was that Tryston was getting worse.

As his Cook Children’s pediatrician, I was sent daily updates about him. I found myself holding my breath every time I opened the update – and audibly gasped the moment I realized that he was intubated.

This means a tube was stuck down into his windpipe to breathe for him.

And the tube stayed there for the next 10 days. Machines were keeping Tryston alive. He was in the ICU, where the sickest children in the hospital stay.

“I lost a lot of sleep over this kid,” said Mary Suzanne Whitworth, M.D., medical director of Infectious Diseases at Cook Children’s. Dr. Whitworth wasn’t sure what was going on, and became very close with the family.

Was it an infection? No organism seemed to grow from cultures. Was it an autoimmune disease? The rheumatologists didn’t think so.

Even a lung biopsy – a piece of his lung which was cut out and examined under a microscope – didn’t seem to hold any clear and obvious clue as to why he was so sick. His lungs just failed, and he was in something called respiratory distress.

He was put on numerous antibiotics and antifungal medications to see if they’d help. He was needing more and more oxygen. He even needed special high-frequency ventilations (think little tiny rapid puffs of air) to keep his lungs open and working.

There’s one thing I haven’t mentioned yet. The one thing that was in the back of everyone’s minds.

One thing that Tryston mentioned to the staff of Cook Children’s before he got very ill is something I already knew, and had talked to him about the year prior.

Tryston liked to vape.

Most of you have heard about “vaping” in some way or another, but if you haven’t watched the news lately (or been in my office lately - because jeez, I am hearing more and more about it daily), “vaping” is when someone smokes an aerosolized chemical, usually from something called an e-cigarette.

Vaping is becoming VERY popular amongst teenagers. Statistics show 45% of U.S. teens have tried it. The Centers for Disease Control and Prevention is now investigating the "sudden emergence of severe lung disease linked to vaping in 14 states. Ninety-four possible cases of severe lung illness associated with vaping have been reported from the end of June to Aug. 15, the CDC reports.

Corwin Warmink, M.D., the medical director of Emergency Services at Cook Children’s, says he has seen multiple patients come through the ER and his team sees a child every week for vaping. But it’s not just teens, we are also seeing younger children, 5 and under, who have ingested vaping liquid. Scary stuff.

The most popular types look like USB devices. They’re super easy to hide. They have different “fun flavors” like mango, crème brulee and fruit medley. Some of the devices are even cute, with teddy bears on them.

They are more addictive than cigarettes. One Juul pod (currently the most popular brand) has the same amount of nicotine as an entire pack of cigarettes! “And I know lots of kids smoking 2 or 3 pods a week,” Tryston told me.

And though they claim to be a “healthier option” to regular cigarettes, I beg to differ. Inhaling chemicals is inhaling chemicals. There are over 40 different chemicals in vaping liquids. And they can cause some major damage.

They can hurt delicate lung tissue. We are seeing more and more reports of teenagers and young adults suffering severe lung injuries and seizures coming out in the news lately.

I’m really worried about how addictive these things are. Kids who want to quit are finding it more difficult to do so than if they’d smoked a pack a day.

Want to know why you should quit?

Tryston spent 18 days at Cook Children’s.

He lost almost 30 pounds. He is re-learning how to walk normally again. He has no muscle mass in his legs anymore from being bedridden for almost three weeks. He is still coughing at times. He feels very tired.

A clear answer for why his lungs failed him was never found.

“We don't know for sure. But there are literature reports of hypersensitivity pneumonitis from vaping. I told him no inhaling anything again, ever. We still don't know for sure what the trigger was. But it is very plausible that it could be due to his vaping,” Dr. Whitworth said.

The general consensus was that his lungs were severely injured, and I believe his vaping habits had a lot to do with it.

Two days after going home, he walked into my office for a follow-up visit. We had a very real, very brutal heart-to-heart.

I said, “Tryston, buddy…you know you could have died, right?” and he looked me in the eye and said “I’ll never touch the stuff again, Dr. Diane. And I want everyone to know that. I want to tell my story. And if I can just keep one kid from going through what I did, it’ll all be worth it.”

So here I am, telling you his story. Tryston is a great kid with a great heart. He made a mistake, one that LOTS of kids are making, because they assume e-cigarettes are “healthier” than regular cigarettes.

And Tryston wants us all to learn from it. Do me a favor and do what he has asked: print this out, and give it to your teenage son or daughter. Ask them to read it.

Let them know it’s just not worth it.

• Tobacco Use Increases By More Than 38 Percent Among High School Students

That's the question CNN recently asked, based on a question from a substance abuse counselor. 

Research from Truth Initiative shows that 25 percent of 15- to 24-year-old JUUL users refer to their behavior as “JUULING.”

The Juul e-cigarettes closely resemble flash drives. So much so that some schools have banned flash drives from their campuses. The vapor cloud from the Juul is "so small and dissapates so quickly that teachers are usually none the wiser," 16-year-old student told CNN.

Scott Gottlieb, the Food and Drug Administrator Commissioner, called teenage vaping an "epidemic" and announced his group would work to stop retailers from selling e-cigarettes to minors and warned of a possible ban on flavored e-cigarette liquids.

The scary part is that kids may not even be aware of what they are inhaling when they JUUL.

The nicotine cartridge inserted into the Juul gives about 200 puffs, about as much nicotine as a pack of cigarettes, according to the product's website. In five weeks, that's about 100 cigarettes.

In a survey of 1,018 15- to 24-year olds, the Truth Initiative found that 37 percent of teens were uncertain if they were inhaling nicotine, even though it states on the JUUL website that each pods is equal to 200 cigarette puffs, the equivalent of a pack a day.

The Boston Globe calls Juuling “the most widespread phenomenon you’ve never heard of.”

While you may not know about this form of vaping, there’s a good bet your kids have.

“Juuling in the bathroom” has become so widespread among young people, some school administrators are warning parents about the dangers of e-cigarettes, including the brand called Juul.

BuzzFeedNews describes the Juul as a “portable nicotine-delivery device” designed to mimic the physical and sensory experience of a cigarette, without looking like one.

Men’s Fitness magazine described the Juul as the “iPhone of E-Cigs.” The author of the story said he asked a dozen people to guess what the Juul was, and all of them guessed a USB stick.

The fact that it delivers nicotine designed to mimic the experience of a cigarette, but doesn’t look like one, makes the Juul popular among teens.

BuzzFeed estimates over 50,000 posts under the hashtag #Juul on Instagram alone.

Juul is still too new to have any data specific to its risk as a product, but recent research has shown the dangers of teens vaping. But researchers from the University of California, San Francisco challenge the idea that e-cigarette vapor is safe. They found that teens who use e-cigarettes are in danger of inhaling cancer-causing chemicals, especially in fruit flavors.

“The presence of harmful ingredients in e-cigarette vapor has been established; we can now say that these chemicals are found in the body of human adolescents who use these products,” authors wrote.

The UC San Francisco researchers found that adolescents who smoke e-cigarettes expose themselves to a high levels of the potentially cancer-causing chemicals also found in tobacco cigarettes, even when the e-cigarettes do not contain nicotine.

"Teenagers need to be warned that the vapor produced by e-cigarettes is not harmless water vapor, but actually contains some of the same toxic chemicals found in smoke from traditional cigarettes," said lead author Mark L. Rubinstein, MD, a professor of pediatrics at UCSF. "Teenagers should be inhaling air, not products with toxins in them."

This was the first known study to report on the potentially cancer-causing compounds in the bodies of adolescents use e-cigarettes, according to UCSF. The lists of compounds include acrylonitrile, acrolein, propylene oxide, acrylamide and crotonaldehyde.

Another study from the same institution and also published in Pediatrics found that “e-cigarette use is more likely to encourage youth smoking than to divert youth from smoking.”

The team found those who had ever used e-cigarettes were significantly more likely than never users to have smoked at least 100 cigarettes at follow-up, have smoked during the past 30 days or both.

To learn more about e-cigarettes, we talked to Don Wilson, M.D., an endocrinologist and an Endowed Chair of Cardiovascular Health and Risk Prevention at Cook Children’s.

What do e-cigarettes do?

E-cigarettes are designed to simulate the act of smoking and deliver nicotine without the toxic chemicals produced by burning tobacco. The use of nicotine, however, is highly addictive. Recent research suggested nicotine exposure may also cause the brain to become addicted to other substances. Vapor from some e-cigarettes has also been shown to contain known cancer producing and toxic chemicals, such as diethylene glycol and nitrosamines, as well as small particles of toxic metals. Although not well studied, there is the potential for second hand exposure by others in the environment.

How do e-cigarettes work?

E-cigarettes are smokeless, battery operated devices designed to deliver nicotine mixed with a variety of flavorings (fruit, mint, chocolate, etc.) and other chemicals via an inhaled aerosol. They typically resemble regular tobacco cigarettes, cigars, pipes or everyday items like pins or USB memory sticks.

Most e-cigarettes generally contain three components: a cartridge that contains a liquid solution containing various amounts of nicotine, flavoring and other chemicals, a heating device or vaporizer, and a rechargeable battery. Puffing on the e-cigarette activates the battery powered heating device causing the liquid to vaporize. The vapor is inhaled by the user. E-cigarette vapor may include metals, rubber and ceramics which may be aerosolized and have adverse health effects.

Are e-cigarettes safe?

Although a limited number of studies have been conducted, the safety of e-cigarettes has not thoroughly been evaluated in scientific studies.

Here are a few points to consider:

• Nicotine is highly addictive and has negative effects on brain development from infancy to teens.
• Potential consequences of using e-cigarettes among youth include nicotine addiction, withdrawal and the potential for overdose.
• The use of a variety of flavoring in the liquid solution of e-cigarettes has created concern for accidental ingestion by smaller children.
• With the rapid increase in use of electronic nicotine delivery systems (ENDS), users and nonusers are exposed to the aerosol product. While e-cigarette aerosol may contain fewer toxins than cigarette smoke, studies evaluating whether e-cigarettes are less harmful than cigarettes are inconclusive.

Bottom line: e-cigarettes are often promoted as safer alternatives to cigarette smoking. Although very little is known about their safety, they are increasingly being used by youth and young adults.

What about second hand exposure?

The potential exists for secondhand nicotine and other tobacco-related toxin exposures to others. Studies have shown that e-cigarettes are a source of secondhand exposure to nicotine but not to combustion toxins. Thus, while use of e-cigarettes in indoor environments may involuntarily expose nonsmokers to nicotine, it does not seem to expose them to toxic, tobacco-specific combustion products.

What does the American Academy of Pediatrics recommend?

To protect the health of youth, the American Academy of Pediatrics has made the following recommendations:

• Sales of e-cigarettes to minors (under 18 years of age) should be prohibited.
• Candy and fruit flavored e-cigarettes, which encouraged youth smoking initiation, should be banded.
• To avoid exposing others to potential harm, laws should mandate smoke-free environments which include e-cigarette vapor.
• To prevent poisoning, all e-liquids should be required to be sold in child-proof packaging.
