Transcript for Millennial doctor uses TikTok to warn kids about the dangers of vaping
Thank you, Lara. To our "Gma" cover story. How the popular app tiktok is helping battle the teen vaping end kick. Janai Norman has the story of one doctor who warn teens about the dangers of vaping. Reporter: The American academy of pediatrics reporting more than 27% of high school students are using e-cigarettes. The organization calling on congress to pass the reversing the youth tobacco epidemic act which would prohibit flavored tobacco products including e-cigarettes, menthol cigarettes and flavored cigars but while the act is still in limbo in Washington, one doctor is turning to tiktok to address young people directly on the dangers of vaping. The video sharing app tiktok is known for its memes. But with youth vaping a national health emergency, it's more urgent than ever to reach kids. There's a new disease associated with vaping and you need to know about it. Reporter: Dr. Rose Leslie is going straight to her kids hanging out on tiktok. The family medicine resident at the university of Minnesota says it's a great way to reach out. It's been a great way for me to understand what health topics are important to youth and young Reporter: The 29-year-old doctor discussing the dangers on tiktok, even if it's not the most popular opinion. As long as the risks are out there, I still think it's a topic that I want to make sure I am talking about. Reporter: Followers like martin taking note. An avid smoker for five years finally calling it quits after he saw one of Dr. Leslie's videos. Here's a normal chest x-ray for reference. This is the chest x-ray of the person who has the new mysterious disease associated with vapeing. She showed the damage to your lungs and like I had never really had seen like x-ray photos of like damage to people's lungs after vaping so kind of like scared me and I wanted to do something about it. Reporter: As the CDC continues to investigate and hopefully learn more about the lung-related injuries tied to vaping, Dr. Leslie says getting information to teens is critical. I share health information the way that I would to one of my friends. I really think that that's the most effective way at talking about a health topic and getting people to listen. And janai Norman, thanks for that. Let's bring in Dr. Jen Ashton. I love the way this doctor is breaking through because it is so hard to reach teens where they live. Yep, and you know that as a parent, George, as do I. I think what's really important, you have to meet teenagers or any patient for that matter where they live. That means speaking their language. In this case leveraging social media. I think it's also really important to understand we have a lot of peer pressure factors to overcome, pop culture factors that may work for or against us depending on the issue and kids in particular, teenagers, they have difficulty placing their medical and health risks into perspective. Their frontal lobe isn't developed. They haven't lived as long as we have to understand exactly what's at stake. But you also have to be careful about going online for medical information. Yeah, whether you're a teenager or an adult. We talk about this all the time. I think it's very important to understand that should be the start of a dialogue about your health or medical condition. You have to understand where you're getting the information that person needs to be well credentialed. Not just with a screen in front of them and in some cases the messenger can be as important as the message so you have to take that very, very seriously but I like it as a point of departure to begin a discussion. We are doing this story just about every day because it is so important to get this message to teen. Yeah, you know what, it's a very complex issue. There's commercial and industrial and political aspects to it but medically I think we need an all hands on deck here while we're still accumulating information. We don't have all the answers yet and everyone needs to increase their awareness.
