CNN went to New York's Washington Square Park to speak with young people who had or are currently experiencing a steamy habit of understanding their experiences, thoughts and reactions to recent health warnings.
Here are their stories.  "I was constantly in the process of juicing a storm."
Sydney Kinsey, a 21-year-old New York University student, began smoking cigarettes abroad in London. Their habit intensified during a semester abroad in Buenos Aires, Argentina. To quench her nicotine addiction she got a Juul in June. A Juul is an e-cigarette device, slightly smaller than a pen that uses nicotine-filled pads in liquid form.
She initially liked it to be practical and did not smell like cigarette smoke. Recently, however, she feels worse at her use.
"I found I was feeling worse physically and head-on-I got a lot more scared, but then my joints and lungs hurt more," she said. "I have used it more often than ever before (cigarettes)." Instead of going out and smoking like a cigarette by day, I was like the uninterrupted juicing of a storm that is not fun. "
So she quit about a week ago and dumped her Juul in a trash can in the city so she did not change her memory. She said she misses it.
"It's like my phone, it's just as addictive as my phone, as if I just had it in my pocket and I miss it in my pocket to do something with it." she said.
"You Can Feel It Hurts Your Lungs"
That's no surprise to Laura Kesnig, 21.
She When she was in New York New School, she began trading black market THC cartridges, and she knew they were not good for her.
"They buy them illegally, so who knows what's going on in them," she said. "It's funny, because when you hit it, you can feel it hurt your lungs, it does not feel like hitting a joint or anything, it hurts you."
"But we're just so It's okay, it's grass, it can not hurt you. And then this stuff comes out and it's like we knew it all the time.
Kesnig said she started smoking marijuana at the age of 15, but because of his ease, she turned to vaporizing THC.
"They were just that easy. she said, "you do not have to do anything. You just buy it and then you just hit it and it's that easy.
The ease of steaming compared to lighting a joint made her more addictive and she felt her concentration wane when she used it. She used up her last THC cartridge last week and returned to "good, old, normal grass".
"(I feel) actually better, frankly better," she said.
"I know it's bad"
Brooklyn Johnson's entire family smokes cigarettes but tobacco never appealed to her.
Instead, the 20-year-old NYU student bought a juul this summer on a whim and is now vaporizing about a pod per week.
"I just had the idea f for two years in the back of my mind, and then this is um, as I was, whatever man, I'll just do it, "she said. "It was not really a big deal, I think, I just thought, I know it's bad, I probably should not, and then I just gave in." just something to do.
"(It is) to have something in my hands and to do it, there is a head-thrust, but it's more of an activity than a way of feeling it," she said. "If I watch TV, I'll be a juvenile."
After reading the news about the steam-related lung diseases, she said she thought she should probably stop.
t. I do not know, "she said," That sounds morbid, but I think there are more likely ways for me to die than Juuling. "
" I've agreed to it "
Juul Labs says his product "was always thought of as an alternative to the one billion adult smoker in the world."
Nevertheless, Ethan Uno tried the first time a friend Juul was at a party when he was 17 years old he was old and after a short while he became addicted to one night.
"At the end of the night I loved the way the nicotine felt," he said. "I got one the next day and I'm pretty much into it eingegan
Uno, a 20-year-old from San Diego, California, knew it was not good for him. But it was so accessible.
"You can do it literally at any time of the day, like doing your homework, so it was so easy," he said.
He vaped consistently for about six months, but then only sporadically. He had not touched nicotine for more than a year, he said, a decision he had made partly out of concern that it would damage his health.
And that made me unconscious of it, "he said.
The medical cases of steam-related lung disease were personal to him, saying that a friend's baby brother had been hospitalized with a lung disease, most likely due to vaping
"Eating like a biscuit"
With a Purple NYU Lanyard Around her neck – the telltale mark of a college freshman in her first weeks of schooling – Olive ran into a Juul
"I just like it," the 18-year-old said of steaming, "It's the same kind of where you like to eat a cookie. I just enjoy it. "
She said she picked up the habit of friends from Washington state and has been vaping for a few months now, but she has read the health news and said she plans to" soon It's a loose plan, she admitted.
"It just makes me crazy that we do not know the long-term effects of fumes, as we do with cigarettes, but I do not know. It's just a bit scary, "she said.
Olive declined to give her last name, saying that her mother, an ambulance, would not be happy with her, which was another reason they quit
"So I really feel guilty. I feel bad, "she said," If my mother knew, she would be angry. "
" It seems she's scared. "
Stephen Cambor, 20, began steaming for the first time when he was about 14 years old, in eighth or ninth grade, and he well remembered his first time because it "put me on my ass," he said.
"I thought," Oh, I can stand up for 10 seconds and then go back to class, "he said. "Like a really strong head buzzing to the point where all the blood feels like a buzz."
