Juan Uranga smoked menthol cigarettes for 15 years. Five months ago, the Doral resident started vaping.
鈥淣ow that I switched to this, I just can鈥檛 stop smoking it, he said while shopping at the Vapor Shark smoke shop in South Florida, where he buys his 鈥榞o to鈥� e-juice 鈥� a tobacco-free liquid that serves as a replacement for nicotine. His favorite flavor: custard.
鈥淚t鈥檚 really helped with the cigarettes,鈥� he said. 鈥淚 don鈥檛 even smoke any more cigarettes.鈥�
Uranga is part of a surge in Floridians opting for flavored, tobacco-free liquid that鈥檚 inserted into something resembling a ball point pen. Batteries and a few clicks of a button, and heat coils turn the liquid into smoke.
Little more than a decade since they started being sold in the United States, 鈥榲aping鈥� has become a popular alternative to tobacco cigarettes 鈥� a known carcinogen.
But it鈥檚 also rising in popularity more quickly than existing health policy or the science on the long-term health effects of vaping. Right now, the Food and Drug Administration is reviewing whether or not to regulate e-cigarettes. And researchers from Miami and Tampa are launching new studies to better understand how e-cigarettes affect the body.
Sadallah Kahuk and his cousin own Euphoric Smoke shop in Hollywood, in a neighborhood with at least a dozen smoke shops. While their store specializes in hookah sales, a tribute to their roots in the Palestinian territories, sales shot through the roof once they introduced the flavored e-cigarettes.
鈥淚t鈥檚 popular because there are millions of flavors,鈥� he said. 鈥淵ou can go from a cereal to a desert to caramel to bacon.鈥�
Kahuk said smokers like that the ingredients for vaping feel less harsh than what is in traditional cigarettes, and that they can choose the level of nicotine in their solution and how much smoke the e-cigarette produces. He said he thinks it鈥檚 healthier than tobacco cigarettes.
鈥淚 mean it is better than cigarettes, just because of the different chemicals that go into cigarettes opposed to what鈥檚 in a vapor,鈥� he said. 鈥淵ou have glycerin, vegetable oil, flavoring and the nicotine.鈥�
But that feeling that electronic cigarettes are safer than tobacco isn鈥檛 a sure thing, said Dr. Mathias Salathe, a pharmacology professor at the University of Miami.
鈥淚t is completed unregulated at the present time, so (while) inhaling these vapors are considered safe by the general public ...in fact, our preliminary data suggests they are not.鈥�
The Florida Department of Health awarded Salathe鈥檚 research team a $2 million grant to follow e-cigarette users for 5 years. His earlier research, on animals, found that vaping causes many of the same problems as traditional cigarettes, like inflammation, which can lead to cancer.
Salate鈥檚 new electronic cigarette study will be one of the first to use human subjects. Over the next five years, the UM researchers will interview patients from local smoking cessation clinics, conduct routine checkups and monitor their health.
鈥淭he research here is really to find out whether there is a safety issue with e-cigarettes,鈥� he said. 鈥淥r should we just leave it alone because it is safe?鈥�
At the H. Lee Moffitt Cancer Center in Tampa, Dr. Thomas Brandon is trying to see if electronic cigarettes really are effective at helping people quit tobacco. He said unlike traditional nicotine replacements like gum or patches, smokers find e-cigarettes comforting.
鈥淭hey have the theoretical advantage of being more similar to cigarettes in how you use them. You know, the fact that they look like cigarettes, you bring them to your mouth like a cigarette, they produce something that looks like smoke. Smokers often find [it] calming just watching the smoke rise,鈥� said Brandon, whose work is being conducted as part of Moffitt鈥檚 .
Salathe, the UM Professor, said these studies could provide the U.S. Food and Drug Administration with data needed to better understand e-cigarettes.
鈥淭hey cannot regulate something without the science, so the science is interesting for public health policy,鈥� Salathe said.
The research also is coming at a time when the U.S. Centers for Disease Control and Prevention is reporting that the number of middle and high school students trying electronic cigarettes has tripled in the past two years.
Salathe said teens have always been drawn to cigarettes, but the perception that vaping is healthier makes it even more tempting
鈥淐igarettes [are] bad in the ad campaigns鈥ell, e-cigarettes are (advertised as) not being bad for you,鈥� he said. 鈥淎nd so you remove the danger and the cool factor comes in.鈥�
It doesn鈥檛 hurt that it鈥檚 less expensive than tobacco cigarettes. Uranga, the ex- tobacco smoker from Doral, said vaping has saved him money.
鈥淚 was wasting about $50, $60 a month, now, here, I鈥檓 wasting maybe $20, $30,鈥� he said of basic kits that cost about $20. The liquid vials cost as little as $5 each.
There鈥檚 the social factor, too.
Back in Hollywood, one block away from Kahuk鈥檚 Euphoric Smoke shop, Kosta Kokavessis and his friends are trying new e-cigarette flavors at a shop called Carbon Glass. Kokavessis, 20, never smoked tobacco, until he was hired at Carbon Glass.
鈥淚t鈥檚 just fun, like smoking and doing smoke tricks and stuff,鈥� he said.
Kokavessis and his friends said they can鈥檛 worry if vaping is dangerous to their health. Unlike decades of research 鈥� and millions of deaths - that proved cigarettes lead to cancer, the information about e-cigarettes just doesn鈥檛 exist.
Until there is, they say, they鈥檒l keep their fingers crossed that it鈥檚 going to be ok.
鈥淚t鈥檚 fun though,鈥� he said.
