Have you ever wondered why the allure of vaping has grown exponentially among young people? With one out of every five high school students in the US and 7% of UK kids aged 11 to 17 now vaping, it's a trend that's hard to ignore. But what if we told you that this seemingly harmless activity could be more dangerous than smoking cigarettes? Let's delve into the science behind the vapor.
From the moment you inhale, the nicotine in vapes hits your bloodstream and brain faster than cigarettes. Vapes contain a coil that heats up to temperatures ranging from 110°C to 1,000°C. This heat transforms the carrier, like propylene glycol, into a stage smoke-like substance. Mixed with nicotine and chemical flavorings, this vapor races into your lungs, delivering a potent dose of nicotine more quickly than traditional cigarettes.
But why does this matter? Each puff from a vape delivers more nicotine than a cigarette, making it an incredibly potent drug. The nicotine rush is intense, and the cravings set in within just four hours of your last hit. This cycle of addiction is more pronounced with vapes due to their higher nicotine content.
The effects of nicotine extend beyond addiction. It alters blood flow, leading to potential erectile dysfunction, with one study finding men who use e-cigarettes are more than twice as likely to experience this issue. But it's not just about the nicotine; the chemicals in the flavorings are equally concerning.
Take cinnamon flavoring, for instance. The chemical cinnamaldehyde, used to create that taste, has been found to impair the function of cilium in your lungs. This makes it harder for your lungs to clear debris and pathogens, leaving you more susceptible to lung infections. And it's not just cinnamon; chemicals like 2,5-dimethyl pyrine and isothiazolinone acetate, used for chocolate and banana flavors, have been linked to pro-inflammatory effects and cancer.
Remember the vaping deaths that made headlines? By February 2020, 287 patients were hospitalized with severe lung issues, and 68 died, some of whom were under 18. These deaths were linked to THC vapes, which are less regulated than nicotine vapes. The presence of vitamin E acetate in some THC vapes led to a disease called e-cigarette or vaping use-associated lung injury (EVALI), causing symptoms like coughing, wheezing, and chest pain.
While scientists and physicians agree that cigarettes are still worse due to the tar and chemicals from combustion, the dangers of vaping cannot be overlooked. Vaping is a relatively new concept, and much is still unknown about its long-term effects, especially on young people's lungs.
So, what's the bottom line? Vaping may not yet be considered worse than smoking, but it's a new frontier with its own set of risks. As we continue to explore these implications, it's crucial to stay informed. For more information about vaping, you can listen to our podcast here. Stay tuned.
