Vaping, initially presented as a less harmful alternative to traditional smoking, delivers nicotine and is associated with perceived benefits such as improved attention, memory, and mood. Despite these initial positive perceptions and its lower harm profile compared to smoking, vaping has rapidly become a public health concern due to its unregulated nature, unknown long-term health impacts, and the alarming rate of addiction among adolescents.
Vaping is considered a less harmful alternative to smoking, delivering nicotine, one of the world's most popular drugs. Nicotine may improve attention, concentration, memory, reaction time, and endurance, while also reducing anxiety, stress, and enhancing mood. It can suppress hunger, aiding in weight management, and offers a pleasurable 'kick'.
Compared to other stimulants, nicotine's effects have a lower physiological cost. Vaping is significantly less harmful than smoking, as smoking delivers hot smoke and toxic particles directly into the lungs, causing immediate and serious body damage.
While smoking declines in Western countries, vaping has become a growing epidemic, particularly among teens. In 2023, 20% of UK children tried vaping, and 8% of US students regularly vape, with one in four doing so daily, predominantly using flavored vapes.
A vape consists of a small liquid tank heated by a metallic coil, which vaporizes the liquid. When inhaled, the heated coil turns the liquid into an aerosol mist, not actual vapor, a warm, sticky substance of large molecules and microscopic particles mixed with air, similar to inhaling warm body spray.
The major ingredients in most vape juice are propylene glycol and glycerol, commonly used chemicals in smoke machines and various industries, from food to cosmetics. These mixtures also contain nicotine salts and dozens of different flavor molecules. Upon inhalation, billions of aerosol particles cover the mouth and tongue, delivering pleasant tastes, and enter the lungs to reach alveoli, where nicotine passes into the bloodstream and travels to the brain to produce its effects.
The exact contents of vape liquids are often unknown, with studies finding thousands of different substance mixes, many not listed on labels. The vaping industry faces significantly less regulation than expected. While many official vape substances are technically safe for eating or skin application, their safety when inhaled is not established.
Specific chemicals like cinnamaldehyde (from cinnamon oil) kill cells and cause genetic damage when inhaled, while benzaldehyde (from almonds or apples), common in fruit-flavored vapes, irritates the respiratory tract as a gas. Heating vape juice can alter chemicals, creating new compounds with unknown consequences, especially when propylene glycol and glycerol decompose into harmful molecules if overheated.
When the metal coil heats up, it releases various metal particles, including aluminum, boron, calcium, iron, copper, magnesium, zinc, lead, chromium, nickel, and manganese. These particles range from harmful to toxic, potentially causing lung irritation, chronic bronchitis, and shortness of breath, with nickel also being a carcinogen when inhaled. The interactions among these substances are also unknown.
The full extent of vaping's harm is unknown due to its relatively recent emergence (approximately ten years). Most human health studies have focused on smokers who switched to vapes, making it difficult to assess effects on non-smokers. While switching from smoking to vaping drastically reduces disease risks, the long-term effects on individuals who never smoked are yet to be determined, with the first large-scale study on non-smokers beginning only in 2024.
In the short term, a significant number of vapers experience poor breathing symptoms, including coughing, excess mucus, shortness of breath, wheezing, and throat and chest pain. Vaping activates the immune system, causing inflammation, fluid seepage into the lungs, and increased mucus production, potentially leading to cell death. Vaping may also stress the body by increasing heart rate and blood pressure, lowering blood oxygen, stiffening blood vessels, and causing oxidative stress that could lead to various diseases over time. The long-term impact on the risk of strokes, heart diseases, lung diseases, or cancer remains unknown.
Vaping delivers extremely high nicotine doses, making it intensely addictive. Unlike smoking, which is harsh, vaping is less aggressive and odorless, allowing for constant, prolonged use and easy consumption of an entire vape in a day. This supercharged nicotine delivery contributes to its addictive nature.
High nicotine doses are particularly detrimental for teenagers, whose brains are still developing and whose nicotine receptors are especially active. These receptors are linked to the reward system, and nicotine may alter brain development by overstimulating them, potentially leading to cognitive deficits, hyperactivity, reduced impulse control, attention issues, and mood disorders. Whether nicotine directly causes these issues or if individuals with emotional dysregulation are more prone to using it remains a 'chicken and egg' problem.
The theory of nicotine as a 'gateway drug' has largely been rejected; instead, individuals predisposed to risk-taking are more likely to engage in various risky behaviors, including addiction to smoking, alcohol, cannabis, hard drugs, or gambling. This does not diminish vaping's addictiveness but suggests it may not cause other addictions.
Quitting nicotine is challenging due to severe physical and psychological withdrawal symptoms. These include intense cravings, irritability, mood swings, anxiety, difficulty sleeping, fatigue, headaches, concentration issues, reduced joy, increased stress, and weight gain from a returning appetite. The physical symptoms are reversible, with nicotine leaving the body in about 72 hours and the worst symptoms fading within a few weeks.
Vaping's appeal lies in its pleasant taste and stimulating effects, but it exacerbates nicotine's addictiveness. While a smoker switching to vaping benefits global health, vaping has regrettably hooked a significant portion of younger generations on nicotine. Scaring people away from vaping is ineffective, as it often causes more stress, leading users to cope by vaping more. Vaping essentially makes a declining addictive substance appealing to millions of teens through flavors, presenting a new global addiction that needs to be curbed before it becomes uncontrollable.
