We sell e‑cigarettes — and that's exactly why we think it's important to be honest about what's currently known regarding their health effects. "Vapes are safe" is a marketing line, not a medical one. Reality is more nuanced: vaping is less harmful than smoking cigarettes, but not harmless. Let's go through the details.
What a vape is, technically
An electronic cigarette is a device that heats a liquid — usually containing nicotine — until it forms an aerosol you inhale. The liquid typically has four components: propylene glycol, vegetable glycerin, flavorings and, most often, nicotine salt. Disposables like Mickey 50,000 work the same way: pre‑filled liquid, built‑in battery, coil.
Key point: the aerosol is not "water vapor", as old marketing brochures insisted. It's a fine suspension of nicotine, volatile organic compounds, metals from the heating element and the breakdown products of flavorings. All of that ends up in the lungs.[1]
Nicotine: the main active ingredient
Nicotine in a vape is the same molecule as in a cigarette. The difference is dosage and delivery. A single Mickey 50,000 disposable (5% nicotine, ~13 ml liquid) contains roughly 650 mg of nicotine — the equivalent of about 5–7 packs of cigarettes. Because it uses nicotine salt, absorption can be even faster than with tobacco cigarettes.[2]
- Addiction forms in most regular vapers within a few weeks. Same mechanism as smoking: dopamine reinforcement, tolerance, withdrawal.
- Cardiovascular effects: nicotine raises heart rate and blood pressure, constricts blood vessels. With regular exposure it's a risk factor for hypertension and coronary heart disease.
- Adolescent brain: the brain is still developing until about 25, and nicotine affects the structures responsible for attention, learning and impulse control. That's why all major regulators (WHO, FDA, national health services) prohibit selling vapes to minors.[3]
What's known about lung effects
EVALI — the 2019 outbreak
The loudest vaping‑related health incident was the EVALI outbreak (E‑cigarette or Vaping Use‑Associated Lung Injury) in the U.S. in 2019–2020. CDC recorded more than 2,800 hospitalizations and 68 deaths.[2] The primary culprit was later identified as vitamin E acetate in black‑market THC cartridges, not vaping as such — but EVALI was the trigger for a wave of tighter global regulation.
Long‑term effects
Honest answer: we don't have complete data on what happens to someone who vapes for 20 years — e‑cigarettes have only been mainstream since 2007. But short‑ and mid‑term studies show:
- Irritation and inflammation of the airway lining.
- Reduced mucociliary clearance (the lungs' ability to clear dust and microbes).
- In adolescent vapers, higher rates of bronchitis episodes and shortness of breath compared to non‑vaping peers.[1]
- Metals (lead, nickel, chromium) have been detected in the aerosol of some devices — a long‑term risk factor for lungs and other organs.
Vaping vs cigarettes: which is less harmful?
Two very different questions here.
For a non‑smoker, vaping is unambiguously worse than not vaping. Starting to vape when you don't smoke is a bad move — you're picking up nicotine addiction from zero.
For a cigarette smoker, switching to vaping reduces exposure to most known combustion carcinogens. Public Health England, in its 2015 review, put vaping at "around 95% less harmful than smoking".[4] That figure isn't a hard scientific value — it's an expert estimate and is regularly criticized. More conservative estimates put it at a 5–10x reduction, not safety.
WHO in its 2024 report is explicit: vapes should not be treated as a "safe substitute" for cigarettes — they're nicotine products with their own risks, and their use should be either a doctor‑supervised cessation tool or not at all.[1]
Who should absolutely not vape
- Minors. Developing brain + nicotine = lasting change to the reward system.
- Pregnant and breastfeeding people. Nicotine crosses the placenta and into breast milk, affecting the fetus and infant.
- People with cardiovascular disease (coronary disease, arrhythmia, hypertension) — nicotine makes it worse.
- People with asthma or COPD — aerosol triggers bronchospasm.
- People allergic to liquid components (propylene glycol, flavorings).
If you vape anyway — how to reduce risk
This isn't a "safe vaping guide" (there's no such thing) — it's about minimising what's already happening:
- Don't buy from grey channels. Underground liquids and cartridges are exactly what caused EVALI. Only reputable brands.
- Don't chain‑vape. Non‑stop puffs every few seconds overheat the coil and boost emission of aldehydes and metals.
- Don't dry‑hit. If you taste "burnt" — the device is empty or faulty, stop.
- Watch total nicotine intake. Many vapers end up consuming more nicotine than they smoked. You'll notice through withdrawal symptoms.
- Regular check‑ups — GP, pulmonologist, cardiologist. Especially if you have symptoms: shortness of breath, cough, chest pain.
How to quit
Good news: quitting vaping is on average a bit easier than quitting cigarettes — you've already dropped combustion products and some of the ritual. Bad news — nicotine addiction is the same, and that's the part you have to detach from.
- Stepwise reduction of nicotine strength (5% → 3% → 1.5% → 0%) over 1–3 months.
- Nicotine replacement therapy (patches, gum) — under medical guidance.
- Tracker apps and peer support groups — simple but effective for many.
- In severe cases — prescription drugs (varenicline, cytisine) via a doctor.
