Introduction: Why Understanding the Body’s Response to E‑Cigarettes Matters
Electronic cigarettes, commonly known as vapes, have rapidly moved from a niche hobby to a mainstream phenomenon. In Australia, brands such as IGET and ALIBARBAR have become synonymous with high‑quality disposable devices, offering flavors ranging from “Grape Ice” to “Mango Banana Ice.” While the sleek design and convenience of these products attract millions, the physiological interaction between vapor and the human body remains complex.
This article dissects the science behind e‑cigarette use, exploring how nicotine, flavorings, and aerosol particles influence each organ system. By grounding the discussion in peer‑reviewed research, toxicology data, and clinical observations, the goal is to equip readers with a clear, evidence‑based picture of both short‑term effects and potential long‑term consequences.
1. Anatomy of an E‑Cigarette – From Coil to Cloud
1.1 Core Components
| Component | Function | Typical Materials |
|---|---|---|
| Battery | Supplies power (3–5 V) to heat the coil. | Lithium‑ion cells, regulated circuits. |
| Atomizer/Coil | Converts electrical energy into heat, vaporizing the e‑liquid. | Kanthal, Nichrome, Stainless steel; sometimes ceramic. |
| Tank/Cartridge | Holds e‑liquid; provides airflow. | Glass, food‑grade plastic, stainless steel. |
| Mouthpiece | Directs aerosol to the user’s mouth/lungs. | Polypropylene, silicone. |
| E‑liquid | Solution of nicotine, propylene glycol (PG), vegetable glycerin (VG), and flavorings. | Pharmaceutical‑grade PG/VG, nicotine salts or freebase nicotine, GRAS‑listed flavor additives. |
1.2 How the Device Generates an Aerosol
When the user activates the device, the battery powers the coil. The coil temperature typically ranges between 200 °C and 350 °C. At these temperatures, the PG/VG matrix vaporizes, creating an aerosol that carries nicotine and volatile flavor compounds. The aerosol particle size distribution usually falls between 0.2 µm and 0.5 µm, allowing deep penetration into the respiratory tract.
2. Nicotine Pharmacokinetics in Vaping
2.1 Absorption Pathways
| Route | Approx. Bioavailability | Time to Peak Plasma Concentration |
|---|---|---|
| Pulmonary (inhalation) | 30‑40 % of inhaled dose | 5‑10 min |
| Oral (mouth‑to‑lung, “mouth hit”) | 10‑20 % | 15‑30 min |
| Dermal (skin contact with residue) | <5 % | N/A |
The rapid pulmonary absorption mirrors that of combustible cigarettes, but the overall nicotine delivery can vary widely depending on device power, e‑liquid concentration (often 3‑20 mg/mL in Australia), and puff duration. For devices like the IGET Bar Plus that can produce up to 6000 puffs, cumulative nicotine exposure may be substantial if used continuously throughout the day.
2.2 Metabolism
Nicotine is primarily metabolized in the liver by CYP2A6 into cotinine, which has a half‑life of ~ 16 hours. The presence of nicotine salts (common in modern disposables) can slightly slow the metabolism, giving users a smoother “buzz” with potentially lower peak spikes but prolonged exposure.
2.3 Cardiovascular Effects
- Acute increase in heart rate (5‑15 bpm) and systolic blood pressure (5‑10 mm Hg).
- Enhanced catecholamine release (epinephrine, norepinephrine) leading to vasoconstriction.
- Endothelial dysfunction reflected by reduced flow‑mediated dilation (FMD) within minutes of vaping.
While these changes are generally transient, chronic exposure has been linked to arterial stiffness and early atherosclerotic changes in animal models, raising concerns for long‑term cardiovascular risk.
3. Respiratory System – From the Throat to the Alveoli
3.1 Heat‑Generated Toxicants
Even at “low” coil temperatures, thermal decomposition of PG/VG can produce formaldehyde, acetaldehyde, and acrolein. A systematic review of 27 studies found that high‑power vaping (≥ 30 W) can generate formaldehyde‑hemiformal levels comparable to secondhand smoke, though typical low‑power use (≤ 15 W) keeps these compounds at significantly lower concentrations.
3.2 Inflammatory Response
- Cytokine Release: Vaping stimulates release of IL‑6, IL‑8, and TNF‑α from bronchial epithelial cells.
- Immune Cell Recruitment: Neutrophils and macrophages infiltrate airway tissue after repeated exposure to aerosol.
- Mucociliary Clearance: PG/VG can impair ciliary beat frequency, reducing the ability to clear mucus and toxins.
These mechanisms are thought to underpin vaping‑associated lung injury (EVALI), a condition first highlighted in 2019. While the majority of EVALI cases involved vitamin E acetate in THC‑containing products, pure nicotine aerosols have also been implicated in milder forms of airway irritation and chronic bronchitis.
3.3 Structural Changes
Animal studies demonstrate alveolar simplification and reduced surfactant production after chronic exposure to nicotine vapor. In humans, high‑resolution CT scans of long‑term vapers sometimes reveal sub‑clinical ground‑glass opacities or airway wall thickening, though the prevalence remains lower than among smokers.
4. Oral Health – The Mouth’s First Contact
4.1 Dental Enamel and Tooth Sensitivity
PG and VG are hygroscopic; prolonged exposure can dry out the oral mucosa, lowering saliva pH and promoting enamel demineralization. Flavored e‑liquids often contain acidic fruity additives that accelerate erosion.
4.2 Periodontal Disease
- Microbial Shifts: Vaping alters the balance of oral microbiota, favoring Porphyromonas gingivalis and Fusobacterium nucleatum, both linked to periodontitis.
- Inflammation: Elevated levels of matrix metalloproteinases (MMP‑8) have been detected in the gingival crevicular fluid of vapers.
4.3 Halitosis and Xerostomia
Reduced salivary flow and the presence of flavor residues contribute to persistent bad breath. Users of disposable devices such as the ALIBARBAR Bar often report a “dry mouth” sensation after multiple puffs.
5. Metabolic Effects – Weight, Insulin, and Hormones
5.1 Appetite Suppression
Nicotine stimulates pro‑opiomelanocortin (POMC) neurons in the hypothalamus, reducing hunger signals. Epidemiological data indicate that current vapers have a modestly lower BMI than non‑users, though the effect diminishes after cessation.
5.2 Glucose Homeostasis
Acute nicotine exposure raises blood glucose via catecholamine‑mediated glycogenolysis. Chronic usage may increase insulin resistance, as observed in rodent models where nicotine vapor led to a 20 % rise in HOMA‑IR after 12 weeks.
5.3 Hormonal Alterations
- Adrenal Cortex: Elevated cortisol in some vapers, potentially linking vaping to stress‑related pathways.
- Reproductive Hormones: In men, reduced testosterone and sperm motility have been noted in studies where participants used high‑nicotine (> 10 mg/mL) devices daily for three months.
6. Immune System Modulation
6.1 Innate Immunity
Vapor constituents can impair macrophage phagocytosis and neutrophil chemotaxis, reducing the lungs’ first line of defense against bacterial pathogens. This may partially explain the observed increase in respiratory infections among frequent vapers.
6.2 Adaptive Immunity
Research shows diminished IgA secretion in the nasal mucosa after chronic vaping, potentially compromising mucosal immunity. Additionally, nicotine’s immunosuppressive properties can down‑regulate T‑cell proliferation.
7. Pregnancy and Development – Risks to Mother and Fetus
7.1 Placental Transfer
Nicotine readily crosses the placenta, achieving fetal plasma concentrations up to 80 % of maternal levels. Studies in pregnant rats exposed to nicotine aerosol demonstrated reduced fetal weight and brain‑stem abnormalities.
7‑8. Human Observational Data
- Preterm Birth: A cohort of 1,200 pregnant vapers showed a 16 % higher odds ratio for preterm delivery compared with non‑smokers.
- Neurodevelopment: Preliminary neurocognitive testing at age 2 revealed lower language scores in children whose mothers used nicotine vapes during pregnancy.
Given these findings, health authorities worldwide advise pregnant women to avoid all nicotine‑containing products, including e‑cigarettes.
8. Comparative Toxicology – Vaping vs. Smoking
| Parameter | Combustible Cigarettes | E‑Cigarettes (nicotine only) |
|---|---|---|
| Tar | ~ 12 mg per cigarette | Near‑zero |
| Carbon Monoxide (CO) | 8‑20 ppm per puff | < 0.5 ppm |
| Formaldehyde | 5‑30 µg per puff | 0‑5 µg per puff (depends on power) |
| Nicotine Delivery | 0.8‑1.2 mg per cigarette | 0.5‑2 mg per puff (variable) |
| Risk of Lung Cancer | Strongly established | Inconclusive; reduced but not eliminated |
| Cardiovascular Stress | Acute spikes + chronic atherosclerosis | Acute spikes; long‑term data still emerging |
| Second‑hand Exposure | High (CO, tar) | Low to moderate (aerosol particles) |
Overall, e‑cigarettes appear less harmful than traditional cigarettes in many toxicological dimensions, yet they are not harmless. The risk reduction is heavily dependent on device type, usage pattern, and e‑liquid composition.
9. Regulatory Landscape in Australia
- Nicotine Importation: The Therapeutic Goods Administration (TGA) classifies nicotine as a prescription‑only medication. Consumers must obtain a medical prescription or rely on personal import limits (up to 3 months’ supply).
- Product Standards: Devices must comply with the TGO 110 standard, covering battery safety, labeling, and emissions limits.
- Advertising Restrictions: Direct marketing of nicotine‑containing e‑liquids is prohibited; only non‑nicotine products may be advertised publicly.
- Age Limits: Sale to anyone under 18 years is illegal. Retailers offering IGET and ALIBARBAR devices are required to verify age through robust ID checks.
These regulations aim to minimize youth uptake while allowing adult smokers an alternative pathway to reduced‑risk nicotine delivery.

- Maintain Device Hygiene – Clean the tank, coil, and mouthpiece weekly to avoid microbial growth and residue buildup.
- Seek Professional Guidance – If you experience persistent cough, chest pain, or worsening oral health, consult a healthcare provider experienced with vaping‑related issues.
Conclusion
E‑cigarettes occupy a nuanced position on the health spectrum: they present a lower‑risk alternative to combustible tobacco for adult smokers, yet they are not devoid of physiological impact. Nicotine continues to exert potent cardiovascular and metabolic effects, while the aerosol’s chemical constituents can provoke respiratory inflammation, impair oral health, and modulate immune function.
Brands such as IGET and ALIBARBAR demonstrate how thoughtful device engineering—enhanced battery life, ergonomic designs, and rigorous quality standards—can improve the user experience while adhering to Australian regulatory frameworks. Nonetheless, the long‑term consequences of chronic vaping remain incompletely understood, especially concerning cardiovascular disease progression and potential carcinogenicity.
For individuals contemplating a switch from cigarettes, vaping may indeed reduce exposure to tar, carbon monoxide, and numerous carcinogens. However, the safest option for overall health remains complete nicotine abstinence. If you choose to vape, employing the risk‑mitigation strategies outlined above can help minimize adverse outcomes while you enjoy the flavors and convenience that modern disposable devices offer.
