The myth of quitting

Vaping is often promoted as a tool to help people stop smoking, yet the data tells a different story. Although 85% of e-cigarette users report starting vaping to quit cigarettes, a 2013 study across four countries published in the American Journal of Preventive Medicine found they were no more likely to quit than those who never vaped. In fact, reports show that vaping often reduces the likelihood of quitting altogether, with around 70% of users becoming dual users—continuing to smoke while vaping.

What’s actually in the vapour

A 2017 Harvard study analysing 24 flavoured e-cigarette brands found that every single one contained at least one aldehyde or flavouring chemical listed as “High Priority” by FEMA or classified by the FDA as Harmful or Potentially Harmful. Despite this, these products are inhaled repeatedly every day.

We also don’t fully understand how common ingredients—propylene glycol, vegetable glycerin, flavourings, and other additives—behave when heated and aerosolised, especially when used 20 to 30 times a day beyond their original FDA approval context.

‍

Lung injury and toxic exposure

The risks became highly visible during the 2019 outbreak of vaping-associated lung injuries, which resulted in 2,807 hospitalisations and 68 deaths in under a year. One major contributing factor was vitamin E acetate—an additive whose harmless-sounding name masked its severe effects when inhaled.

Research from Johns Hopkins examining 56 e-cigarette devices found that many produced aerosols containing potentially unsafe levels of lead, chromium, manganese, and nickel. These metals originate from heated metal coils and are linked to lung, liver, immune, cardiovascular, and neurological damage, as well as certain cancers. The danger is amplified by ethyl maltol, a common artificial sweetener shown to facilitate the transport of heavy metals into cells.

‍

Cardiovascular and clotting risks

Vaping also exposes users to high concentrations of ultra-fine particles and toxins at levels comparable to conventional cigarettes. These particles activate platelets, increasing their tendency to clump together—an important contributor to clot formation and cardiovascular disease.

Research from Poland suggests that chemicals such as acrolein and formaldehyde, created during e-liquid heating, accelerate arterial hardening and narrowing by more than 1.6 times. Studies from the University of California, San Francisco found that daily e-cigarette use doubles the risk of heart attack, while dual users face a fivefold increase compared to non-smokers.

‍

Hormones, fertility, and pregnancy

The effects extend beyond the lungs and heart. A 2022 study found that vaping doubles the risk of erectile dysfunction in men aged 20 and over. A separate 2020 study of 1,221 men showed a 34% reduction in total sperm count among e-cigarette users compared to non-users.

E-cigarettes contain endocrine-disrupting compounds capable of interfering with hormonal balance and reproductive function. In women, a large study involving 71,940 participants found that unfavourable birth outcomes increased by 62% among those who used e-cigarettes during pregnancy.

‍

Immune suppression and hidden contaminants

Vaping weakens the body’s ability to fight infections. A 2018 study published in BMJ Thorax showed that e-cigarette vapour damages alveolar macrophages—key immune cells responsible for clearing pathogens, toxins, and allergens from the lungs.

Additional concerns come from contamination: an analysis of the ten top-selling U.S. brands detected endotoxins above the limit of detection in 23% of samples tested, adding another layer of inflammatory risk.

‍

Beyond health: society and the environment

Beyond physiology, there is a broader cost. The argument that vaping benefits society is weak when considering its environmental impact. Each disposable vape contains a lithium-ion battery; in the UK alone, the lithium discarded annually in vapes could produce around 1,200 electric vehicle batteries.

On a social level, vaping increasingly functions as an emotional crutch—an “adult pacifier” that outsources stress regulation and potentially disrupts brain chemistry and hormonal balance rather than addressing underlying causes.

‍

The real experiment

E-cigarette use continues to grow rapidly, while robust long-term research on its health effects remains limited. What we do know already points to serious risks—many of which mirror or compound those of smoking itself.

Don’t be society’s guinea pig. It’s time to confront the dark side of vaping.

In a meta-analysis assessing the mineral intake of approximately 3,000 women. It found that eating an iron-rich diet (20mg per day) was linked to a 30-40% lower risk of developing premenstrual syndrome when compared to the lowest intake of iron (around 10mg per day) (Am J Epidemiol. 2013 May).

Menstruating women lose around 40% more iron per day when compared to men, with some studies stating how heavy menstrual bleeding is one of the leading causes of anemia in the developed world (Liu Z, et al. 2007).

The National Health and Nutrition Examination Survey indicates that 12-16% of non-pregnant women (aged 16-49 years) have iron deficiency, with 2-4% having anemia.

Increasing iron intake through diet and supplementation for two months has been shown to reduce PMS symptoms considerably in all anemic women (Mitesh Sinha et al. 2013).

A defining moment in human health

We are standing at the edge of a defining moment in human history — one that will reshape how health is understood, managed, and lived. Most practitioners won’t see it coming until it’s already here. The pace of change is no longer linear; it’s accelerating at a parabolic rate.

Over the next ten years, healthcare will undergo a larger transformation than it has in the past two hundred. What once took generations to evolve will soon happen within a single career span.

‍

Why the next leap will eclipse the last 200 years

In the 1850s, global life expectancy hovered around 35 to 40 years. In industrial cities such as Manchester, it was recorded as low as 26. Up to 40% of children died before the age of five. Since then, humanity has doubled its average lifespan — one of the greatest achievements in modern history.

But that magnitude of progress will soon appear slow compared to what lies ahead. To understand why, we must look at how medicine has actually evolved — not as a straight line, but as a series of paradigm shifts.

‍

Medicine has never moved in a straight line

Medicine does not evolve gradually. It moves through distinct eras, each defined by its dominant questions, tools, and limitations. Every era solves the problems of its time — and creates the blind spots of the next.

‍

Medicine 1.0: survival through intervention

The age of infection and emergency care (1800s–1950s)

The first modern era of medicine was built around one core mission: survival. Its philosophy was direct and uncompromising — find the problem, cut it out, kill the pathogen. The focus was acute illness, trauma, and infectious disease. Surgery, antibiotics, vaccines, early imaging, and public health measures transformed mortality rates almost overnight.

Breakthroughs such as germ theory, penicillin, antisepsis, and sanitation saved millions of lives. Yet this era had little understanding of long-term health. There was no framework for chronic disease, prevention, or personalisation. Medicine 1.0 was exceptional in emergencies, but largely blind to the slow decline of health over time.

‍

Medicine 2.0: managing disease, not health

The rise of chronic disease frameworks (1950s–2010s)

As life expectancy increased, the medical challenge shifted. Infectious disease gave way to chronic illness. Medicine 2.0 emerged with a new goal: management. Cardiovascular disease, diabetes, cancer, and mental health disorders became the dominant focus.

Pharmaceuticals, specialist referrals, evidence-based medicine, and large clinical trials defined this era. Disease was framed as isolated dysfunction within individual organ systems. While imaging, surgical techniques, and electronic health records advanced rapidly, care became fragmented. Poly-pharmacy increased, symptoms were suppressed rather than resolved, and patients often cycled endlessly through the system.

Medicine 2.0 kept people alive — but rarely helped them thrive.

‍

Medicine 3.0: personalisation, prevention, and patterns

From symptoms to systems (2010s–2025)

The limitations of chronic disease management gave rise to a new way of thinking. Medicine 3.0 reframed health as a dynamic, interconnected system shaped by genetics, environment, lifestyle, and time. The focus shifted toward root causes, prevention, and optimisation.

Functional blood work, genomics, microbiome testing, wearables, and systems biology expanded what was possible. Practitioners began looking for patterns rather than isolated markers. Precision nutrition and functional reference ranges replaced one-size-fits-all recommendations.

Yet this era introduced new challenges. Data became abundant but scattered. Interpretation demanded high cognitive load. Standards varied widely, access remained inconsistent, and outcomes depended heavily on practitioner experience. While powerful, Medicine 3.0 was difficult to scale.

Many believe this is the peak of modern healthcare.

‍

Why medicine 3.0 is not the end point

Despite its advances, Medicine 3.0 still relies on humans to manually integrate overwhelming amounts of data, make predictions, and adjust protocols over time. It improved insight — but not intelligence. It offered tools — but not true systems.

The next era changes that entirely.

‍

Medicine 4.0: intelligence, automation, and decentralised health

Predictive, adaptive, and continuously evolving care (2025–2040+)

Medicine 4.0 represents a fundamental shift in how health is defined and managed. Health becomes a continuously evolving dataset, updated in real time across all stages of life. The focus moves from reaction to prediction, from static plans to adaptive systems, from intervention to self-correction.

Artificial intelligence, machine learning, digital twins, predictive analytics platforms, continuous multi-biomarker wearables, synthetic biology, and autonomous medical systems will allow health trajectories to be forecast before disease manifests. Diagnostics will become ambient. Treatment will adapt dynamically. Biology itself becomes increasingly programmable.

But this transformation comes with real challenges — data privacy, equity, over-reliance on technology, loss of human connection, and the risk of eroding individual agency. Intelligence must be guided, not blindly trusted.

‍

Building the infrastructure for medicine 4.0

This is where MyHealthPrac enters — not as a response to Medicine 4.0, but as an early foundation for it.

MyHealthPrac is a decentralised health management system designed to translate complexity into clarity. Built on over a decade of research, line-by-line journal reviews, and clinically informed logic, it transforms vast amounts of health data into actionable, root-cause solutions. Hard-coded algorithms, pattern recognition, and predictive frameworks allow practitioners to move beyond interpretation and into intelligence.

This is not theory. It is not a distant vision.

‍

Not the future of health — the next standard

Medicine 4.0 is not coming someday. It is arriving now. And the systems built today will determine whether this new era empowers practitioners and individuals — or overwhelms them.

MyHealthPrac is being built to lead that transition.
