Learning from the Past
Throughout history, industries and regulators have often assured the public that new products and technologies were safe—only to be proven dangerously wrong years or even decades later.
From tobacco to asbestos, leaded gasoline to certain pharmaceuticals, industries have repeatedly downplayed risks until undeniable harm forced change. The speed of regulatory responses varied—tobacco regulations took decades to materialize, asbestos bans were staggered across different countries, and leaded gasoline was phased out slowly despite strong early evidence of harm. These delays, often fueled by industry influence, resulted in widespread public health consequences.
Regulations were eventually enacted, but only after overwhelming evidence and public outcry. Tobacco advertising bans and warning labels emerged in the 1960s and 1970s, asbestos regulations tightened globally in the 1980s and 1990s, leaded gasoline was phased out starting in the 1970s, and dangerous pharmaceuticals were only recalled after widespread harm had already occurred.
The precautionary principle suggests that instead of waiting for absolute proof of harm, we should take protective action when there is reasonable scientific concern. Yet, with 5G, the world is once again moving forward without long-term safety data. Are we repeating history?
Case Studies: The Price of Waiting
1. Tobacco: The Science Was There, But Industry Fought Back
For decades, cigarette companies funded research to discredit studies linking smoking to lung cancer. Despite mounting evidence as early as the 1940s, the tobacco industry successfully delayed regulations for nearly half a century.
Documents later revealed how companies manipulated scientific discourse, casting doubt where there was none.
Lesson for 5G: The existence of conflicting studies does not mean there is no risk—it often means industry influence is at play.
2. Asbestos: Known Risks, Ignored Warnings
As early as the 1920s, researchers linked asbestos exposure to severe lung diseases, including mesothelioma. Despite clear medical evidence, industries continued to use asbestos in construction, shipbuilding, and consumer products.
It took decades before governments acted, leading to countless preventable deaths.
Lesson for 5G: Just because harm isn’t immediately visible doesn’t mean it isn’t happening. Chronic conditions often take years to emerge.
3. Lead in Gasoline: Profit Over Public Health
Lead was added to gasoline in the 1920s to improve engine performance, despite early studies linking lead exposure to neurological damage.
Industry-backed research dismissed the concerns, and it took until the 1970s for bans to begin, after generations of children suffered irreversible cognitive damage.
Lesson for 5G: The burden of proof should not be on the public to demonstrate harm—it should be on the industry to prove safety before widespread deployment.
4. The Pharmaceutical Industry: A Long History of “Safe” Drugs Gone Wrong
Drugs such as thalidomide (which caused birth defects) and Vioxx (linked to fatal heart attacks) were widely prescribed before their dangers became clear.
Pharmaceutical companies often push products based on short-term safety studies, only for long-term effects to surface later.
Lesson for 5G: Short-term studies are not enough. Rigorous, independent, and long-term research is necessary before declaring any technology safe.
5G: The Next Chapter?
Unlike tobacco or pharmaceuticals, 5G is not a chemical exposure—it’s an environmental exposure to electromagnetic radiation. But does that make it less dangerous? We don’t fully know, and that’s the problem.
Unlike previous generations of wireless technology, 5G uses higher-frequency waves, which allow for faster data transmission but have a shorter range. As a result, significantly more small cell towers must be placed closer to homes, schools, and workplaces to maintain reliable connectivity.
What we do know:
- The World Health Organization (WHO) has classified radiofrequency (RF) radiation as a possible carcinogen (Group 2B), the same category as lead and DDT. This classification means there is some evidence suggesting a potential link to cancer, but it does not confirm a definite risk. Further research is needed to determine the long-term health effects of prolonged exposure.
- Studies on long-term exposure to low-level radiation are still inconclusive. A 2021 report published in Environmental Research found that while some studies indicate potential biological effects, results are inconsistent and more long-term, independent studies are needed. Similarly, the U.S. National Toxicology Program (NTP) conducted a large-scale study on radiofrequency radiation exposure in rats, which found evidence of increased tumor risks, though debates continue over its applicability to humans.
- Industry-funded research overwhelmingly supports 5G safety, while independently funded studies more frequently report biological effects (see The 5G Safety Question: When Industry Funds the Science, Can We Trust the Results?).
Yet, despite these concerns, 5G is being rolled out without applying the precautionary principle.
Why Aren’t We Acting with Caution?
Governments and industries often resist precautionary measures because they slow down economic growth and disrupt corporate profits.
In the case of 5G:
- Telecom companies stand to profit enormously from 5G expansion.
- Governments benefit from the technological advancements and infrastructure development.
- Critics and concerned scientists are often dismissed as alarmists, just as they were in the past with tobacco, lead, and asbestos. Regulatory bodies such as the WHO and the FCC argue that existing exposure limits are sufficient to protect public health. They cite studies that indicate no conclusive evidence of harm from current 5G radiation levels. However, independent researchers point out that many of these studies are short-term and industry-funded, emphasizing the need for further investigation.
For example, Dr. Devra Davis, an epidemiologist and founder of the Environmental Health Trust, has been vocal about the potential health risks of wireless radiation, yet her concerns are frequently marginalized in mainstream discussions. Similarly, the BioInitiative Report, a compilation of independent research on electromagnetic radiation, has been largely dismissed by regulatory agencies despite being based on peer-reviewed studies.
The Precautionary Principle in Action: Countries That Are Taking It Seriously
While many nations are embracing 5G without hesitation, others are applying precautionary measures.
Some of these actions have led to policy changes, further research initiatives, or stricter radiation limits. Countries such as Switzerland and Belgium have paused or restricted 5G expansion pending additional studies, showing that regulatory caution is possible when public health concerns are prioritized.
- Switzerland: Has delayed 5G expansion due to health concerns.
- Belgium: Has stricter radiation limits and paused 5G rollout for further study.
- France: Has banned Wi-Fi in nurseries and limited wireless exposure for children.
These nations recognize that waiting for undeniable proof of harm is not responsible policy-making.
Conclusion: What If We’re Wrong?
The precautionary principle exists because history has shown us that industries often prioritize profit over public health, though there have been cases where proactive measures were taken.
For example, some pharmaceutical companies have voluntarily pulled dangerous drugs off the market before regulatory intervention, and auto manufacturers have recalled vehicles due to safety concerns. However, in many cases, decisive action has only come after undeniable harm was exposed.
So, should we wait for proof of harm? Or should we demand more transparency, independent research, and safety precautions before exposing billions of people to a technology whose long-term effects are still unknown?
If history has taught us anything, it’s that waiting for undeniable proof can come at an unbearable cost.
