Health Risks from Water Fluoridation are not just in RFK’s Head

“There is evidence that fluoride exposure has been associated with the diseases [and] disorders that RFK listed, but with caveats”

Water fluoridation has returned to the forefront of public policy debates thanks to environmental lawyer Robert F. Kennedy Jr. Kennedy is expected to have a role in the Department of Health and Human Services, giving his opinion more weight than ever.

In a post to X, Kennedy wrote, “On January 20, the Trump White House will advise all U.S. water systems to remove fluoride from public water. Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease.”

The post links to a High Wire video interview with lawyer Michael Connett, lead attorney in a successful case against the Environmental Protection Agency (EPA). Last September, Obama-appointed District Court Judge Edward Chen sided with Connett and mandated the EPA to more strictly regulate water fluoridation.

Chen’s ruling states, “In all, there is substantial and scientifically credible evidence establishing that fluoride poses a risk to human health; it is associated with a reduction in the IQ of children and is hazardous at dosages that are far too close to fluoride levels in the drinking water…”

Fluoride is a poisonous industrial byproduct, handled in its pure form by people in hazmat suits. Dealing with sodium fluoroacetate was an expense for the Aluminum Company of America before Edward Bernays helped turn it into a profitable venture. In the 1940s, Bernays, the father of modern public relations and nephew of psychoanalyst Sigmund Freud, used mass psychology and public health advocates to have fluoride put in drinking water. Fluoridation opponents were dismissed as kooks ever after.

The toxicology adage “The dose makes the poison” applies. Chemicals, including drugs, can benefit health in some respects but undermine it in others. Unfortunately, recent analysis suggests the “side effects” of fluoridation may outweigh its alleged benefits.

A recent analysis by Cochrane Reviews said water fluoridation may provide a slight dental benefit, but less so since the mid 70’s when manufacturers commonly added fluoride to toothpaste. Fluoride reverses or stops early tooth decay by remineralizing teeth, making them stronger. It also reduces bacteria’s ability to make acids that cause decay.

Fluoride capsules have little effect on teeth, which suggests its main positive effect is topical (meaning by direct contact). An obvious question follows: if fluoride of roughly one part per million passing over the teeth before swallowing, what is its effect during digestion or bodily storage? After all half of fluoride is passed through urine, while the remainder is stored in the body.

In 2020 The Institute of Technology and Business in the Czech Republic made a six-article issue dedicated to the mechanisms of fluoride toxicity. One explained in the abstract that “fluoride is an enzymatic poison, inducing oxidative stress, hormonal disruptions, and neurotoxicity.” The toxic effects were magnified when trace amounts of aluminum were present, and “might contribute to unexpected epidemics in the future.”

Sleeplessness, hypothyroidism, and autism to conditions linked to fluoride consumption, whether through natural sources or water fluoridation. The risks were found through statistical studies comparing health issues in water fluoridated and non-fluoridated areas, biochemical analysis, and human and animal studies.

“We concur with the conclusions of many authors over the world that fluoride neurotoxicity is a serious risk associated with elevated fluoride exposure… […] Fluoride toxicity is a slow, hidden process. Evolving evidence should inspire scientists and health authorities to re-evaluate claims about the safety of fluoride…”

In 2019, researchers from Canadian and U.S. universities tested over 500 Canadian women throughout their pregnancies for fluoride levels in their urine. Their study, published in the Journal of the American Medical Association (JAMA), found that for each milligram of fluoride per litre in the mother’s urine, IQ dropped 4.5 points in their male children tested at ages of three to four years.

Christine Till, a professor in the Department of Psychology at York University in Toronto, told CNN, “At a population level, that’s a big shift. That translates to millions of IQ levels lost.”

Ashley Malin, an assistant professor in the University of Florida’s Epidemiology Department, had similar findings in her Florida study, published in JAMA in 2024.

“There is evidence that fluoride exposure has been associated with the diseases [and] disorders that RFK listed, but with caveats,” Malin told the Virginia Mercury in a recent article.

“Aside from fluoride’s impacts on neurodevelopment, I think that there is more that we don’t know about health effects of low-level fluoride exposure than what we do know, particularly for adult health outcomes,” Malin added.

In August, the National Toxicology Program (NTP) in the United States found that fluoride levels higher than 1.5 mg/L (the highest acceptable level in Canada) are associated with lower IQs in children. The NTP said there is insufficient evidence to conclude that there are similar risks at the recommended level of 0.7 mg/L.

Montreal recently ended its water fluoridation and hopefully other cities will follow. Only a misguided nanny state would poison young minds and old bones for the sake of people who don’t brush their teeth.

Canada’s Leadership Vacuum Fueling a National Crisis

Published on

From the Frontier Centre for Public Policy

By David Leis

Canada is at a breaking point. Weak border security, unchecked organized crime, and rampant foreign interference have left the country dangerously exposed to threats that jeopardize its safety, economy, and sovereignty. Under Prime Minister Justin Trudeau’s leadership, these challenges have escalated to unprecedented levels, and no meaningful action has been taken to address them.

In British Columbia, a mother of two recently shared how the fentanyl crisis has ravaged her community. She spoke of losing friends and neighbours to overdoses, while her own family lives in fear of growing gang activity. Her story illustrates the human cost of systemic inaction and highlights the devastating consequences of a government unable to protect its people. It is a tragic reality mirrored in communities across the country, from urban centres to small towns, where drugs and crime are taking a growing toll.

Canada’s border management, a critical first line of defence, is failing to stem the tide of illicit goods and activities. The Canada Border Services Agency inspects less than two per cent of shipping containers entering the country, leaving ports like Vancouver vulnerable to transnational crime. According to the Cullen Commission, billions of dollars are laundered annually in British Columbia, often through casinos and real estate linked to organized crime. Transparency International’s 2022 report ranked Canada among the worst in the G7 for anti-money laundering enforcement, underlining systemic failures.

Weak border controls are exacerbating the fentanyl crisis. Precursor chemicals flow into Canada largely unchecked, often disguised as legitimate imports. Provincial officials in British Columbia have acknowledged the need for tighter regulations on pill presses, but federal laws remain inconsistent. The consequences are staggering: over 34,000 Canadians have died of opioid overdoses since 2016, according to Health Canada. These are not just numbers; they represent families shattered and communities in mourning. Yet, the federal government continues to respond with piecemeal measures instead of a comprehensive national strategy.

Concerns over foreign interference add another dimension to Canada’s vulnerability. Weak borders and lax enforcement also provide fertile ground for foreign actors to exploit. The recent inquiry into election interference revealed disturbing levels of meddling, with CSIS identifying instances of Chinese state funding for federal candidates. Hybrid warfare tactics – including cyberattacks, economic manipulation, and political interference – are well-documented. These activities undermine Canada’s sovereignty and erode trust in its democratic institutions.

International partners, particularly the United States, are taking notice. Canada’s largest trading partner has grown increasingly frustrated with these vulnerabilities. Under a potential Trump administration, Canada could face severe economic repercussions, including tariffs, if it does not address its security deficiencies. A report from the Global Initiative Against Transnational Organized Crime labelled Canada a “safe zone” for transnational crime, citing weak enforcement and limited co-ordination among intelligence agencies. Such critiques directly challenge Canada’s reputation and its role as a trusted ally.

Canada’s aging infrastructure compounds these security failures. A 2023 report from Statistics Canada revealed that nearly 40 per cent of the country’s infrastructure is nearing the end of its useful life. Ports, highways, and public utilities – critical for trade and national security – are underfunded and rapidly deteriorating. This hampers economic competitiveness and leaves Canada ill prepared to secure its supply chains. These failings highlight a broader issue: the government’s reluctance to prioritize foundational investments that ensure long-term stability.

Meanwhile, Canada’s regulatory framework struggles to keep pace with modern threats. The country lacks effective oversight to combat money laundering, cyberattacks, and supply chain exploitation. Organized crime and illicit trade drain billions from the economy every year. Weak border controls have made Canada a transit point for everything from drugs to counterfeit goods. Provincial attempts at regulation, like in British Columbia, have helped somewhat, but federal legislation has yet to catch up.

Canada’s challenges didn’t emerge overnight. They are the result of decades of underinvestment in security, weak enforcement, and a lack of political will. While the Trudeau government has failed to address these issues, previous administrations are responsible for creating the conditions that allowed them to fester.

However, the current government bears responsibility for the lack of urgency in the face of escalating crises. Performative policies, like token GST rebates, do little to address systemic issues. The Trudeau government has failed to modernize Canada’s security apparatus, prioritizing political optics over substantive reform.

Canada cannot afford to remain passive in the face of these mounting threats. The government must decisively modernize border security, combat organized crime, and confront foreign interference with meaningful legislation and enforcement. Countries like Australia have successfully implemented advanced port screening and stricter anti-money laundering laws to address similar issues. Canada must follow suit to regain control of its borders and restore trust in its institutions.

The stakes couldn’t be higher. Every uninspected container ship, every fentanyl overdose, and every election left vulnerable to interference represents a failure of leadership. The mother in B.C., fearing for her children’s future, is not alone – she represents countless Canadians who feel abandoned by a government unwilling to act. Her voice, and others like hers, demand attention.

This is no longer about politics or optics; it’s about safeguarding the nation’s future. The time for complacency has passed. Canada’s security, prosperity, and sovereignty depend on immediate, decisive leadership.

Anything less is unacceptable.

Global Warming Predictions of Doom Are Dubious

Published on

From the Frontier Centre for Public Policy

By Ian Madsen

What if the scariest climate predictions are more fiction than fact?

The International Panel on Climate Change (IPCC) aims to highlight the urgent threats climate change poses. It projects severe consequences, including longer and more intense urban heat waves, as the World Resources Institute noted, along with increased storms, floods, and crop failures. IPCC claims that our current path leads to a temperature increase of at least three degrees Celsius above pre-industrial (circa 1750-1850) levels if the world does not drastically reduce carbon dioxide or just carbon emissions. However, this assessment and the attendant predictions are dubious.

The first uncertainty is the pre-industrial global temperatures. There were no precise thermometers at random sites or in major towns until late in the 19th century. Therefore, researchers use ice cores and lake and sea sediments as proxies. The U.S. National Aeronautics and Space Administration admits that pre-1880 data are limited. It provides many examples showing how even modern temperatures can be incomparable from region to region and from past to present and consequently are adjusted to approximate comparability.

What cannot be explained away is the Medieval Warm Period, which lasted from about 800 AD to around 1300 AD, and the subsequent cooling period that ‘bottomed’ about 1700 AD called the Little Ice Age. Human activity did not cause either one, and they were not merely regional phenomena confined to the North Atlantic and Western Europe. In the Middle Ages, Vikings settled in Greenland and were able to grow crops. The weather cooled dramatically, and they abandoned their colonies in the 15th century. During the Little Ice Age, there were many crop failures and famines in Europe, and the river Thames reliably froze over, with ice thick enough to hold winter fairs on.

Temperatures did not rise significantly until well into the 19th century. Suppose the recent temperature increase between one and one and one-half degrees Celsius is correct. This is only a third of the way toward a more tolerable  (i.e., more livable, with less disease and fewer cold-related deaths) climate and cannot be termed “global boiling,” as the Secretary-General of the United Nations called it in 2023.

At three or more degrees of warming, IPCC researchers (“Climate Change 2023 Synthesis Report:  Summary for Policymakers Sixth Assessment Report,” “AR6” pp. 15-16) have “high confidence” in more severe hurricanes, typhoons and cyclones; large floods; deadlier heatwaves and droughts; lower glacier-fed river flow; and lower crop yields.

Yet, their predictions are vague and generalized. So far, there are few signs that these calamities are increasing in frequency or intensity – hurricanes, cyclones, and typhoons are not. Indeed, humanity is coping well: The UN’s Food and Agriculture Organization observed that 2024 grain production was the second-highest on record.

Here are a few erroneous predictions the New American found: the United Nations Environmental Program (UNEP)’s 2005 warning of 50 million climate refugees by 2010; the University of East Anglia’s 2000 prediction that the United Kingdom would rarely have snow in winter; and several early-2000s prognostications of the Arctic Ocean being ice-free in summer by 2016 – none has happened. A critique from May of 2020 of the thirty-eight models used to predict futures observed that the predictions of the amalgamated model used by the IPCC consistently and substantially overestimated actual warming.

Longer and hotter heat waves in cities are not the end of the world. They are unpleasant but manageable. Practical methods of urban cooling are spreading globally. Heat-related deaths are still far fewer than those from cold (by a ten-to-one ratio). If it gets hotter occasionally, humanity can and will survive.
