A Tiny State Just Banned a Parkinson’s-Causing Chemical. The EPA Is Hiding.

You probably don’t know what paraquat is. But it might already be in your food, your water, your soil. And now a growing body of evidence links it directly to Parkinson’s disease — a progressive, incurable neurological condition that destroys the brain’s ability to control movement.

Vermont just became the first state to ban it. And the reaction from the EPA? Silence. Indifference. A shrug that says: we’ll get to it in 20 years.

Let’s be clear about what’s happening here. Vermont doesn’t even use much paraquat. It’s a tiny, non-agricultural state. The ban isn’t about Vermont’s fields — it’s about sending a signal. When a state with almost no skin in the game bans a chemical, it’s not a policy decision. It’s a warning shot.

Paraquat is cheap, effective, and brutally toxic. It’s been linked to Parkinson’s in multiple studies, including a 2022 meta-analysis that found a 2.5 times higher risk for farmers exposed to it. The chemical is already banned in 32 countries, including China and the entire European Union. The US? Still legal. Still sprayed. Still sold by companies like Syngenta and Chevron, who have spent millions fighting lawsuits from farmers who developed Parkinson’s.

Here’s the part that should make you angry: the EPA has known about the risks for decades. Internal documents show that as early as the 1980s, the agency flagged paraquat as a potential trigger for Parkinson’s. But instead of acting, they kicked the can. They commissioned studies. They delayed reviews. They let the chemical stay on the market while the evidence piled up.

You’ve probably noticed this pattern before. It’s the same story with glyphosate, with atrazine, with any chemical that brings in billions in revenue. Federal regulators don’t ban things until the public pressure becomes unbearable. So states are starting to do the work themselves.

Vermont’s ban is a masterclass in strategic sovereignty. By using its health and safety powers, the state is creating a pressure valve. Once one state bans it, others will follow. California, New York, and Massachusetts are already considering similar bills. And when enough states act, the EPA has two choices: adopt a national ban, or face a patchwork of regulations that makes compliance impossible for farmers and chemical companies.

This is the twist most people miss. The fight over paraquat isn’t really about Vermont. It’s about forcing the federal government to finally do its job. State-level bans are the most effective weapon we have against regulatory capture. They turn a slow-moving bureaucracy into a cornered animal.

But here’s the uncomfortable truth: the people who will suffer most from this ban are small farmers. Paraquat is one of the cheapest weedkillers on the market. Without it, they’ll have to spend more on alternatives — or lose yields. The chemical industry is already spinning this as a case of “elite environmentalists” hurting rural communities.

That framing is a lie. The real cost is the one we’re already paying: the health of farmers, farmworkers, and anyone who lives near agricultural land. Parkinson’s doesn’t just affect the person who gets it. It destroys families, drains savings, and costs the healthcare system hundreds of thousands per patient. The question isn’t whether we can afford to ban paraquat. It’s whether we can afford not to.

What happens next depends on how loud we get. Vermont has shown that a single state can break the logjam. Now it’s up to the rest of us to push harder. Call your state representatives. Ask them if they’re watching Vermont. And don’t let them tell you it’s a local issue — when a chemical causes Parkinson’s, it’s everyone’s problem.
