Drug Legalization—The Answer to Our Overdose...

ACSH Science Dispatch ·

2025/09/09

“The stricter the law enforcement, the more dangerous the drug.” That’s how ACSH advisor and Cato Institute senior fellow Dr. Jeffrey Singer describes the iron law of prohibition, which he argues is driving America’s overdose epidemic. How do we reverse this alarming trend? Legalize all drugs. Dr. Singer joins us on a special episode of Science Dispatch to make that case.

Nitazenes—The Latest Illegal Opioids Wreaking Havoc...

ACSH Science Dispatch ·

2025/09/02

The use of a newer class of opioids, nitazenes, is growing across the US. Once rarely seen in illicit markets before 2019, the drugs have been found on nearly every continent at this point. Their elevated potency—250 to 900 times stronger than morphine for the most common nitazene—makes them far deadlier than heroin and fentanyl. Can we slow or stop the use of these opioids before they do more damage?

2025/08/28

Eating more calories earlier in the day may improve your insulin sensitivity, boosting your metabolic health and aiding weight management. Was "breakfast like a king, dinner like a pauper" right all along? Maybe. Recent genetics research might help validate this age-old nutritional wisdom.

Americans are regularly exposed to low levels of radiation during CT scans, fueling media speculation that this routine medical procedure is driving a cancer epidemic. Is there any truth to the CT scan-cancer association? Let's look at the data.

2025/08/21

Health and Human Services Secretary Robert F. Kennedy, Jr. is once again warning about the supposed dangers posed by mercury-containing vaccines. "I’m proud to finally deliver on a long-overdue promise: protecting our most vulnerable from unnecessary mercury exposure," he tweeted in early August. Kennedy was celebrating the removal of the preservative thimerosal from a small fraction of seasonal flu vaccines. The problem? He bungled basic chemistry in his rush to (once again) badmouth

2025/08/18

A growing body of research suggests that your gut microbiome can influence your health in a variety of subtle but important ways, and the foods you consume can have an upstream effect on the health of these trillions of microbes residing in your digestive system. An ACSH reader asks whether the widely used sweetener high fructose corn syrup should be avoided for that reason. Let's take a look.

Should We Urge Adult Smokers To Vape? Yes

2025/08/12

Smoking kills hundreds of thousands of Americans annually. As this death toll mounts, studies continue to show that nicotine vaping is significantly less harmful than smoking and far more effective than FDA-approved cessation therapies like nicotine gum. Why, then, do so many public health experts malign vaping as a threat? Let's take a closer look

Gun Control Debate Won't Solve Our Violent Crime Problem

ACSH Science Dispatch ·

2025/08/04

America's political debate over gun violence is a perennial food fight about the ethics of restricting access to firearms. While this makes for entertaining news clips on X, it doesn't get to the heart of the problem—namely that gun violence isn't monolithic. Some populations are more likely to commit homicide while others are more inclined to suicide. Stemming the country's violent streak requires a more nuanced approach. What could that look like?

2025/07/29

The White House recently disclosed that President Trump experiences chronic venous insufficiency, possibly intended to head off concerns that he suffers from a serious age-related health condition that could impair his ability to govern. This raises an important question: are high-level government officials entitled to medical privacy when their illnesses could affect their decision-making ability?

Will chronic cardio or regular weight-lifting sessions add years to your life? Conventional wisdom says "yes," though emerging research suggests that your exercise habits and your lifespan are more heavily influenced by your genetics than previously thought. Let's untangle the latest knot in the nature vs. nurture debate.

2025/07/16

Have we discovered the ideal source of energy? A recent study in Nature describes a newly synthesized chemical called hexanitrogen. Containing no carbon, it produces zero greenhouse emissions and decomposes into pure nitrogen. But...there's a catch. Is this a groundbreaking rocket fuel, or just cool chemistry that will be confined to the laboratory? Let's discuss.

A team of unsuspecting lawyers asked us to help promote their litigation targeting baby food makers, falsely alleging their products contain harmful levels of heavy metals.

Kidney stones are excruciatingly miserable, causing intense, unrelenting pain—often described as worse than childbirth. These hard mineral deposits form in the kidneys and can lodge in the urinary tract, causing sharp, stabbing sensations in the back or abdomen. Here's perhaps the worse chemistry lesson you'll ever learn.

GLP-1 drugs like Ozempic are transforming weight loss and diabetes management. But no good deed goes unpunished, and the manufacturers of these medicines now face a wave of lawsuits, with plaintiffs claiming they weren't warned about rare but sometimes serious side effects.

Scientific Consensus—A Concept Past Its Expiration Date?

ACSH Science Dispatch ·

2025/05/21

Science thrives on challenge, not conformity. Many scientists would agree with that statement, yet they often equate truth with expert consensus, at least when talking to the public. Since scientific disputes are really settled by evidence and not a show of hands, perhaps it's time for experts to abandon consensus and focus on a more accurate concept—convergence.

2025/05/13

The COVID-19 pandemic exposed systemic weaknesses in our disaster preparedness infrastructure. Despite prior warnings, politics and apathy nurtured a response system that prioritized appearances—e.g., a national stockpile of rotting N-95 masks—over effective interventions. Perverse incentives encouraged officials to drag their feet when time was short, a failure leading to poor coordination and resource allocation that couldn't counter a global viral threat. We desperately need reforms that will

'Mustard Mathmagic'—Hot Dogs Still Don't Cause Cancer

ACSH Science Dispatch ·

2025/05/05

The perennial vegan worrywarts at Physicians Committee for Responsible Medicine (PCRM) have once again warned that grilled hot dogs increase colorectal cancer risk. But this potential harm is wildly overstated—as it has been since it first emerged from the dark recesses of nutritional epidemiology many years ago. Your absolute risk of colorectal cancer remains quite low, and the occasional ballpark hot dog probably doesn't move the needle in either direction. Let's take a closer look.
