The harder the enforcement, the harder the drug – the iron law of prohibition – is alive and well in the U.S., unlike those who consume increasingly dangerous circulating drugs like xylazine (aka "tranq") and more powerful fentanyl analogs. Drs. Jeff Singer and Josh Bloom explain in an op-ed in The Daily Beast.

There's a codeine analog with a strange name: "Thebacon." How does one pronounce this? Is it useful? And are there other obscure chemicals with meat-containing names? And A Dreaded Chemistry Lesson From Hell (TM) for no extra charge.

The Manhattan Project to develop the bombs was one of the greatest scientific, technological, and logistical achievements in history. The bombs ended the war and saved millions of lives of combatants and civilians.

The eight cases of locally transmitted malaria recently reported in the U.S. – the first in 20 years – have elicited loony conspiracy theories about the cause. They're bunk.

Masking to prevent COVID infections has diminished drastically, even in healthcare settings, and there are already examples of its negative effects. Across-the-board abandonment of masking is premature: It is effective, inexpensive, not terribly inconvenient, and applicable to preventing airborne and droplet-spread infections in addition to COVID. Most important, it is in the best interest of staff, patients, and public health.

The drug, Leqembi, does not reverse symptoms. In patients in the early stages of Alzheimer's disease, it slowed cognitive and functional decline somewhat compared with placebo. The FDA’s approval of Leqembi is not the end of the Alzheimer’s journey, but it could be a way station. 

Discussions of “climate change” or “global warming” tend to focus on increasing temperatures in summer, especially the current run of severe heat waves.  The 85-page summary of the Intergovernmental Panel on Climate Change (IPCC) report mentions “winter” only once, the surname of one of the authors, but the adverse health effects of cold winters have long been recognized. Can the health benefits of warmer winters compensate for the damaging effects of hotter summers? 

The FDA is allowing women over-the-counter access to one brand of one form of birth control pill. But the agency should follow the advice of medical experts and let women exercise their right to self-medicate with all hormonal contraceptives.

While academics explore the bounty and pitfalls that Artificial Intelligence (AI) offers, and Big Tech continues to hype the possible over the actual, the feds seek to make regulations. Corporate healthcare, in all its forms, is fighting back. Should we be techno-optimists, Luddites, or somewhere in between?

Tori Bowie, a 2016 US Olympian, died from complications of childbirth; Serena Williams experienced a pulmonary embolism after delivery that was initially ignored. According to the World in Data, US maternal mortality per 100,000 live births lies “comfortably” less than in Grenada but more than in Latvia or Puerto Rico. Let’s get behind the headlines, and delve deeper into a “preventable” problem.

The World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) recently concluded that the popular artificial sweetener aspartame, widely used in foods and diet drinks, is “possibly carcinogenic to humans,” an alarming conclusion because aspartame is used in thousands of low-calorie products. However, another WHO organization, the Joint Expert Committee on Food Additives (JECFA), concluded that it is safe to consume aspartame. Can we make sense of the conflicting conclusions?

According to the common narrative, ultra-processed foods are evil, unhealthy, and unnatural. But a new contrarian study in the Journal of Nutrition demonstrates that a diet containing 91% ultra-processed foods was far healthier than the typical American diet and, get this, well aligned with Dietary Guidelines for Americans. When it comes to shaming and blaming UPFs, the emperor has no clothes.

Although Kansas' effort to prevent drug-impaired driving is admirable, the method the state is using to detect it is flawed. SoToxa, Abbott's hand-held analytical device can rapidly detect and identify common drugs in saliva but gives no information about the amount of drug present. I predict this will cause all kinds of problems

The FDA has finally allowed women to have access to one brand of one form of birth control. it’s time for them to follow the advice of the medical experts, and allow women access to all forms of hormonal contraceptives.

The FDA’s assault on vaping has yielded devastating consequences. Not only have millions of adults been denied legal access to low-risk vaping products they rely on to stay smoke-free, federal regulations are rapidly destroying thousands of jobs and billions of dollars worth of income, depriving ordinary Americans of their livelihoods.

As the COVID pandemic moves further into our rearview mirrors, questions have been raised about a more prolonged manifestation of COVID, Long COVID. Now, there seems to be a concern about more prolonged symptoms from the COVID vaccines; we can call it Long Vax. What do we know and don’t know?

A new health scare is brewing as reporters speculate about the cancer risk of consuming the sweetener sucralose. Is there any evidence behind the panic? No. A team of scientists recently argued that it's time for oil companies to pay reparations for causing climate change. Let's take a critical look at their claims.

In criminal law, intent is necessary before guilt can be proven. Even civil actions, like intentional torts, pivot on intentionality.  Until now, intention was determined based on circumstantial evidence, with some jury guesswork. But what if it were possible to demonstrate someone’s state of mind objectively? What if there were no hiding behind a baby face or angry denial?

I’m at an age where I see doctors frequently enough that I noticed that the masks are gone. Will a surge in influenza or COVID this fall and winter bring masks back for all, or has COVID given us something other than a one-size-fits-all approach?

Indian activist Vandana Shiva opposes the tools and practices of modern agriculture and science and advocates regressive policies that cause widespread malnourishment, famine, and death to the very people she claims to champion. And she's no friend of the environment, either. She should never be given a podium.

In late 2019 Betelgeuse, a star within the Orion constellation, grew dim, leading to speculation that its life might be at an end and it would become a supernova. The dimming, now felt due to “dust” and stellar activity obscuring our view, has resolved. Not so the concerns over Betelgeuse.

The CDC recently issued guidance related to breastfeeding for "transgender and nonbinary-gendered individuals." It may be the most absurd set of recommendations the agency has ever released.

“…body mass index, BMI, then, is a continuation of white supremacist embodiment norms, racializing fat phobia under the guise of clinical authority.” Quite an opening from an article in the AMA’s new Journal of Ethics. Stripped of its rhetoric, could it be true?
