SHOULD LEGAL MARIJUANA HAVE A WARNING LABEL?

For millions of Americans April 20, or 4/20 is a national holiday intended to celebrate a drug that remains illegal at the Federal level in the U.S. At the State level, it is a totally different story. Almost 90% of Americans (approximately 300 million of us) live in states where marijuana is legal for either recreational or medical use. Eighteen states plus the District of Columbia allow recreational pot use while 36 states allow its medical use. Let me be very clear: I am not here to politicize or moralize about whether or not marijuana should be legal either in selected states or throughout the country. This point may soon be moot because the Biden Administration, along with the Democratic Congressional leadership, have already signaled support for the decriminalization of marijuana. However, as The Warnings Doctor, it is my professional duty to be concerned about and make consumers aware of possible "hidden hazards" they may confront with the products we buy and/or use, and to advocate for warnings on or with those products so that consumers can make informed choices when they are buying or using said products. Such is the case with marijuana.

When we buy a box of cereal, we are now told all of the ingredients in the cereal, along with the amounts of those ingredients. For example, a 1/2 cup serving of Grape Nuts has 5 grams (a little more than a teaspoon) of sugar and 6 grams of protein, along with 7 grams of dietary fiber (about 1/4 of what we need, on average, in a typical day). 

When we buy a bottle of wine, not only are we told its vintage and alcohol volume, but also there is a warning label advising pregnant women, drivers and machine operators not to drink the product while pregnant, driving or working. 

And, of course, we all know that cigarettes have had a Surgeon General's warning since the 1960's. Not only are marijuana products devoid of any such warnings, at the Federal level, at least, the agency most likely to provide guidance about such warnings, the FDA (Food and Drug Administration) has their hands tied because, under Title 21, Section 811 of the US Code, marijuana is still considered a controlled substance. As long as pot is illegal at the Federal level, the FDA can't provide or enforce regulations that might actually keep us safe if we consume it.


What would those regulations, and subsequent warnings, if needed, look like? Consider that if you are stopped by a police officer for driving under the influence, the officer can administer a breathalyzer to you, and in most states, if your blood alcohol level (BAC) exceeds .08, you can be charged for driving while intoxicated. This determination is based upon science, research, regulations, etc. We know that drivers are more likely to get into accidents if their BAC exceeds .08, and we have a measuring system available (a breathalyzer) to accurately determine your level. Let's substitute weed for alcohol. You are still stopped by a police officer, perhaps because you were weaving while driving. There is no equivalent to a breathalyzer, and even if there were, what would it be measuring and what would be the maximum tolerable limits of whatever the substance(s) being measured turned out to be? The truth is that we don't have answers to these questions, thus leaving the police officer to make a totally subjective decision, a decision that could vary from officer to officer and present a nightmare for prosecutors to make their case in court.


The questions facing a puzzled police officer are the same questions we all must face as marijuana becomes legalized throughout the U.S.: How much pot does it take to get someone stoned? Does this vary by age, height, weight, ingestion of other foods or beverages, amount of sleep deprivation, ingestion and interaction with other chemicals (legal or otherwise), etc. And, if you are stoned, should there be restrictions placed on your behavior, such as driving, going to classes or work, swimming, using any machinery or engaging in other recreational activities? Putting aside the myriad of behavioral norms and rules a nanny pot state may impose (if they could), what about warnings related to the actual ingredients and amounts of those ingredients present in your pot-infused products? Why should you be required to know the amount of sugar present in your gummy bears but not have a clue as to the amount of THC (the principal psychoactive constituent of cannabis) in those same candies? Shouldn't you know the expected effect the amount of THC in your gummy bears might produce (and how long it will typically take both for these effects to be realized and to last)? If you are required to know the number of carbs in your muffins, shouldn't the amount of THC be labeled in those same muffins (or space cakes)? I find it totally ironic that the same consumers who are demanding to know the ingredients and nutritional values of their food products, not to mention if they are GMO or Gluten-free, are not storming the FDA with similar demands for all pot products.


In fairness, many states have instituted their own packaging and labeling requirements, some more restrictive than others. For example, Arizona's only labeling requirement is that the packaging be child resistant, while Alaska requires not only the labeling of the amount of THC in the product but also a series of warnings even more detailed and restrictive than alcohol warnings, highlighting marijuana's intoxicating, habit forming and addictive effects, its impairment of judgment, potential health risks and the need to avoid driving or its use if pregnant. The main concern is that there is no uniform set of rules, guidelines and warnings for all states to follow, thus leaving consumers to make their own decisions without serious scientifically-based warnings to help guide those decisions. If there are, as I believe, hidden hazards present with the consumption of pot products without proper labeling or instructions, we consumers will not be able to make informed choices about whether to buy or how to safely use such products. Happy 4/20 Day!

Artificial intelligence (AI) is rapidly reshaping the landscape of healthcare, particularly in the realm of medical diagnosis. From analyzing medical images to predicting disease risk, AI-driven tools are increasingly being integrated into clinical workflows. While the potential benefits are substantial—improved accuracy, faster diagnoses, and expanded access to care—there are also meaningful risks that warrant careful scrutiny. Understanding both sides is essential for clinicians, policymakers, and patients alike.

Lithium-ion batteries power much of modern life. From smartphones and laptops to e-bikes, power tools, and even home energy storage systems, these compact and efficient batteries are everywhere. But as their use has expanded, so too has a serious and often underestimated danger: the risk of fire. Lithium-ion battery fires are not like typical household fires. They burn hotter, spread faster, and can reignite even after appearing to be extinguished. These fires are caused by a process known as “thermal runaway,” where damage, overheating, or internal defects trigger a chain reaction inside the battery. Once this process begins, it can release flammable gases, cause explosions, and produce intense flames that are difficult to control.

1. Weakening National Drinking Water Standards  In April 2024, the EPA finalized the first federally enforceable National Primary Drinking Water Rule (NPDWR) for six PFAS, including PFOA, PFOS, PFHxS, PFNA, HFPO-DA (GenX), PFBS, and mixtures of these chemicals. These rules established maximum contaminant levels (MCLs) and required monitoring and treatment timelines for public water systems. Under Trump's EPA, this landmark public health rule is being undone :

Winter in the Northern Hemisphere brings cold weather, snow, and often severe storms. These conditions can lead to power outages that last hours or even days. When electricity is lost and temperatures plummet, many households turn to alternative heating methods or portable power generators. While these actions are understandable, they can expose families to a perilous and often invisible threat: carbon monoxide (CO) poisoning .

As Thanksgiving approaches, kitchens across the country are about to come alive with the sounds and smells of holiday cooking. While this season brings family, gratitude, and plenty of delicious food, it also comes with a serious and often overlooked risk: foodborne illness. In the U.S., Salmonella and Listeria remain two of the most dangerous and persistent causes of food poisoning—especially during the holidays, when increased food preparation, crowded refrigerators, and large holiday meals create ideal conditions for bacterial growth.Whether you’re hosting your first Thanksgiving dinner or you’re a seasoned holiday chef, brushing up on a few key food safety practices can help you keep your loved ones healthy and your celebration memorable for all the right reasons.

The race to develop autonomous vehicles (AVs) has reached a pivotal moment. Alphabet-owned Waymo, widely regarded as the frontrunner in the field, has rolled out fully driverless taxis in Phoenix, San Francisco, and Los Angeles, with plans to expand to additional cities. But as more Waymo vehicles hit public roads without human drivers, the question looms large: Are they truly safer than the people they’re replacing behind the wheel?

We are now in the middle of another football season, and the question, as asked every year: Is this sport safe enough for our high school, college, and professional athletes to play? Football has always been a violent sport of collision, glory, and growing concern. Over the last decade, research tying repetitive head impacts to chronic traumatic encephalopathy (CTE) has shaken parents, players, and the game’s governing bodies. The central realities are straightforward but sobering: repeated head impacts — both diagnosed concussions and the many “sub-concussive” blows players take — are linked to later-life brain pathology; helmets and add-ons can lower impact forces, but no helmet or cover has been shown to prevent CTE; and rule and culture changes that reduce the number and severity of head impacts are where the biggest gains lie.

On June 22, 2025, Governor Greg Abbott signed Senate Bill 25 (SB25), known as the Make Texas Healthy Again Act. Beginning January 1, 2027, Texas will require prominent on-pack warning labels whenever food sold in the state contains any of 44 specific additives—including synthetic colorants like Red 40, Yellow 5, Blue 1, titanium dioxide, bleached flour, and partially hydrogenated oils. The mandated label must declare the following:
