What happened to trusting medical experts?

d06a5ec1-c999-4558-8853-0d547f87d2f6

In all aspects of our lives, we rely on experts, from home repairs to weather forecasting to food safety, and just about everything else that’s part of modern society. There’s just no way to know everything about everything. Yet when it comes to medicine, people seem to be taking their health in their hands in ways they’d never consider if, say, their car brakes needed repairs and they weren’t auto mechanics.

What if your brakes were shot?

Suppose a well-recommended car mechanic tells you your brakes need repair. Hopefully, they explain why this is necessary and review the pros and cons of your options, including no repairs. You certainly could get additional opinions and estimates. But to make a decision, you’d have to accept that a mechanic has specialized knowledge and that their advice is sound. Quite likely, you’d get the brakes fixed rather than risk injury.

Would you berate the mechanic personally because they told you something you didn’t want to hear about your beloved car? Let's hope not. And unless you knew a lot about cars, you probably wouldn’t tinker with the brakes yourself, or take the advice of a neighbor to spray the tires with vegetable oil because a friend of his cousin said it worked for his car. And you wouldn’t take your car to a veterinarian — it just wouldn’t make sense, right?

Yet hundreds of thousands of people in the US are rejecting advice on getting a COVID vaccine from well-respected health authorities like the National Institutes of Health (NIH), Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA). Healthcare providers have somehow become the target of taunts, hostility, and even death threats for encouraging people to protect themselves and others.

Fear of the proven and an embrace of the unproven

What’s driving this? It seems to be some combination of distrust ("these so-called experts don’t know what they’re talking about"; "they rushed the vaccines just to help the drug companies") and unfounded suspicion ("they’re trying to control us, experiment on us, inject microchips in us"). Some people see recommendations regarding COVID-19 as attacks on American values ("mask and vaccine mandates infringe on my personal freedom").

At the same time, many who dismiss the advice of true experts are embracing unproven and potentially dangerous remedies, such as ivermectin pills and betadine gargles.

How did we get here?

Some reasons we’ve seen erosion in trust placed in public health experts are

  • Politics. COVID-19 quickly became a political issue in the US. For example, trust in the CDC varies markedly by political affiliation, with Democrats giving much higher marks to the CDC, FDA, and NIH than Republicans.
  • Social media. Misinformation spread through social media is rampant, and much of it has been linked to a small number of people.
  • "Pseudo-experts." Even impressive credentials don’t automatically qualify everyone to be experts in a pandemic disease. Recent examples include radiologists, cardiologists, and chiropractors who have made headlines with their controversial views.
  • Personal gain. Some have profited financially, politically, or otherwise by deliberately spreading health disinformation and denouncing expert advice.

Confusing changes in message

Public health messaging about protecting ourselves from COVID-19 also affects trust. For example, recommendations around wearing masks were inconsistent early on, and have continued to change since then.

While some confusing, seemingly contradictory messages were true missteps, most are simply changes in recommendations based on a change in circumstances, such as spiking virus cases or a more easily spread variant causing severe illness, hospitalizations, and deaths.

Particularly in the early months, no one had all the answers. But as we have accumulated information from research and real-world experience, changes in recommendations should not only be expected but embraced. It’s usually a reflection of the close attention experts are paying to changing circumstances.

Doing your own research?

A wait-and-see policy can be risky — and not just when it comes to fixing your car brakes. The virus that causes COVID-19 was only discovered 18 months ago, and vaccines have been in use for less than a year. Yet already we have an enormous amount of data from research and real-world experience from many millions of people.

So, when someone says they want to "wait and see" or "do their own research" rather than accept the advice of their own doctors or public health experts, what exactly does that mean? Are they waiting to see if something bad will happen to those who were vaccinated? How long is long enough?

Unless you’re a cutting-edge virologist, immunologist, epidemiologist, or public health expert, doing your own research isn’t likely to provide more reliable data than studies published in peer-reviewed medical journals that guide the CDC and FDA. Of course, most people "doing their own research" are relying on others who are also not doing actual research, yet they discount the findings and recommendations of true experts.

It’s important to ask questions. But pose them to your doctor. Rely less on people who tell you what you want to hear, and more on those who trained in science and whose careers have been devoted to improving health.

Can vaping help you quit smoking?

Lately it seems like everywhere I look, someone is vaping as they walk by, stand outside a store, or roll up in the car next to me at a stoplight. It’s not surprising: e-cigarette use, or vaping, has become remarkably popular in recent years. About 6% of adults in the US now report vaping. That’s about 15 million people, double the number from just three years ago. Of course, regular cigarettes are known to cause cancer and a host of other health problems.

While considered less harmful than smoking tobacco, vaping isn’t risk-free. We know some, but not all, of its risks. We also know vaping is increasingly popular among teens and young adults, and this makes the recent FDA announcement authorizing sales of three additional vaping products surprising.

A surprise announcement from the FDA

In its announcement, the FDA authorized the R. J. Reynolds Vapor Company to market and sell its Vuse Solo device with tobacco-flavored vaping liquid to adults.

The FDA denied marketing authorization for 10 flavored products made by the same company. It also reports having denied more than a million flavored vaping products from other companies.

By the way, the agency emphasizes it is not actually approving these vaping products, or declaring them safe. The announcement states that marketing authorization will be reversed if

  • the company directs advertising to younger audiences
  • there is evidence of “significant” new use by teens or by people who did not previously smoke cigarettes
  • R. J. Reynolds does not comply with extensive monitoring requirements.

Why did the FDA take this action?

The decision was reportedly based on data from the company — unfortunately not provided in the press release — demonstrating these products would benefit individuals and public health. How? By helping smokers quit.

Some studies have suggested that e-cigarette use can be modestly helpful for smokers trying to quit. For example, an analysis of 61 studies found that e-cigarette use was more effective than other approaches to quitting smoking. The study authors estimated that out of every 100 people who tried to quit smoking by vaping, nine to 14 might be successful. When only using other methods, such as nicotine patches or behavioral counselling, only four to seven smokers out of 100 might quit. A separate study suggests vaping may help smokers who aren’t able to quit reduce the number of cigarettes smoked per day — at least for six months, the duration of the study.

Does vaping harm health less than smoking cigarettes?

Despite claims that vaping is less harmful than smoking cigarettes and that it might help smokers quit, concern about its risks is well deserved.

  • Nicotine addiction. Whether in cigarettes or vapes, nicotine is highly addictive. And the amount of nicotine in many vaping products is much higher than in regular cigarettes. Side effects include reduced appetite, increased heart rate and blood pressure, nausea, and diarrhea.
  • Harm to lungs and heart. Vapors from e-cigarettes may contain cancer-causing toxins, metals, and lung irritants. Vaping raises risk for lung diseases, such as emphysema, asthma, chronic bronchitis, and chronic obstructive pulmonary disease. It’s also linked to an increased risk of heart attacks. Even secondhand exposure to e-cigarette vapors may trigger asthma.
  • Severe, potentially fatal lung injury. In 2019, doctors began seeing people who had recently vaped and developed shortness of breath, cough, fever, and extensive lung damage. Dubbed EVALI (e-cigarette or vaping product use-associated lung injury), more than 2,800 cases and 68 deaths were reported. The condition has been linked to vapors containing THC and a form of vitamin E (called vitamin E acetate) used as a thickening agent when vaping THC. Cases have fallen markedly since 2020. Possibly because of falling case numbers, the FDA announcement of new vaping products didn’t even mention EVALI, which seems odd. If you do vape, see these recommendations to reduce the risk of EVALI.
  • Health risks during pregnancy. Nicotine can damage a baby’s developing brain and lungs; some flavorings may be harmful as well. As a result, experts recommend that people who are pregnant not vape.

For teens and children, vaping has additional risks

An alarming number of middle-school and high-school age kids report vaping, despite the nationwide prohibition against selling e-cigarette products to anyone under age 18 (21 in some states). Its popularity is partly related to the marketing of flavors known to appeal to minors, such as bubblegum and berry-flavored products. According to one national survey, approximately 85% of teen vaping involved non-tobacco flavored products.

It’s important to know that

  • nicotine negatively affects the developing brain
  • the high exposure to nicotine and other toxic chemicals through vaping may be particularly harmful to kids because of their smaller body size
  • the addictive potential of nicotine may mean that kids who vape are more likely to become cigarette smokers.

The bottom line

For nonsmokers and teens, there is no controversy: don’t start smoking and don’t vape.

If you’re an adult smoker trying to quit, be aware that the balance of risks and benefits and the long-term health consequences of vaping are uncertain. We need more solid research to help people make decisions. Meanwhile, the FDA has come down on the side of a limited authorization to help adult smokers quit. We’ll know only in retrospect if that was the right move.
