Every smoker knows smoking causes cancer. But ask them about their personal risk, and the answer changes. The gap between general knowledge and personal belief is one of psychology's most lethal phenomena.
From the UK to France to Australia, nations are racing to ban disposable e-cigarettes. But banning a product doesn't make it disappear—it changes who sells it, who buys it, and what's in it.
Vape advocates love comparing nicotine to caffeine. Tobacco controllers call it dangerous misinformation. Both have a point. Here's what the analogy gets right, what it gets wrong, and why it matters.

What actually happens inside the body—hour by hour, day by day, year by year—after a smoker quits? The repair process is one of the most remarkable in human biology, and understanding it can be the difference between relapse and recovery.
When the U.S. banned shipping vaping products through the mail in 2021, it was framed as a youth protection measure. Two years later, the results are mixed—and the law of unintended consequences is working overtime.
Early in the pandemic, a paradoxical finding emerged: smokers seemed underrepresented in COVID-19 hospitalizations. The ensuing scientific scramble revealed both the dangers of premature conclusions and the complexity of nicotine's biology.

A growing number of governments are taxing e-cigarettes at rates comparable to combustible cigarettes. The logic is revenue and parity. The effect is to make the safer product less affordable relative to the deadly one.
The world's largest tobacco company and the world's top health authority are locked in a propaganda war over the future of nicotine. Both claim to follow the science. Both accuse the other of distortion. Who actually controls the narrative?

People with mental health conditions smoke at twice the rate of the general population and die 10–20 years earlier, largely from smoking-related diseases. Addressing this gap is the most urgent—and most neglected—priority in tobacco control.

Menthol and mint are the most popular e-liquid flavors among both adults and teens. Ban them, and you risk driving adult vapers back to smoking. Keep them, and you preserve the youth-appealing flavor that's hardest to justify.
TikTok, Instagram, and YouTube didn't create youth vaping—but they've made it visible, viral, and normalized in ways that regulators are only beginning to understand. The algorithm is the new advertising.
NRT—patches, gum, lozenges—is safe, effective, and available over the counter. So why do fewer than 10% of quit attempts involve it? The answer reveals uncomfortable truths about access, education, and addiction stigma.
Cannabis vape cartridges now dominate legal marijuana markets—and the playbook looks familiar. From flavor names to Instagram marketing, the cannabis industry is replicating nicotine vaping's trajectory, including its mistakes.
As Western smoking rates plummet, the tobacco industry is betting its future on Africa—a continent with young populations, weak regulation, and rising incomes. The battle for Africa's lungs is just beginning.
Twin studies, genome-wide association scans, and neuroimaging genetics are revealing that smoking behavior is substantially heritable. Understanding the genetic architecture of nicotine addiction could transform cessation—and raise ethical questions.

Flavors help adult smokers quit. Flavors attract teenagers to start. Both statements are true and supported by evidence. The policy challenge is that they describe the same products, and we can't ban one without affecting the other.
Raising tobacco taxes is the single most effective intervention to reduce smoking—more effective than advertising bans, health warnings, or cessation programs. Yet most countries keep taxes far below the WHO's recommended levels. Why?
Millions of people both smoke and vape. Public health orthodoxy treats dual use as a failure—but emerging evidence suggests it might be a transitional state leading to eventual cessation. The data tells a more complex story.
IQOS and similar 'heat-not-burn' devices sit in an awkward middle ground—too much like smoking for vape advocates, too much like quitting for the tobacco industry. But tens of millions of people are using them. What's actually going on?

Hospitals refuse to hire smokers. Insurance companies charge them more. Employers test for cotinine and deny coverage to those who test positive. Is nicotine screening a public health tool or a form of discrimination?
The tobacco industry should be politically radioactive. Its products kill half their long-term users. Yet it continues to block, delay, and weaken tobacco control legislation worldwide. How does it keep winning?
Independent vape shops are where most adult vapers get their products and advice—but they're also where many underage users obtain devices. Can the industry regulate itself, or is the corner vape shop an endangered species?

Sweden has the lowest smoking rate in Europe, the lowest tobacco-related cancer mortality, and a centuries-old tradition of oral tobacco called snus. Why hasn't the rest of the world followed the evidence?
Smoking rates in prisons are up to four times the general population rate. Most prisons have banned smoking—but bans don't treat addiction. What does justice-appropriate cessation look like?
