Honestly, if you looked at a crowded street in 1965, almost half the adults there would be lighting up. It was the norm. Fast forward to today, and the vibe has shifted so much it’s almost unrecognizable. But if you’re asking for a single, clean number for the percentage of people who smoke, you’re going to be disappointed. The data is messy, regional, and currently being turned upside down by the rise of "alternative" products.
According to the latest World Health Organization (WHO) report released in late 2025, about 1 in 5 adults worldwide are still using tobacco. That’s roughly 20% of the global grown-up population. In absolute numbers, we're talking about 1.2 billion people. It sounds like a lot—and it is—but the trend is actually downward. Back in 2000, that number was closer to 1.38 billion. We’re smoking less, but the "tobacco epidemic," as the experts like to call it, is far from over.
The Global Split: Who is Actually Lighting Up?
The "20% global average" is a bit of a lie because it hides some wild geographic swings. If you’re in Africa, you’ll see some of the lowest smoking rates on the planet—around 9.5% in 2024. But move over to Europe, and the story flips completely. Europe is currently the highest-prevalence region globally, with about 24.1% of adults using tobacco.
Then there's the gender gap. It is massive. Globally, men are far more likely to smoke than women. We're looking at roughly 32.5% of men versus just 6.6% of women. In places like South-East Asia, the disparity is even crazier. In Indonesia, for example, 2025 data shows over 70% of men smoke, while the female rate is a tiny fraction of that.
What’s Happening in the United States?
In the U.S., the CDC reported some pretty historic news in March 2025. Adult cigarette smoking hit a 60-year low. We are down to about 11.6% of adults who smoke traditional cigarettes. If you compare that to the 42.4% rate in 1965, it’s a massive public health win.

But there is a catch. A big one.
While cigarette use fell, e-cigarette use (vaping) skyrocketed. Between 2017 and 2023, the U.S. saw a decrease of about 6.8 million cigarette smokers, but that was almost perfectly offset by a 7.2 million increase in exclusive e-cigarette users. Essentially, people aren't necessarily quitting nicotine; they’re just changing the delivery mechanism.
The Age Factor
The "who" matters as much as the "how many."
- Young Adults (18–24): Only about 1.2% are smoking traditional cigarettes now. That’s a huge drop. However, over 10% of this group are regular vapers.
- Older Adults (65+): This is the only group where cigarette smoking actually saw a slight bump in recent years, likely due to a "cohort effect" of people who have smoked for decades.
The Vaping "Takeover"
We can’t talk about the percentage of people who smoke without mentioning the Great Britain milestone. In January 2026, the Office for National Statistics confirmed that for the first time, the number of vapers in Great Britain (5.4 million) officially overtook the number of cigarette smokers (4.9 million).

This is a massive cultural shift. In the UK, the government has been much more open to using vapes as a cessation tool compared to the U.S. or Australia. This "substitution" effect is the main reason why the traditional smoking percentage looks like it’s dying out, even if nicotine addiction is staying steady or even rising in some pockets.
Does "Occasional" Smoking Count?
A lot of people think if they only have a couple of cigarettes when they’re out with friends, they aren't "smokers." The data people—researchers like those at the American Heart Association—don't care about your labels.
Recent 2025 studies followed over 320,000 adults and found that even "light smokers" (those having 2 to 5 cigarettes a day) have a 60% increased risk of death from any cause compared to non-smokers. There’s really no safe threshold. If you’re in that "social smoker" category, you’re still part of the percentage that health insurance companies and doctors are worried about.
Why Some Countries Just Won't Quit
You might wonder why, with all the warnings, the numbers don't just hit zero. It basically comes down to "MPOWER." That’s a set of six strategies the WHO pushes:

- Monitoring use.
- Protecting people from smoke (bans).
- Offering help to quit.
- Warning about dangers.
- Enforcing advertising bans.
- Raising taxes.
Countries that do all six, like New Zealand or Brazil, see their smoking percentages crater. Countries that lag on taxes or advertising bans (like many in the Eastern Mediterranean) see their numbers stay flat or even rise. Interestingly, as of 2025, about 134 countries have still failed to make cigarettes "less affordable" through taxes, which is the single most effective way to drop that percentage.
Practical Takeaways for 2026
If you're looking at these numbers and thinking about your own habits or those of someone you know, here’s the ground reality:
- The "Switch" isn't a "Quit": Moving from cigarettes to vapes might reduce some carcinogen exposure, but 2026 data shows that "dual-use" (doing both) is incredibly common and doesn't actually lower your health risks significantly.
- Taxes work: If you're looking to quit, moving to a high-tax state or country is statistically one of the best "nudges" you can give yourself.
- Cessation services are underused: Only about a third of the world has access to cost-covered help to quit. If you're in a country like the U.S. or UK, you actually have access to resources that most of the world doesn't.
The percentage of people who smoke is falling, but it’s being replaced by a more complex landscape of nicotine pouches, heated tobacco, and high-strength vapes. We are moving away from the "smoke" but not necessarily away from the "addiction."
To make a real dent in your own health stats, the goal shouldn't just be to get out of the "smoker" column, but to get out of the "nicotine-dependent" column entirely. Start by checking your local health department for "quitline" services, which in many regions now offer free patches or coaching specifically tailored to the newer high-nicotine products that have flooded the market.
