Product substitutability in the Norwegian nicotine market 1909-2025 – and consequences for public health
This paper analyzes Norwegian nicotine market trends from 1909 to 2025, revealing a shift from combustible tobacco to snus and an overall decline in consumption, which the authors conclude will likely reduce the public health disease burden and generate future healthcare cost savings compared to the peak smoking era.

The Great Nicotine Shuffle: A 115-Year Story of Swaps and Shifts
Imagine a giant, invisible river flowing through a country. This river isn't made of water, but of nicotine—a chemical that makes people feel alert and satisfied. For over a century, this river has never really dried up; people have always found a way to get their fill. But the shape of the river has changed dramatically. Sometimes it flows fast and wide like a raging torrent of smoke, and other times it trickles quietly through a narrow channel of chew. This is the story of "product substitution." Think of it like a video game where the main character keeps changing their weapon. One day they use a sword, the next a bow, and later a laser gun. The goal (getting the points, or in this case, the nicotine) stays the same, but the tool changes based on what's available, what's cool, and what's allowed. Scientists care about this because the "weapon" matters a lot for health. Some tools are like rusty swords that cut you deeply (causing serious illness), while others are like plastic swords that are much safer. Understanding which tool people are using helps doctors and governments figure out how to keep everyone healthy.
The Long History of Norway's Nicotine River
In this paper, researchers Karl Erik Lund and Tord Finne Vedoy from the Norwegian Institute of Public Health decided to take a long, hard look at the history of nicotine in Norway. They didn't just guess; they dug through sales records and surveys from 1909 all the way to 2025. Their goal was to see two things: How much total nicotine did people consume, and what kind of products were they using?
The Flow of the River: How Much Nicotine?
If you look at the total amount of tobacco consumed per person (for anyone aged 15 and older), the story has three main chapters:
- The Stable Early Years (Until 1940): The river was calm. People consumed about 1,600 grams of tobacco per person every year. It didn't change much.
- The Big Surge (1945–1993): After World War II, the river swelled. Consumption climbed steadily, peaking around 1970 and staying high at about 2,100 grams per person until 1993. During this time, almost everything was "combustible," meaning it was burned and smoked (about 90% of the market).
- The Retreat and Stabilization (1993–2025): After 1993, the river started to shrink. By 2015, it had dropped to about 1,300 grams, and by 2025, it settled at around 1,200 grams. This is actually lower than it was before the war!
The Changing Weapons: What Did People Use?
The most exciting part of the story is how the "weapons" swapped places. The authors describe five distinct phases where one product took the lead, only to be replaced by another:
- The Chewing Era (Early 1900s): At the start, plug tobacco (a block of chew) was the king. It was so popular that people needed "spittoons" (cups to spit into) in public places. But as germ theory spread and people realized spitting was gross and unhealthy, this product lost its cool factor.
- The Pipe Era (Late 1920s–1950s): Pipe tobacco took over. It was seen as a slow, thoughtful, and "manly" hobby. It involved rituals like packing the tobacco and cleaning the pipe. It didn't have the same "spitting" stigma, so it ruled for a while.
- The Roll-Your-Own Era (1960s–1990s): Then, hand-rolled cigarettes became the favorite, especially among working-class people and in rural areas. They were cheaper because of tax breaks. Rolling your own was a skill and a ritual, but as life got faster and busier, the slow process of rolling didn't fit anymore. When the tax breaks ended in the mid-1990s, this product crashed.
- The Cigarette Era (2000s): Manufactured cigarettes (the pre-made kind you buy in packs) finally became the dominant product in the early 2000s. They were fast, easy, and marketed globally.
- The Snus Era (2004–2025): Finally, the tide turned toward snus (a moist tobacco product placed under the lip). A ban on smoking indoors in 2004 made smoking less convenient, while snus could be used anywhere without bothering others. Plus, it was cheaper. By 2025, snus made up 55% of the total tobacco market in Norway.
The "Substitution" Theory: Did It Work?
The paper tests a famous idea from a researcher named Michael Anthony Hamilton Russell. He argued that people are addicted to nicotine, not the specific product. So, if you ban one thing, they will just swap it for another.
- What the paper found: The theory is partially true. The "niche" products (chewing, pipes, roll-your-own) did swap places with each other and then faded away. However, the theory that the total amount of nicotine stays exactly the same is not true. The total amount went up and down significantly.
- The Twist: While the total volume changed, the type of product changed in a way that matters for health. The market moved from mostly burning tobacco (cigarettes) to mostly non-burning tobacco (snus).
Why This Matters for Health
The authors explain that burning tobacco creates dangerous stuff like tar and carbon monoxide, which cause diseases like lung cancer and heart problems.
- The Old Days (1945–1993): The market was dominated by burning products. This was the "danger zone" for public health.
- The New Days (Post-1993): As people switched to snus, they stopped burning tobacco. The paper notes that while snus isn't perfectly harmless (it can still affect blood pressure and pregnancy), it is much less harmful than smoking. It doesn't seem to cause lung cancer or the breathing diseases that smoking does.
- The Future: The paper suggests that this shift from smoking to snus, combined with the overall drop in how much tobacco people use, will likely lead to fewer sick people and lower healthcare costs in the future.
A Few Caveats
The authors are careful to say they can't see exactly why individual people switched (was it price? health fears? peer pressure?). They also note that their data doesn't include e-cigarettes (vaping) yet, because there's no easy way to measure how much nicotine is in a bottle of e-liquid compared to a gram of tobacco. So, the real amount of nicotine people are using today might be slightly higher than the charts show.
The Bottom Line
Norway's nicotine market has been a long game of musical chairs. The chairs (products) changed from chewing to pipes to rolls to cigarettes to snus. While the total number of players (total consumption) went up and down, the most important change is that the players are now using safer "chairs." The shift away from burning tobacco suggests a brighter, healthier future for the population.
