Alternatives to Smoking: E-Cigarettes, IQOS, Snus & More Compared
Want to quit smoking but not ready to give up nicotine? Or are you looking for a less harmful alternative to traditional cigarettes? The market now offers dozens of options — from e-cigarettes to heated tobacco to nicotine pouches. But how safe are these alternatives really? In this article we compare the most popular products based on current studies and independent research.
E-Cigarettes and Vapes as an Alternative
E-cigarettes vaporize a liquid that typically contains nicotine, propylene glycol, vegetable glycerin and flavoring agents. Unlike conventional cigarettes, no combustion takes place — so there is no tar, no carbon monoxide and none of the 7,000-plus chemicals found in cigarette smoke.
Public Health England (now OHID) concluded in a widely cited 2015 analysis that e-cigarettes are around 95 % less harmful than conventional cigarettes. This assessment has been reaffirmed in several follow-up reports. A 2024 Cochrane Review also shows that vapes are more effective for smoking cessation than traditional nicotine replacement therapies such as patches or gum.
Important to know
“Less harmful” does not mean “harmless.” Long-term studies are lacking, and aerosol exposure can vary significantly depending on the device and liquid. The German Federal Institute for Risk Assessment (BfR) warns in particular about uncontrolled flavoring agents and the gateway potential for young people.
- ✓No combustion — significantly fewer toxicants than cigarette smoke
- ✓Cochrane Review 2024: higher quit rates than nicotine patches
- ✓Long-term effects not yet fully understood
- ✓Quality and safety vary widely between products
IQOS and Heated Tobacco Products
Heated tobacco products like IQOS (Philip Morris), glo (BAT) or Ploom (JTI) heat real tobacco to around 350 °C instead of burning it at over 800 °C. This produces a nicotine-containing aerosol rather than conventional smoke. Philip Morris markets IQOS as “smoke-free” and “less harmful.”
Independent studies significantly qualify the manufacturer’s claims. A 2020 analysis published in “Internal and Emergency Medicine” shows that while IQOS aerosol contains fewer toxicants than cigarette smoke, it still releases carcinogenic substances such as formaldehyde and acetaldehyde. The BfR states clearly: “There is no safe tobacco product.”
- 1Fewer toxicants than cigarettes, but not toxicant-free
- 2Still contains real tobacco and nicotine
- 3PMI-funded studies are methodologically contested
- 4No proven advantage over e-cigarettes for quitting
Snus and Nicotine Pouches
Snus is a moist, ground tobacco placed under the upper lip — a tradition widespread in Sweden since the 18th century. Sweden today has the lowest smoking rate and the lowest tobacco-related cancer mortality in the entire EU. Proponents attribute this to the widespread use of snus as a cigarette substitute.
Modern nicotine pouches (e.g. Velo, Zyn, Nordic Spirit) no longer contain tobacco but instead use synthetic or extracted nicotine, cellulose and flavors. They are also placed under the lip and deliver nicotine through the oral mucosa.
Compared to smoking, the risk profile of snus is significantly lower: no inhalation of combustion products, no secondhand smoke, no lung cancer. However, oral tobacco use is associated with a slightly elevated risk of pancreatic cancer and oral mucosal disease. Tobacco-free nicotine pouches eliminate tobacco-specific risk, but nicotine dependence remains.
- ✓No smoke, no tar, no secondhand exposure
- ✓The Swedish model: lowest smoking rate in the EU
- ✓Tobacco-free pouches eliminate tobacco-specific risks
- ✓Nicotine dependence persists
Nicotine-Free Alternatives
If you want to leave not only cigarettes but also nicotine behind, a growing number of alternatives target the habits and rituals of smoking:
Herbal Cigarettes
Herbal cigarettes (e.g. from Nirdosh or Honeyrose) contain no tobacco or nicotine but imitate the smoking ritual. Caution: combustion still produces toxicants such as carbon monoxide and tar, so the health benefit is limited.
CBD Products
CBD liquids and CBD flower are marketed as a relaxing alternative. While CBD itself is considered non-addictive, long-term studies on inhaling CBD aerosols are lacking. Evidence for CBD as a smoking cessation aid remains thin.
Behavioral Strategies
Behavioral substitution strategies address where addiction truly begins — habits, triggers and stress moments. They replace not the chemical effect of nicotine but the automatic reach for a cigarette:
Alternatives for Stress
Stress is the most common trigger for relapse. These strategies help you get through stressful moments without nicotine:
Breathing exercises
The 4-7-8 method (inhale for 4 seconds, hold for 7 seconds, exhale for 8 seconds) has been shown to lower cortisol levels within 60 seconds.
Fidget tools and hand activities
Stress balls, fidget spinners or simply holding a pen replace the motor habit of smoking — your hand needs something to do.
Interactive games against cravings
Short, engaging mini-games redirect the prefrontal cortex and interrupt the addiction pattern. QuitBeaver offers exactly these games for the critical 3–5 minutes of a craving.

What is the healthiest alternative to smoking?
Not smoking and not consuming nicotine at all is the healthiest option. Among nicotine-containing alternatives, Public Health England rates e-cigarettes as around 95 % less harmful than conventional cigarettes. Tobacco-free nicotine pouches additionally eliminate combustion risk.
Is IQOS better than cigarettes?
IQOS releases fewer toxicants than a burning cigarette but is by no means risk-free. Independent studies show that carcinogenic substances are still produced. Compared to e-cigarettes, IQOS offers no proven advantage in harm reduction or smoking cessation.
Is snus healthier than smoking?
Yes — the risk profile of snus is significantly lower than that of cigarettes because there is no combustion. Sweden, where snus is widely used, has the lowest tobacco-related mortality rate in the EU. However, nicotine dependence persists and oral tobacco is linked to a slightly increased risk of certain cancers.
