Recently, governments in developed countries have been trying to reduce smoking. In Sweden, perhaps due to these efforts or because of the cold climate (because it's impossible to smoke outside in winter at -30 Celsius), it is difficult to find a smoker. Instead, many Swedes use snus. The most popular type is "portion snus" (moist tobacco in a small pouch held under the lip).
Both of them are harmful in different ways but I wonder, which one is more harmful? Is there any research about this?
The snus is illegal in European Union, except Norway and Sweden, which suggests it may be more harmful. In the EU countries, cigarettes are legal but they create smoke that affects the lungs and cause lung cancer.
All the affects of snus are still not clear, but causes mouth, tongue and pancreatic cancer. It also allows nicotine and other chemicals (e.g. salt crystals, E1520, E500) to flow directly to your salivary & your circulatory system.
Snus is consumed for a period of around an hour, but a cigarette lasts at most 5 minutes.
