A very recent report from the Norwegian Institute of Public Health claims that snus can lead to an increased risk of "non-affective psychosis" and an increased response to cocaine.
Snus is becoming increasingly popular while smoking is on the way. In the youngest age group, one in four men is a sniff, and 15 per cent of women.
An increasing number of people also start using snuff instead of using it as a smoking cessation product. In the period 2016-2018, 33 per cent of men and 40 per cent of women did not smoke before starting snuff.

To update the knowledge about the possible health risks of snuff, the Ministry of Health has ordered a knowledge update two years ago. On Wednesday, the Institute of Public Health published its review.
Although most of it is known before, with an increased risk of certain types of cancer and heart disease, there are also some points that cause experts to scratch their heads.
Under the chapter "Mental Illness," the FHI argues, "It is possible that the use of Swedish snuff increases the risk of non-affective psychosis." The institute states that it is uncertain whether it can lead to an increased risk of schizophrenia.
FHI writes "Swedish snuff" is meant to distinguish it from products such as oblique tobacco and chewing tobacco.
Snuff can also lead to increased response for cocaine later in life, FHI believes in the report.
"Animal studies have shown that nicotine may increase the likelihood of using other drugs such as cocaine (the gateway hypothesis), and animal studies show that nicotine exposure in young animals results in increased response to cocaine later in life"

Cancer and diabetes
According to the report, researchers at the Institute of Public Health can conclude that it is likely to increase the risk of the following health e-problems using snus:
- Esophageal and pancreatic cancer
- High blood pressure among men
- Diabetes type 2 and metabolic syndrome
- Premature birth in women
- Mortality after heart attack and stroke [1965someproblemsconcludeFHIis"possible"snuffincreasestheriskof:

But it's not just bad news for snus health. Those who are looking to find some positive health news about snuff can take comfort in the fact that a study showed that using snuff reduced the risk of getting Parkinson's disease.
Senior researcher Karl Erik Lund at the Institute of Public Health believes that snus is far less dangerous than smoking, and is critical of the report.
– It fails to compare risk from snuff use with risk from smoking. The majority of snus users still come from smokers. For smokers and former smokers, it will be useful to gain knowledge about risk differences between the products, he says to the research site research.no.
Lund points out that one possible reason why the injury differences are not reduced may be that the Ministry of Health did not want the injury reduction perspective to be included in the report.
