Researchers in Sweden studied 4,222 men from Västmanland. The participants were either 40 or 50 years old when the study began in the 1990s.
None of the men smoked or had previously smoked. This allowed researchers to better determine whether snus itself had an impact on health.
Differences appeared after ten years
The men were followed for up to 32 years. Researchers compared those who used snus with those who did not.
According to Aftonbladet, as cited by News 55, the differences only began to emerge after around ten years.

The study did not measure how much snus the participants used. As a result, researchers cannot say exactly how much use is required before the risk increases.
Risk increased
Snus users faced a higher risk of certain cardiovascular diseases.
The risk of high blood pressure was 64 percent higher, while the risk of heart failure was 75 percent higher, Aftonbladet reported, citing the study published in the Scandinavian Journal of Public Health.
The researchers did not find a clear increase in the risk of premature death. They also emphasized that snus is less harmful than smoking, but it is not without health risks.
