Swedish snus

Fine ground tobacco leaves

predominantly from air-cured dark tobacco

Manufactured by a pasteurizing-like heating process (without any fermentation so as used in most manufacturing procedures for American snuff)

∎ TSNA content: < 5 mg/kg

∎ BaP content: < 10 g/kg

(TSNA content of American snuff: 16-130 mg/kg)

“In Sweden, the availability and use by men

of an oral tobacco product called snus, one of

the less hazardous smokeless tobacco

products, is widely recognised to have

contributed to the low prevalence of smoking

in Swedish men and consequent low rates of

lung cancer.”

Summary• E-cigarette smoking may be substantially less

harmful to health than cigarette smoking, but more research is needed before definitve conclusions can be drawn.

• Water pipe smoking appears to be even more harmful to health than cigarette smoking.

• Snus use appears to- decrease juvenile onset of smoking- help smokers to quit all tobacco use- offer a substantially less harmful alternativefor those who are unable or unwilling to quitcompletely.
