Snus users ‘absorb more carcinogens’

People who use Swedish oral tobacco, snus, absorb higher levels of some cancer-causing substances than smokers, according to a new study. Snus users also had higher levels of nicotine in their bodies than smokers, the study by researchers at the University of Minnesota said.

Snus users 'absorb more carcinogens'

The study of 420 smokers and 182 snus-users was published in the journal Cancer Epidemiology, Biomarkers and Prevention.

The principal author, Professor Stephen S Hecht, said that oral consumption of tobacco appears to me a more effective way of delivering cancer-causing substances to the body than smoking. However, he added that cigarette smoke contains a higher number of more dangerous carcinogenic substances, Svenska Dagbladet reports.

A Swedish study earlier this year showed that snus-users were twice as likely as non-users to develop pancreatic cancer, although the risk for smokers was even greater for tobacco users.
