Hand-rolled cigarettes more carcinogenic: study - Reuters / Yahoo

Smokers of hand-rolled cigarettes tend to consume less tobacco, but face a greater risk of developing lung cancer than those who smoke manufactured cigarettes, a study on Norwegian lung cancer patients has found.

While smokers of hand-rolled cigarettes "consumed (fewer) cigarettes, and statistically had fewer years of smoking, hand-rolled cigarettes were more carcinogenic, resulting in a higher incidence of lung cancer development," the study by Heidi Rolke, of Norway's Sorlandet Hospital, said.
