Public awareness about tobacco -related oral cancer is low at present, and new approaches to this problem should include education in the schools on oral cancer, formulation of legislative action to ban the sale of tobacco near schools and colleges, and imposition of societal "barriers" that would make the nonchewing of tobacco socially more acceptable than chewing it.	success	detect	detect	make relation
