A study, led by researchers from the University of Illinois at Urbana-Champaign, was conducted on a large population-based control regarding possible connections between marijuana use and OSCC, a type of oral cancer. Researchers studied lifestyle habits of 407 oral-cancer cases and 615 healthy control subjects including males and females ranging from age 18 to 65.  They concluded that “We did not see an increase in risk for oral cancer in people who had ever smoked marijuana after controlling for other risk factors.”  The researchers stated that a potential problem with this study was that the members of the control group were strictly blood donors, who do not typically represent the population’s habits at large.
