Research in the late 2000s alluded to the potential problem of this form of pollution but ongoing public and academic scrutiny has not yet resolved the issue. Dubowski's work does provide a chemical basis for a possible risk but does not prove that the risk is substantial or otherwise. However, what is certain is that firsthand smoke is directly hazardous to the health of the smoker and recent evidence suggests that it could cause genetic damage almost the instant tobacco smoke is inhaled.
