Tobacco Harm Reduction (THR) is a policy and process by which smokers who are unable or unwilling to quit smoking are enabled and encouraged to switch to a lower risk tobacco/nicotine product to reduce their future risk of potentially fatal cancer, heart and lung disease.

In this policy statement, R Street lays out its view that current U.S. tobacco control policy has the practical effect of reinforcing the cigarette as the primary means of nicotine delivery by protecting cigarettes against competition by far less hazardous non-prescription alternatives.
