Are the simulations accurate?

The simulations used on this website are based on years of research into tobacco smoke exposure in homes, cars, and other locations. They have been tested in real locations and are expected to give realistic predictions of actual exposures for real people. However, the simulations should not be viewed as giving exact data on any given situation, but only an approximate characterizaton of likely exposures. They are intended to be useful in providing general knowledge and understanding regarding potential exposures in common locations and for common circumstances. The operators of this website do not guarantee the use of the simulation results for any expressed or implied purpose.
