We present a microscopic approach to study electromagnetic wave propagation in media with broken mirror symmetry. We introduce and calculate the transport mean free path <i>l</i><sub>C</sub>* associated with the residual polarization of diffuse light in chiral systems. In chiral media subject to an external magnetic field <b>B</b>, all symmetry requirements exist to create a macroscopic “super” light current in the direction of <b>B</b> that persists even in the absence of a spatial photon density gradient. However, we show that such a current is identically zero in our model. We finally show the existence of a linear magnetotransmission in magnetochiral media.
