Abstract: An application of quantum causal analysis to asymmetric entangled states under decoherence is considered. Two models of decoherence: dissipation and depolarization are studied. For the both models the strength and the direction of induced causality has been computed. It turns out that the decoherence acting along original causality destroys entanglement to a lesser degree than it acting against this causality.
