Rapidly decaying systems were studied using the stochastic limit approximation method. A Bloch equation having two independent time scales was derived from the spin-boson model. At high temperatures, minimal dissipative dynamics can be obtained using this method. The derived master equation confirmed the validity of the method. For practical calculations the Stochastic limit approximation was found to be useful.
