• We present a comprehensive theory of the electrostatic drift instabilities of acollisionless plasma in a toroidal device. The effects of inhomogeneities (density,electron and ion temperature gradients), plasma current, radial electric field,magnetic shear arnd toroidal curvature drift are simultaneously examined ; NVC derive= the general but simple criteria for the drift stability. The instabilities are found tobe excited owing to the plasma current, ion temperature gradient, curvatt?re of toncross-field flow and toroidal effects, although the m'tgnetic shear has a pt'ominentstabilizing power. Drift waves are expected to be almost always un:stable intokamak plasrnas.
