The increased resistivity resulting from the lower-hybrid-drift (LHD) instability is shown to increase the Pease--Braginskii current {ital I}{sub PB} in a Z pinch and to make radiative collapse harder to achieve; {ital I}{sub PB} becomes a function of both the line density and the pinch radius and a minimum {ital dI}/{ital dt} is necessary to induce collapse. The effect of the LHD instability is greatest in a hydrogen pinch, and decreases with increasing atomic number.
