Concentration-effect curves for inhaled toluene vapor, i.p. injected toluene and a combination of 100 mg/kg i.p. toluene + inhaled toluene vapor in mice trained to discriminate 10 min of exposure to 6000 ppm inhaled toluene vapor from air (n=7). Filled squares represent mean (± SEM) toluene-lever selection resulting from inhaled toluene exposure. Open circles represent mean (± SEM) toluene-lever selection resulting from i.p. injected toluene. Open triangles represent mean (± SEM) toluene-lever selection resulting from combining 100 mg/kg i.p. injected toluene with inhaled toluene. Points above Air, Air+veh and Tol represent toluene lever selection on air (open square), air + i.p. toluene vehicle and 6000 ppm inhaled toluene (filled square) exposure control sessions, respectively.
