In this note we prove that the q-ample cone of a simplicial projective toric
variety in characteristic zero is always the interior of a finite union of
polyhedral cones. We use this result to prove a characterisation of the q-ample
cone of a simplicial projective toric variety in terms of the vanishing of
K\"uronya's asymptotic cohomological functions.
