We give a structural theorem for Q-factorial toric varieties covered by lines in P-N, and compute their dual defect. This yields a characterization of defective Q-factorial toric varieties in P-N. The combinatorial description of such varieties is used to characterize some finite sets of monomials with discriminant equal to one.
