The graphene inspired lattices recently proposed by Creutz and Borici have sparked interest in the use of non-orthogonal lattices in lattice QCD. These lattices have the desired chiral symmetry and have the minimal doubling required by the Nielsen-Ninomiya no-go theorem. However, due to the lack of discrete symmetries, radiative corrections in the gauged lattice theory will lead to the generation of unwanted relevant and marginal operators. In this talk, the viability of these graphene inspired lattices, as well as other non-orthogonal lattices, will be discussed.
