  In this paper we study the so called "warp drive" spacetimes within the
$U_{4}$ Riemann-Cartan manifolds of Einstein-Cartan theory. Specifically, the
role that spin may play with respect to energy condition violation is
considered. It turns out that with the addition of spin, the torsion terms in
Einstein-Cartan gravity do allow for energy condition respecting warp drives.
Limits are derived which minimize the amount of spin required in order to have
a weak/null-energy condition respecting system. This is done both for the
traditional Alcubierre warp drive as well as for the modified warp drive of Van
Den Broeck which minimizes the amount of matter required for the drive. The
ship itself is in a region of effectively vacuum and hence the torsion, which
in Einstein-Cartan theory is localized in matter, does not affect the geodesic
nature of the ship's trajectory. We also comment on the amount of spin and
matter required in order for these conditions to hold.
