  We study the ejection of winds from thin accretion discs around stellar mass
black holes and the time evolution of these winds in presence of radiation
field generated by the accretion disc. Winds are produced by radiation, thermal
pressure and the centrifugal force of the disc. The winds are found to be
mildly relativistic, with speeds reaching up to terminal speeds $0.1$ for
accretion rate $4$ in Eddington units. We show that the ejected matter gets its
rotation by transporting angular momentum from the disc to the wind. We also
show that the radiation drag affects the accretion disc winds in a very
significant manner. Not only that the terminal speeds are reduced by an order
of magnitude due to radiation drag, but we also show that the non-linear effect
of radiation drag, can mitigate the formation of the winds from the matter
ejected by the accretion disc. As radiation drag reduces the velocity of the
wind, the mass outflow rate is reduced in its presence as well.
