An effective-mass Hamiltonian is derived for carbon nanotubes in the presence of a weak spin-orbit interaction. The spin-orbit interaction gives rise to terms corresponding to a kind of a spin-Zeeman energy due to magnetic fields in the circumference and axis direction. As a result spin scattering is induced even by spin-independent scatterers.
