Abstract
We demonstrate that the long distance contribution to B-+/- --> rho(+/ -)gamma may have a large effect on the decay rate and through it on th e CP violating partial rate asymmetry. The change in the asymmetry can be between a factor of 0.4 and 1.4 with respect to the effect of the short distance contribution alone, depending on the values of the CKM parameters rho and eta.
