The observation of a gamma-ray line would be a strong hint towards the detection of dark matter (DM). We investigate the possibility that such a line is produced through a slow DM decay. This can be studied in a systematic and model-independent way through the derivation of the corresponding effective theory. We wrote down this effective theory for both neutral and millicharged DM candidates. The use of the effective theory allows for a multi-channel analysis, and in particular constraints on the potential intensity of a line arise from the production of cosmic rays associated to the line.
