Are they whole spices (cinnamon stick, whole cloves...) or just powdered? Are you adding them at the beginning of the boil or at knockout? I don't think the spices will be detrimental to fermentation, but you will probably lose some of the aroma through your airlock or blow off tube.
I usually add a conservative amount of ground spice at 5 min left in the boil, so that the spice gets mixed into the wort. I'll then adjust the the spicing post fermentation. I do this in the keg, but used to do this in the bottling bucket in my pre-kegerator days.
