I was working the final in a south flow. Aircraft X reported a near miss with a drone passing 100 feet above him on the downwind into the airport. Aircraft Y was on a downwind and slightly behind and to the east. In dealing with the supervisor and trying to spread the word about the drone inside the class B airspace in a place that mulitple secotrs can use through pre-arranged coordination. I thought that I had descended Aircraft X to 3000 feet; I turned Aircraft Y westbound to base leg behind Aircraft X. I in fact did not descend AircraFT X; I left him at 4000 feet. When I noticed what had happened I descended and turned both aircraft away from each other. Both landed without incident. Make flying a drone in controlled airspace stricter penalties. Had the drone not been there my workload would not have gone through the roof trying to keep aircraft away from the area.
D10 TRACON Controller reported an aircraft they were vectoring reported a near miss with a drone. The drone distraction and added coordination were cited as contributing to another airborne conflict between two manned aircraft.
