Narrative:

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.
