I have seen very cheap coaster brake hubs (on kids bikes mainly) that have noticeable drag. But when I have ridden good coaster brake hubs, like Shimano Nexus, I do not notice any additional drag. It is possible that there is a tiny amount of extra drag (<5w) that might make a bit of a difference when riding 100km or climbing in the alps, but on the types of riding coaster hubs were designed for, they do not have significant drag.
