When I was in high school in the 80s, there was a designated outside area that was the student smoking zone. The school newspaper office was over it and we would occasionally fire paperclips at them with rubber band slingshots. We talked about but never actually did throw water balloons down there, mostly because it seemed likely to result in violent retribution (the paper clips rarely hit their marks or garnered any reaction if they did).

One of my teachers smoked in his classroom during the lunch break and when we came into the room (we had him right after lunch), the room positively reeked of cigarette smoke. Young folks today have no idea just how wild the twentieth century was.
