The kid had a first chance to abide by the school rules and chose not to. It’s not like it was a surprise. He just hoped he wouldn’t get caught…and he did get caught…second offense.
Times have changed…there isn’t smoking of any kind permitted on most school grounds any longer…public schools included. But public schools won’t expel a kid for this. Suspend…sure…expel…no.
If this is a private DAY school…then the kid lives at home…and there has to be a public school that will be required to accept him.
