The same majority of the high court also ruled on Monday that public schools can prohibit student expression that can be interpreted as advocating drug use. The case centered on a high school student in Alaska who was suspended for holding a sign that read Bong Hits 4 Jesus at a parade during a school trip. In his dissent, John Paul Stevens criticized the majority of the court for inventing out of whole cloth a special First Amendment rule permitting the censorship of any student speech that mentions drugs.
