This film shows a poster being hung up at a college wall inscripted with marijuana’s apology. During the day, students, teachers and everyone else walked by the poster without reaction. When someone notices it, gets annoyed and rips it off the wall. Underneath the previous pôster there was another one that said: By the time someone does something, drugs will already be in schools. Sign: Talking to your children is the best way to keep them away from drugs.
