They probably take a sample of students from every school in your county, so if you go to a particularly “bad” school the stats will be off for you.. but they’re doing it for the county so it’s the overall count they care about. And it may seem that everyone smokes because of the people you hang out with. Make sure you look at everyone in your school, even those kids that sit by themselves at the lunch table!

Same thing happend at my school once too, xcept it went the opposite. My brother has never drank alchohal in his life, and yet, the administrator lady against drugs and alchohal said that all seniors had tried alchohal that year!! Pissed me off, making up lies like that….but frankly, bout 95% of people are gonna do something illegal before they are of age to do it, so….that’s the way life goes ;P
