No, as long as you're doing fine in school, whatever problems you have outside of school is none of your schools bussiness.
For instance, if you're smoking weed every friday after school, your school has nothing to do with it, unless it affects your grades, and tbh i think even your grades are your own damn responsibility, the school is there to provide teachings, and responsible for providing good lessons and help with said lessons, you're responsible for doing your homework, and following the lessons.
But back to the weed, the school shouldn't do shit about it, they should complain to you if your grades are falling, and tell you to get your shit togeather or gtfo, and then it's your own responsibility, to stop smoking IF it's the weed thats your problem, which it doesn't have to be. (i smoked durring high school and still got the best grades in the class)
