have done marijuana and have had it negatively effect your grades/work/or other stuff. Or mybe know a friend who does marijuana and has had his grades slip or whatever.

From my experience of me and my friends doing it doesnt seem to bad. My grades have stayed the same, mybe even gone up a lil. Most my friends didnt care about school before they started and still dont know.

Id appriaciate you only answering from personal experiance, or from observance.Not from what your teachers/parents told you or what you learned in health class. Also please dont tell us how bad drugs are for us, we know.
