they may or may not, depends on the school a lot of times, either way, just find out, ask some of the more senior players. By a detox drink, and keep it handy.
i am pretty sure they drug test all NCAA acthletes. I know someon that plays D1 golf and they drug test him once at the begging of the season. I assume they will do the same for you
eh, football players get caught all the time and nothing ever happens to them. Maybe a one PLAY suspension or something. Then again, football is more important than golf at most schools.
