Well considering I was not into drugs in high school, well not like ones i would take to prom all i did was drink. We barely even drank there i would save all that shit for the after party. We had some coke alcohol and weed but we stayed largely sober at prom as your around classmates and teachers.
We did however arrive late and leave early... so much so we almost missed pictures LOL
But they did instate breathalyzers and made a effort to curb drinking and drug use before and during prom in my town, just something to consider.
