The Prom is a yearly social event commemorating students’ completion of high school.

While this in itself may seem like a good reason to celebrate, other activities at the Prom indicate it’s not just about academic achievement.

Sex, drugs, rockn’ roll and lots of alcohol are four crucial elements of Prom night. But it doesn’t stop there. Ask Shaema Imam, 21, who attended her 1994 Prom.

“It’s not just the drinking, it’s not just the hotel room and sex part, it ‘s the whole atmosphere that’s created where alcohol, dancing and varying degrees of nudity are correlated with a good time,” says the McGill University student.

It is also big business.
