Researchers in Holland have drawn links between loud music, pot smoking and having “risky” sex.

Meanwhile Ian Dury fans are saying, “DUH!”

The study, published in the Official Journal of the American Academy of Pediatrics, showed that young people who listened to loud music on their iPods were more likely to have smoked pot in the last month. Those who frequently attend clubs and shows were twice as likely to use condoms “inconsistently” during sex. They were also six times more likely to binge drink.

Researchers surveyed 944 students from inner-city vocational schools between the ages of 15 to 25.

“The results provide evidence in support of the integration of risky music-listening behaviors within research on and programs aimed at reducing more traditional health-risk behaviors such as substance abuse and unsafe sexual intercourse,” The study concluded.

Sharon Levy, head of the Adolescent Substance Abuse Program at Boston Children’s Hospital, told Reuters, “We know that high-risk behaviors certainly run together, so in some ways it’s not a big surprise.”
