About 150 Queechy High students recently attended a lecture at the school by Drug and Alcohol Research and Training Australia educator Paul Dillon, followed by a presentation for parents.

Mr Dillon said parents often said they did not talk to their children about drugs and alcohol because they thought it was pointless, but that was a false assumption.

"Kids genuinely do care what their parents think," he said.

"The best way we know to protect our kids is meaningful, quality conversation.

"Parents have influence."

Queechy health and wellbeing teacher Brad Cottam said the presentation was part of the school's drug education program.

"It's about making sure that they are safe and controlled in any situation they get into," he said.

Mr Cottam said teachers recognised that alcohol was part of society so students needed to be educated about the consequences of alcohol consumption.

Mr Dillon has just published a book called Teenagers, Alcohol and Drugs, which answers common questions from youth and parents.
