Teachers in West Yorkshire are going back to school to learn how to spot pupils who are using drugs.
Teachers will be taught about the effects of drugs
The event at Bradford's Odsal stadium has been organised by West Yorkshire Police to help teachers understand the issues surrounding drugs.
The day-long event will also look at ways to combat peer pressure on youngsters to experiment.
Force drugs co-ordinator Bryan Dent said it was vital that teachers were better informed.
"Teachers work in such close proximity with children on a daily basis that their understanding of drugs issues is vital," said Mr Dent.
"They could be the early influence that diverts kids away from drugs before they succumb to curiosity or pressure. For this reason we want to provide them with as much support as possible."
Members of the Bradford Bulls rugby league team will also give teachers a talk on healthy lifestyles on Wednesday.
Among the events planned is a workshop on recognising different drugs and their effects.
