A new evidence-based programme called "Know The Score" is being introduced for teachers to highlight the risks associated with substance use among teenagers.
Cannabis use will also have a particular focus as research shows its use is increasing in recent years among young people.
It has been developed by medical experts, teachers and young people themselves.
Minister Simon Harris said:
“I am delighted to launch this excellent resource which represents an important step in our public health approach towards reducing the harms from alcohol and drugs."
