Great way to end the substance abuse and addiction unit with this project! In groups, students are assigned a substance/addiction that was discussed in class and divide up the work. It is up to you if you want them to present this in a digital presentation, brochure, etc. - just edit the document to your liking :) I gave my students two periods in class for this, then gave it for homework.
This aligns with the 2015 Ontario HPE Curriculum for Grade 8
