Going to school to be a drug counselor, need help on paper?!?!?

The topic of my paper is about the increasing rise of pills on our youth. I need to know if opiate painkillers (oxycontin, vicodin, etc.) are more dangerous then amphetamines (adderall, ritalin, etc.) Which one is blamed for more over doses. I have used google and cant find much if any information on which is worse. Obviously they are both bad but I need to know which one is more responisble for over dose or death in our youth. Paper due tuesday so please help. Thanks!! Also which one is more addictive. They are both addicting so its hard to say which one is more addicting. Thanks for your help. God bless
