SOUTH BEND, Ind. -- Students from across the United States marched for drug prevention in downtown South Bend for the Pride 2013 World Drug Prevention conference.

Their goal is to help teens with drug and alcohol prevention. 

Pride Youth Programs sponsored Wednesday's conference.

The group says the peer to peer relationship is important and that teens often spend the most time with their friends.

"Being able to create a relationship with your friends, that is something where you don't have to put a mask on and be somebody different around them is very important, especially when it comes to the drugs and alcohol," said Ben Schultz, international trainer.

The biggest thing the group wants teens to know is that they can be the change in the world.
