About The Contest
This is your chance to make prevention visible.
The In The Weeds Poster Contest, powered by PreventEd, invites students in grades 9 – 12 to explore how creativity can shape conversations about cannabis prevention and youth health.
Through art, we can change how people think, feel, and talk about substance use. Submitted posters should encourage positive decision-making, self-expression, and care for your community — using fact-based messaging, not opinion or promotion.
The winning poster will receive a cash prize and be featured in a St. Louis-area awareness campaign, appearing across social media, digital placements, and print materials as part of PreventEd’s In The Weeds initiative.
Who Can Enter: Missouri students in grades 9 – 12
Entry Fee: Free
Media Accepted: Digital or hand-drawn artwork (submitted digitally)

Talk About It
Through a supportive environment, GuidEd enhances motivation to change, helps explore the consequences of substance use, and works to develop healthier alternatives.
Initiation of cannabis use is common during the high school years. It’s Complicated is a cannabis peer-teaching program for high school students.
Prevention, Education and Support is for adults too. Our Adult Assessment connects adults with the resources to make positive changes in their lives.
Our Talk About It campaign focuses on the use and misuse of drugs and alcohol and is dedicated to giving families the encouragement, resources, and tools to have these life-changing discussions.
