After 20 years, NIDA is transitioning away from our beloved Sara Bellum character in the Mind Over Matter series to a format that is more relatable to today’s youth audience. The series will now be called Mind Matters, and will focus on easy-to-understand scientific facts. We want to thank the audience who made Sara Bellum a hit; please be assured that her spirit of inquisitiveness is what laid the foundation for our more modern format. For a limited time, both the Mind Over Matter and Mind Matters series will be available to order or access online.
