Understanding TSA Rules for Pepper Spray

What Is Pepper Spray and Why It Matters
Pepper spray uses capsaicin to disable threats by causing intense eye, nose, and skin irritation. It’s non-lethal, compact, and widely used by civilians and law enforcement. If you’re traveling for business, hiking, or just want peace of mind, it’s important to know how to carry it legally and effectively.
