You don’t have to be a crack dealer to carry a little vial around. I keep a few emergency supplies in mine plus a rolled-up, half-folded $50 for emergencies. There are probably a thousand other little things that can fit in here too.
Keep it in your pocket, on your keychain, or attach it to your EDC (everyday carry gear).
It’s also waterproof, but it will sink if not attached to you.
