To uninstall Tails from a USB stick, and use it for something else, you have to reset it.

The content of the USB stick will be lost in the operation, but an attacker might still be able to tell that Tails was installed on that USB stick using data recovery techniques unless you securely clean all the available disk space afterwards.
