Can tonic water be used after the expiration date?

Tonic water can usually be consumed after its expiration date, as it may still be safe to drink for a while, especially if it has been stored properly. However, its flavor and carbonation may degrade over time, affecting the overall quality. It's best to check for any off smells or unusual appearance before consuming it. If the tonic water tastes off or has changed significantly, it's advisable to discard it.
