is it okay to drink expired soda?

Expiration dates on pop are suggestions. I've drank pop that's 2-3 years expired. No harm here.

OMG no! It turned to poison at 12:01AM on February 14! snort >>>>>

As long as you don't inhale

Of course. You can drink it a year past the expire date and even then the worst thing would be it was a little flat.

When in doubt, buy another one, keep the receipt, return the old one with the receipt, drink the fresh one.

it will just be flat

yes they tend to be a bit flat though

According to the New York Times, expired soda is safe to drink. An article about expired Coca Cola stated that even soda old enough to grow mold poses very little health risk.

No.

The expiration date on most soda is a marketing thing, not a health thing.

It's safe to drink

It's ok to drink. Worst case scenario is that it is flat when opened.

Risk vs. Reward. You're considering making yourself ill over what - $0.50 to $1.20?!

as long as it was never opened ...........................................
