Is liquid oxygen safe to drink?

Answer 1

I have a condition known as pectus excavatum where my ribs are depressed and prevent me from taking deep breaths which means I always have a lack of oxygen so I'm taking a trip to visit Father Ralph DiOrio to have faith healing to see whether that can change rib shape and if that doesn't work I need one of you out there to post a name of a black market surgery doctor because regular doctors I visited don't consider it severe enough, insurance considers the surgery cosmetic and it would cost many thousands of dollars so post your b.m.d.'s name list here unless your in law enforcement.

Answer 2

Not possible.  Liquid oxygen is extremely cold −222.65 °C and would freeze your lips and mouth parts to a brittle solid within seconds.  It is an industrial gas and is also extremely flammable.  The slightest spark would set it off.  Also very dangerous to handle.
