In the movie Candy, when Candy (Abbie Cornish) overdoses and becomes unconscious, Dan (Heath Ledger) has his friend mix up table salt into a glass of water. He then sucks it up into the syringe and injects it into Candy. After a couple of seconds she comes back conscious and breathing.
I know this has to be twisted a lot because it's a movie. But I want the truth here. If an overdose occurs, does shooting up that person with water mixed with table salt actually help bring that person back to conscious?
