You cannot inject even pure water intravenously it will cause hemolysis which is damage to your red blood cells, large amounts are even fatal!!!
Ozonated water is acceptable to drink if using distilled water(preferably double distillated) and made from pure oxygen from a medical grade ozonater. The cheap ozonaters with the built in air pumps will pump the water full of nitric oxide so if you are using one of these please use the pure water at the very least to minimise toxic by products!
