Trying to identify liquid in syringes?

watch out. it's likely blood mixed w something. some people regularly hide syringes w cocaine and blood, altho there's probably little cocaine left in there it seems to be part of the creepy obscession w all things drug related that can come on the heels of the high. [ users wait til blood 'jumps back' into the syringe, indicating they've successfully entered a vein. sometimes people do not push the entire contents into the vein, maybe to save it? or some even get into a weird in and out' ritual. yep, drugs are glamorous.]

I find it strange that your friend is kind of spying on his daughter whom I assume is of age since she is a nurse. Had your friend thought they weren't hidden, but just kept out of sight of Anyone who might break into her car thinking they were drugs of some sort? But, besides that, I quess the question remains; sounds like B-12 to me too. Your friend should talk to his daughter. Be a good friend and tell him so. Good luck to both of you.

There are a couple of things I can think of. I first thought of betadine which is a rusty reddish brown in color and it is used as an antiseptic wash for the skin to prep for surgery but it would not be pink. It would look more brown or yellow on a white cloth. The other thing I thought of is Vitamin B12 (cyanocobalamine or methylcobalamine). It is a dark red clear liquid that would look pink on a white cloth. I'm not sure if this is what your friend has found but it is given in an intramuscular injection. It is used for pernicious anemia but some doctors give it to boost energy and the immune system.
