My husband and I have been talking about this and are curious what everyone else thinks: we are both iv drug users and I have a really hard time hitting due to shitty veins so I generally end up with a lot of blood in my shots before I am able to hit and once the shot is diluted with blood it seems to basically be as if I'm shooting water and my husband agreed with me after trying it also. I don't mean like a weak shot either I mean it literally feels like nothing is in it when his undiluted shot (that was originally equal to mine) rocks him hard. What could my blood possibly be doing to it?
