You test positive for morphine after you use heroin
They're looking for heroin metabolites. And if you've been using, they'll find them.
No, Methadone will not hide heroin on a drug test.
Heroin is water soluable and should be out of the occasional users body within 48 hours. Some factors may cause the heroin to stay in the body a little longer so the bigger the break between the heroin and the drug test, the better! But lots of water helps and 3 days should be plenty of time.
No, it takes about a week or two to clean that stuff out.
Stop taking heroin.
heroin is cooked into a liquid form in a spoon and then sucked up through a needle, often using q tips or cotton balls as a 'filter' for the heroin, the blood on the cotton ball could have been some of the blood that got into the needle when the person injected themselves, meaning they most likely sucked up heroin through the cotton ball so i'd guess you could test it for heroin.
No, you can't.
