Blood Drug Testing

Is there some way that a person can alter the results of a blood drug test so they won't get caught?

I need to know if there is a way that someone can take something or do something to alter the results of a blood drug test. Also, is it true that it will show drugs that could be in your system for the past month?

1. you have messed up. good luck .
2. no, you can't alter a drug test and it depends on the drug as to how long it will stay in your blood system. prescription drugs usually only stay 24 hours
3. If you have a drug test coming up, drink a lot of water, that usually works to clean out your system. Other than that, you're pretty screwed. No way to alter it. you could always find a way for someone else to piss in a cup for you if its a piss test. Good luck to ya.
4. i think thc is the only drug that stays in your system for a month, most others are 48 hours. drinking lots of water only works for urine tests. i would google blood test, i know google'n piss test comes up with 5million hits
