Passing a blood drug test is different than passing other types of drug tests because they are more invasive, costlier to the entity ordering the test, an are testing for drug toxins and perhaps alcohol or nicotine that have been in your body recently rather than over the course of several weeks like hair drug tests and urine drug testing.
So what does this mean for you? Well, chances are, if you are asked to give a blood sample to pass a drug test on the spot, you aren’t going to pass if you have very recently used the drugs that are being tested for. That said, if you used marijuana two weeks ago and the blood drug test is testing for marijuana use, you’re going to pass–unlike a urine drug test which you would still have a chance of failing even after two weeks of abstaining unless you had used a drug detox product.
In order to pass a blood drug test, you need time to properly detox your body. This can be done more quickly with a short or long term body cleanser. Simply follow the instructions on the labels of the body cleansing product(s) you will be using for your detox. Eating a balanced diet and engaging in some good, well balanced cardio and other reasonable exercise is also a good idea during this process. And of course, stay hydrated, but if you think you might also be asked for a urine sample, do not drink too much water as your test will come back as diluted.
Good luck to all on your journey through passing a drug test!
