Blood Drug Testing

How acurate are the at home drug test? How long those it take for weed to get out of your system?

So I just smoked some weed on Saturday. And now I have a drug test on Friday (tomarow) I went to walgreens and bought the at home drug test. I took it thinking it was gonna come out with thc in my system. But I came out clean! I was so sure that it was a defective drug test that I even went to buy a new one. But I also passed that one... (on the box said that it is 99.9% accurate). So is it really possible that I am already clean?!? I maybe smoked about 2 blunts.. And I'm not a daily weed smoker last time I had smoked was 2 months ago)

1. Did you get high? Cus maybe you didn't actually inhale it? Or worse it could be that whoever you bought it from didn't actually give you pot. Even if you smoked it and thought you were high it could have been a placebo effect.
2. The home drug test is not going to be as accurate as the one they give you at a clinic. The most accurate is a hair follicle it takes over 6 months for any drug to leave your system no matter how much cranberry juice or the drink that they sell that you drink. It stays in the hair follicle. It is also possible that you didn't read the full instructions. It is also possible that you didn't inhale as much as you thought so it's not registering on the home test version.
3. it usually takes 2-4 weeks to get out of your system but yes its possible that you didnt get enough thc to be dirty
