Home Vs. Office

Ok so I have been clean for about 2 weeks now from smoking. I just took a urine test yesterday a wenesday. I too a home test on monday and it said I passed and Wenesday right before I went for the urine test and passed then to. I also made my friend who smokes everyday take the home test and he failed. So I was just wondering if I should really be worrying as much as I am still or is the home test accurate? I used First Check Marijuana. Please write back asap.

Nobody? Please anyone just say you'll be fine or I dont know you might have something to worry about anything please! :)

The home tests are over 90% accurate. You'll be fine.
