Passed home drug test on day 12 and day 16, should I be safe after 34 days?

[some]

I've been a heavy smoker for about 14 months. Nearly every day, going through about a half ounce a month. I'm 5'6 190 lbs and never do heavy exercise but I walk sometimes. I got notice of a drug test 34 days in advance. I bought a home drug test (First Check), tried the test on day 12 of no smoking without really any hope of passing. But the line showed up saying it was negative for marijuana. Being skeptical of these results, I bought another home drug test (First Check again) and tested myself on day 16 in a worst-case scenario (first piss in the morning, dehydrated, dark yellow/brownish urine). It came back with an extremely faint line, but a line nonetheless.

Basically, because of the fact that I smoked so heavily for over a year and because of my body fat and lack of exercise, I'm still extremely skeptical of these results. I'm thinking about sending them into the lab for more confirmation.

So my question is, what the fuck? Am I just some freak that gets rid of marijuana really quickly? Do I have anything to worry about on day 34? Is it possible that the marijuana is just sitting in my fat and will later be excreted in urine?

Three days prior to your scheduled U/A, take one more home THC test again using the first-mornings urination. If youre consistently testing negative on the first-mornings urination, youre good to go.

Is it possible that the marijuana is just sitting in my fat and will later be excreted in urine?

Not if youre routinely testing negative under a condition where THCA concentrations would be at their highest (the first-mornings void).
