Hello! I posted a few weeks ago and you guys eased my mind about my drug test. Now that it is ONE WEEK away, I have started worrying again =( Here are the few questions I have, any info at all would be appreciated! I am 21, smoked for 5 months everyday before stopping totally in mid december, i am very overweight with a slow metabolism 5'0 and 180lbs. I believe at time of test I will have been 100% clean for 217 days.

1) I want to ease my mind and take a at home drug test. I won't order online since I am still living with my parents. Where do you guys get them typically, I went to a few drug stores near here and can't find any that carry them in their physical inventory.

2) I read something about fat solublity and have lost about 20 pounds from jan to mar, and then gained about 30 from mar to now (oops!), a good chunk recently with the start of summer since ive been eating badly. will that have any adverse effects on this test?

3) How do I know if this is a DOT test that I keep reading about, it is with a defense contractor for the government. (anyone hear of these ever being hair tests?) And do they have like crazy low cut off limits or something?

I think that is about it. Anything you guys got will help me out!
