i, like you have been a 17yr smoker. I knew a test would be up comming so I stopped. 15 days after i took a home test and failed, so I used QF to sub my UA. I passed. I do not start my new job until Oct 1st. So no smoking until then.

45 days clean I get decent, but not solid line on home tests. Everyone is different.

Follow the dilution method posted above. I would think with 5 weeks clean, a mild dilute ( 40oz of Gatorade ) should be fine for you.

Give mid-stream sample, and do the test later in the day if you can.

Good luck!
