And for me It's alot longer, I took a test, GC/MS on July 29, it came back at 44 ng/mL. Took another test, GS/MS on Aug. 18, 20 days later and It came back at 20 ng/mL. So the Half-Life in me is about twice as long.
Now I know everyone is different, I'm in my 40s, 5'10 160. and have been painting my house, not like I sit around all day. I was smoking a lot of top dollar week, about a gram a day for years. I was able to pass a home test after 19 days. My test on the 18th. was after 58 days. At this rate it will be another two months before I'm at Zero ng/mL
