My stats: female/ 23/ 5 ft 4 / 115 lbs/ several times a day smoker.
I just wanted to post a bit of a warning really. I read everything on the interwebs which said that as a chronic user I would pass a 50ng test in anthing between a week and 3 months – so I took 1.5 months as an average (but allowed 2 months until my test). I thought people who said 1 week were probably light smokers, and people who took 3 months were heavy people.
Basically passing was a nightmare. It took my boyfriend just two weeks (he smoked less) but I didn’t get a line for 89 days (lost visa, job etc). I ended up exercising, green teaing, lecithining, psyllium husking etc – but who knows if anything worked really.
One possible reason I considered is that women have a higher fat content? (the machine I stood on suggested 17% body fat).
Anyway – tl;dr – just beware that no one’s average…
