Here are my results negative for marijuana after 13 days. However no indication of how many ng were found.

SO for a recap. I am 6'3 195 lbs. I am active and have low body fat. I am a chronic smoker for 6 years now. smoke probably more then a joint a day. stopped smoking for 14 days. I drank a lot of water and cranberry juice. I worked how twice a day doing cardio, did not lift weights because I don't sweat enough.
Took the firstcheck test and passed..

I hope this was helpful for all my pot smokers. keep smoking but do it smart!!
