Hey,

I had a joint 21 days ago (At the time of my drugs test) with my brother, and 2 puffs off another joint over a month ago, Before those the last joint I had was November, And I had my drugs test on 4/30/12

I had hit the gym often (3-6) times a week and go out bike riding for a mile or 2 depending on the weather before I had my test.

I'm wondering on what my chances are of passing this test? I drank plenty of water daily/Cranberry juice.
I took a home test and passed it with a strong pink line on first void of the day now it was at 50ng, I found out today that the test I took for my new job is for 15ng/20ng do you reckon this should still be a pass for me? Based on how I've been since I last smoked?

My dad tried so hard to hook me up with a job, If I fail not only is my chance gone but his career is out the window as well.

Any advice is greatly appreciated.
Here is some info I found from the drug testing company: 284300 http://i49.tinypic.com/jzb9rn.jpg

Ahh I think I'm starting to get it, So 50ng is pretty much similar to 15ng for the GC-MS, So passing at 50ng would make you a pass at 15ng? And they'd only use it if you have a positive on the first strip test.

Thanks for this, Only think worrying me is if they test straight for 20ng rather 50ng as I'm genuinely worried sick to if I'll pass at a 20ng.
