Apologies for bumping this but rather then start a new thread I figured I would continue here. I picked up some thc test strips that test for 50ng. My gf just used one this afternoon and it showed a clear negative. She doesnt use that much marijuana. The last time she really used was two weeks ago in the form of tincture. This was a few sprays each day for about 5 days ending about 1.5 weeks ago. Since then she hsingle ad one vape hit and a single Oreo cookie out of a pack of 3. The cookie/vape was last Saturday. Prior to two weeks ago any use was very non frequent. Now five days later the test strip shows negative with a solid (not faint) line.

If this isn't a fluke she would prefer not to substitute at all but I'm wary if this means anything other then she would have passed right now. We have more strips and plan on checking a few times but not sure if we should not substitute. So fat we have done two and both are negative.

How valid are these tests compared to the real deal and what are the chances of this just being a one off fluke? If they all come back negative up until tomorrow morning would she pass a test later in the morning.

My gf has a urine test there this week and we are trying to weigh our options. The paper work says it's an SAP 10-50 w/nit. Does this mean no gc/ms? We have two options, one is substituting someone else's pee(I don't know how to handle storage of this to maintain a good sample). The other option is Canadian Quick Fix with uric acid. Both will be done using a urinator. I would prefer to use the synthetic but have seen a Rating: 5
