Yesterday at approximately 6pm, I had one single Margarita. It was not a strong drink at all, in fact I am a 5'3 female (who is a lightweight) and weigh 130 pounds and did not even catch a buzz. Today at 4pm I have to take an EtG test. I'm worried about passing, I have drank a lot of water today but not enough to cause a dilluted sample. The cut off is 250ng/ml. What are the chances of myself passing?

51/49. What do I win if I'm right? What do you lose if you are wrong? What do you think your chances are since you have already done the dirty deed, and are in the place of wait and see?

You should be fine, but once people have a drink before a test they think they will always be fine drinking before they test. Thats a recipe for disaster at some future point in time.

Please THINK before you drink next time. Is a cocktail worth the wonder?

In many ways I agree, normally you will be fine and may, depending on how much water, risk more of a chance of diluted sample.

But there is a chance it will be picked up, since time is the major factor of the testing.

I have to wonder, why the concern now/ there must not have been concern when you were drinking?
