I had 3 beers and 1 shot of 30 proof tequila.. I am 5 ft 9" and about 130 pounds and I would say I have a pretty high metabolism.. my last beer was at 2 am on Saturday night and I just took a test today (monday) at 5pm (39-40hours from last drink).. will my test come back negative?

Nope. Most likely positive. They sensitive for about 60-80 hours and you fall well short of that.

What happens if you fail?
