lol sounds like you need to chill out buddy. in my opinion, there is pretty much no way you should have failed. If you aren't a habitual user, I.E. multiple times a week/day, drug tests are barely even a worry. With the amount of smoking you've described, I would say you have nothing to worry about.

In general, two weeks is the maximum amount of time its even possible for someone who's only smoked once or twice in the last 6 weeks to register dirty. Hope this gives you some peace of mind
