Hey guys,

I don't smoke or do drugs other than alcohol. I was on a work trip a few weeks ago and got way to drunk. Went home to a girls house and stayed with her.

I don't remember much of the night but vaguely remember her having some weed/trying to roll something and smelling weed smoke. I'd like to think I wouldn't of been stupid to smoke any because my job has random drug tests but I'm just not sure.

Obviously I was exposed to some second hand smoke I think, but I'm hoping like hell I didn't smoke any.

My questions is... I have a drug test in the next few days and am shit scared. This happened almost exactly 3 weeks ago. If I did smoke a tiny bit(fucking hope I didn't, surely not...) then am I fucked?

If so any hope for me?

FYI I believe the testing is pretty stringent, it is urine based and seems rather high tech.

Thanks for any comments or help.
