Will I pass a drug test?

I recently applied for a job where I may have to take a urine drug test. Today I was cleaning out my smoking utensil (being unemployed and bored I decided to do some spring cleaning) and I disassembled it, cleaned it out the best I could, reassembled it, and breathed through it to make sure everything was working ok. Long story short, some old ashes ended up in my mouth and for about a half hour I felt light headed and a bit dazed. Do you think this could effect my drug test? Besides this, I haven't smoked in about 5 months.
