Should I worry?

Hi Ya all,
I have a UA 5 full days from now and probably shouldn't have anything to worry about, but what do ya all think. I smoked 1 toke, and I mean absolutely 1 single toke. Yes, it was some of the best quality I've seen in a long time, but still, only 1 single hit. I'm a small man (125 lbs.) 54 years old, don't drink alcohol or take other substances and haven't smoked in over a year. Even when I smoked over a year ago I only did so once every few weeks and it was 1 or 2 hits. So I'm probably not going to test positive I would think?

The "one-hit" topic has been addressed and answered dozens of times throughout the forum (and at least twice this past week alone).
