It is a fail.
If you have a non-smoking aquaintence, use theirs.
I was in the same situation a few weeks ago and was on the edge of clean when I HAD to go in (otherwise it would have turned into a hair test). Borrowed some piss (any gender will do). Borrowed an extremely stretchy and firm underwear from wife. Put piss in small, clean, plastic bottle and it was held securely between balls and ass. I could actually jump around with it there. I also practiced quick steady removal, pouring, and replacement.
I drove to the facility with the bottle there stablizing heat. The whole drive I contemplated whether I would use it or not ...but the second I shut and locked the bathroom door, instinct kicked in and I whipped that bottle out did the pour, set glass down, took a long piss in the toilet, put bottle back by taint, zipped up, picked up specimen and the rest us history.
When I got the Passing result 2 days later I was also pissing clean 16 days to clean up. Yep, got toasted at that point.
Bottom line... Dont risk it and at least give youself an option. It was really easy.
