I took a .5 mg klonopin on the ninth and have a urine test the 29 will i be clean to pass?

You should be clear: The elimination half-life range for adults is mysteriously wide spread - I've seen it given from 17 thru 60 hours - I'm not sure what would make the difference but yu are well beyond even the longest. Also, although it doesn't seem to matter, if you have a Rx, you would be covered and if you don't - please try to avoid using such stuff as a plaything or to self-treat disease. You should be fine!
