Retest Denied

I'm new to trucking ,was told I failed pre employment drug screen and asked for retest of split ,was then sent home because could not afford.learning now that they could not deny me,went to work with new job and was let go when sent info that I failed,need help not on drugs ,just want to drive

Hey John...was there anything that could be there. Did you take someone else prescription pain killers...or maybe 2nd hand smoke....just thinking out loud. Companies don’t usually ruin someone’s career without offering a second test. Good luck
