Which drug show up as thc if i don't smoke but take precription drugs may one of the drug i tale will show up?

Only if marinol: Which is a legal pill form of thc. There are some medications which can give false positive results for thc on screening tests, but whoever is testing you should be sending the positive screen for confirmation by more sophisticated methods (gc/ms or lc) which can determine specifically whether thc is present. Other than marinol, no true positive test results from other medication.
