If what youre saying is indeed true, then that "clinic" had BS'd you big time. Urine testing methodologies do not "trace back" a number of days. They do not function in that manner. They only detect the presence of drug metabolites if there are any to detect - regardless of the number of days that the drug metabolites are present.
