Donor provided a cold sample that was positive for amphetamines.  An observed collection was positive for cocaine and THC.  I know the observed test should be the test of record, but what should be done with the first out-of-temperature sample?  If it was negative, then I usually just cancel it.  But, since it was positive for a different substance, my concern is if the donor does have a valid prescription then the negative result could cause some issues.  Would it be best to just cancel this result as well?
