According to the findings, two important principles for the rapid and accurate diagnosis of substance abuseare the amount of substance remaining in the body and the time of the testare very important. Urine, blood, exhaled breath, saliva, sweat, nails, and hair are biological samples that are commonly used to diagnose substance abuse in laboratories.
