Drugs of abuse are illegal or prescription medicines that are taken for a non-medical purpose. Non-medical purposes for a prescription drug include taking the medication for longer than your doctor prescribed it for or for a purpose other than what the doctor prescribed it for. Medications are not drugs of abuse if they are taken according to your doctor’s instructions.

HOME RAPID TESTS These tests indicate if one or more prescription or illegal drugs are present in urine. These detect the presence of drugs such as marijuana, cocaine, opioids, barbiturates, methamphetamine, amphetamines, between others.
These tests are qualitative tests – those find out if a particular drug may be in the urine, but not how much is present.

Home rapid tests are fairly sensitive to the presence of drugs in the urine. This means that if drugs are present, you will usually get a preliminary (or presumptive) positive test
