Substance abuse is the harmful or hazardous use of psychoactive substances including alcohol, illicit drugs, and prescription medications. It is caused by repeated exposure to addictive substances that alter brain chemistry, creating physical and psychological dependence. The Dextro/Levo Methorphan LC/MS/MS Urine test is the most important test for detecting dextromethorphan abuse from cough suppressant medications.

Substance abuse is caused by repeated exposure to psychoactive substances like alcohol, opioids, stimulants, benzodiazepines, and over-the-counter medications like dextromethorphan that alter brain chemistry. These substances hijack the brain's reward system by flooding it with dopamine, creating powerful cravings and compulsive drug-seeking behavior. Over time, the brain adapts to the presence of these substances, leading to tolerance, physical dependence, and withdrawal symptoms when use stops, making it increasingly difficult to quit without professional help.
The Dextro/Levo Methorphan LC/MS/MS Urine test is the most important test for detecting abuse of dextromethorphan-containing cough medications because it uses advanced mass spectrometry to identify elevated levels of both dextro and levo methorphan metabolites in urine. This specialized test is essential for identifying people who are misusing over-the-counter cough suppressants for their dissociative and hallucinogenic effects. Comprehensive drug screening panels that test for multiple substance classes including opioids, amphetamines, benzodiazepines, cocaine, and cannabinoids are also valuable for monitoring substance use in treatment programs and detecting polysubstance abuse patterns.
You should get tested if you are entering a substance abuse treatment program, participating in addiction recovery monitoring, or have concerns about misuse of prescription medications or over-the-counter drugs like cough suppressants. Testing is also important if you are experiencing unexplained behavioral changes, cognitive impairment, or physical symptoms that might indicate drug use. Many employers, healthcare providers, and legal systems require regular substance abuse testing to ensure compliance with treatment plans and safety protocols.

What this means
Your test came back negative, meaning no dextromethorphan was detected in your urine sample. This indicates you have not used products containing dextromethorphan recently, or levels are below the detection threshold. This is the expected result if you haven't taken cough medications in the past few days.
