Due to differences in their chemical makeup and how they are processed through the body, detection times for various opioids can differ. Heroin is also a semi-synthetic opiate derived from morphine. Unlike prescription drugs, however, heroin is illegal in the United States. Due to similarities in chemical properties, a urine test that is sensitive to heroin-specific metabolites may be required to differentiate heroin use from use of another opioid.
This can result in longer or shorter windows than average for positive test results. Studies have shown that eating poppy seeds prior to taking a drug test can also result in a false positive for opioid use. This is because poppy seeds contain trace amounts of codeine and morphine. If possible, it is best to avoid eating poppy seeds at least 24 hours before taking a drug test.
There are a variety of reasons why a person may be tested for opioid use. Some doctors require regular drug screenings for patients who are prescribed opioids for more than 90 days. This is to ensure they are taking their prescription and to screen for illicit drug use. Drug testing is also common in places of employment. Testing is sometimes required prior to beginning a new job and may continue to be required on a regular basis based on workplace policies.
People with a previous history of substance abuse, or those who are suspected of abusing opioids, may also be asked to take a drug test. Opioids are highly addictive substances that can have devastating effects when abused. As a result, doctors are increasingly encouraged to closely monitor patients taking opioids for signs and symptoms of misuse and addiction. It is common for people struggling with opioid abuse or addiction to be concerned about how long a drug can be detected in their bodies.
