Below are the primary causes of false positive drug tests:

Medications

• Antihistamines: Over-the-counter antihistamines, such as diphenhydramine, can lead to false positives for methadone or PCP1.
• Pain Relievers: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can cause false positives for marijuana and barbiturates1.

Foods and Supplements

Common Foods

• Poppy Seeds: Consuming poppy seeds can result in false positives for opiates due to the trace amounts of morphine and codeine they contain1.
• Hemp Products: Foods and supplements containing hemp can lead to false positives for marijuana1.

Dietary Supplements

Medical Conditions

• Kidney Disease: Impaired kidney function can also affect drug metabolism and excretion, resulting in false positives1.

Diabetes
