Cannabinoid testing** is used to detect the presence of cannabinoids (compounds found in cannabis) in various biological samples. This testing is commonly used in medical, legal, and workplace settings to determine whether an individual has consumed cannabis.

Risk Assessment for Cannabinoid Testing

- **False Positives**: Certain medications, foods, or health conditions might cause a false positive.
- **False Negatives**: Diluted urine or delayed testing can sometimes result in a false negative.
- **Privacy Concerns**: There is a risk of personal health information being exposed if proper data protection measures are not in place.

Normal Range 

- **Normal Range**: The normal range is typically "negative" for cannabinoids, meaning no detectable levels of cannabis compounds. A "positive" result indicates that cannabinoids have been detected in the sample.
  

Interpretation
  - **Negative**: No cannabinoids detected, suggesting no recent use.
  - **Positive**: Cannabinoids detected, indicating recent or past use. The specifics depend on the type of sample and the testing method used.

Cannabinoid tests can be conducted using various types of samples, including:

1. **Urine**: Most common for workplace testing.
2. **Blood**: Used in clinical settings; shows recent use.
3. **Saliva**: Detects recent use; often used in roadside testing.
4. **Hair**: Can detect long-term use; used in forensic settings.
