"Navigating the Workplace: Understanding the Most Common Drug Tests and Their Impact"

The most common types of drug tests used in workplaces include:

1. **Urine Tests**: The most widely used method, urine tests can detect a variety of substances and are often used for pre-employment screenings and random testing.

2. **Saliva Tests**: These tests are less invasive and can provide results quickly. They are commonly used for on-site testing and can detect recent drug use.

3. **Hair Tests**: Hair follicle testing can detect drug use over a longer period (up to 90 days). It's often used for more comprehensive testing protocols.

4. **Blood Tests**: While less common due to their invasive nature, blood tests can provide accurate results regarding current impairment and substance levels in the system.

5. **Breath Tests**: Primarily used for alcohol testing, these tests are often conducted on-site and can provide immediate results.

Each type has its own advantages and is selected based on the specific needs of the workplace policy.
