In 1701, Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit, the future city of Detroit. During the 19th century, it became an important industrial hub at the center of the Great Lakes region. With expansion of the auto industry in the early 20th century, the city and its suburbs experienced rapid growth, and by the 1940s, the city had become the fourth-largest in the country. However, due to industrial restructuring, the loss of jobs in the auto industry, and rapid suburbanization, Detroit lost considerable population from the late 20th century to the present. Since reaching a peak of 1.85 million at the 1950 census, Detroit's population has declined by more than 60 percent. In 2013, Detroit became the largest U.S. city to file for bankruptcy, which it successfully exited in December 2014, when the city government regained control of Detroit's finances.

However, when screening drug use within the last 5 days the urine test continues to be the most accurate test.

Hair Follicle Drug Test Process

The procedure used to perform a hair follicle test is simple, the drug testing specialist will cut approximately 120 strands of hair (not really a lot) utilize a chain of custody procedure and send the hair to a certified laboratory for analysis. Drug testing centers require at least 1.5 inches of hair to perform this test and the hair generally needs to come from the head, however if the donor does not have head hair certain testing centers can use hair from chest, leg or arm pit.

If a donor has no hair on their body, than a hair test cannot be performed!

Hair Follicle Drug Test Results

AI Overview

Hair Follicle Drug Testing: An Overview

Hair follicle drug testing is a method used to detect the use of illicit drugs or the misuse of prescription drugs over an extended period. Unlike urine tests, which can detect recent drug use, hair follicle testing provides a longer window of detection, typically up to 90 days. This overview explores how hair follicle drug testing works, its applications, and its benefits.

How Hair Follicle Drug Testing Works

The process involves taking a small sample of hair, usually from the head but sometimes from the body if scalp hair is insufficient. The hair is tested to identify drugs and their metabolites, which are deposited in the hair from the bloodstream. This method is sensitive to a wide range of substances, including marijuana, cocaine, opiates, methamphetamine, and phencyclidine (PCP).

Applications of Hair Follicle Drug Testing

  • Employment Screening: Many employers use hair follicle testing as part of their pre-employment screening processes and in regular checks to ensure a drug-free workplace.
  • Legal and Forensic Cases: This testing is used in legal settings to provide evidence in custody disputes, DUI cases, and other legal matters requiring proof of drug use.
  • Rehabilitation Monitoring: Health care providers and rehab centers use hair tests to monitor individuals recovering from drug addiction.

Advantages of Hair Follicle Drug Testing

  1. Long Detection Period: Can detect drug use for up to 90 days, making it more effective for identifying long-term drug use than other testing methods.
  2. Tamper Resistance: The nature of hair sample collection makes it difficult to tamper with or substitute samples, providing more accurate results.
  3. Non-invasive: The process is simple and does not require the handling of bodily fluids, making it less invasive and safer to administer.

Considerations and Limitations

While hair follicle drug testing is highly effective, there are considerations to keep in mind:

  • Growth Rate Variability: Hair growth rates can vary from person to person, potentially affecting the detection window.
  • Potential for External Contamination: Drugs can sometimes be absorbed from the environment, leading to potential false positives, though washing the hair sample prior to testing can mitigate this risk.
  • Cultural and Personal Concerns: The requirement of hair samples can raise concerns among those with hair loss or individuals whose cultural practices affect hair grooming or styling.

Hair follicle drug testing is a reliable and comprehensive method for detecting drug use over an extended period. It is widely used across various sectors for its accuracy and tamper-resistant methodology, making it a valuable tool in maintaining drug-free environments and supporting legal and medical interventions.

Local Area Info: Detroit

Detroit (/d??tr??t/, locally also /?di?tr??t/; French: Détroit, lit. 'strait') is the largest and most populous city in the U.S. state of Michigan, the largest United States city on the United States–Canada border, and the seat of Wayne County. The municipality of Detroit had a 2017 estimated population of 673,104, making it the 23rd-most populous city in the United States. The metropolitan area, known as Metro Detroit, is home to 4.3 million people, making it the second-largest in the Midwest after the Chicago metropolitan area. Regarded as a major cultural center, Detroit is known for its contributions to music and as a repository for art, architecture and design.

Detroit is a major port located on the Detroit River, one of the four major straits that connect the Great Lakes system to the Saint Lawrence Seaway. The Detroit Metropolitan Airport is among the most important hubs in the United States. The City of Detroit anchors the second-largest regional economy in the Midwest, behind Chicago and ahead of Minneapolis–Saint Paul, and the 13th-largest in the United States. Detroit and its neighboring Canadian city Windsor are connected through a tunnel and the Ambassador Bridge, the busiest international crossing in North America. Detroit is best known as the center of the U.S. automobile industry, and the "Big Three" auto manufacturers General Motors, Ford, and Chrysler are all headquartered in Metro Detroit.

In 1701, Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit, the future city of Detroit. During the 19th century, it became an important industrial hub at the center of the Great Lakes region. With expansion of the auto industry in the early 20th century, the city and its suburbs experienced rapid growth, and by the 1940s, the city had become the fourth-largest in the country. However, due to industrial restructuring, the loss of jobs in the auto industry, and rapid suburbanization, Detroit lost considerable population from the late 20th century to the present. Since reaching a peak of 1.85 million at the 1950 census, Detroit's population has declined by more than 60 percent. In 2013, Detroit became the largest U.S. city to file for bankruptcy, which it successfully exited in December 2014, when the city government regained control of Detroit's finances.
