The hair drug test is becoming more frequently used by employers, courts and other government agencies due to the fact that the window of detection for illegal drug use for a hair is up to 90 days.

The Opioid Overdose Crisis

Every day, more than 130 people in the United States die after overdosing on opioids. The misuse of and addiction to opioids—including prescription pain relievers, heroin, and synthetic opioids such as fentanyl—is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total "economic burden" of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.

  • Roughly 21 to 29 percent of patients prescribed opioids for chronic pain misuse them.
  • Between 8 and 12 percent develop an opioid use disorder.
  • An estimated 4 to 6 percent who misuse prescription opioids transition to heroin.
  • About 80 percent of people who use heroin first misused prescription opioids.
  • Opioid overdoses increased 30 percent from July 2016 through September 2017 in 52 areas in 45 states.
  • The Midwestern region saw opioid overdoses increase 70 percent from July 2016 through September 2017.
  • Opioid overdoses in large cities increase by 54 percent in 16 states.

In the late 1990s, pharmaceutical companies reassured the medical community that patients would not become addicted to prescription opioid pain relievers, and healthcare providers began to prescribe them at greater rates. This subsequently led to widespread diversion and misuse of these medications before it became clear that these medications could indeed be highly addictive.3,4 Opioid overdose rates began to increase. In 2017, more than 47,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.1That same year, an estimated 1.7 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 652,000 suffered from a heroin use disorder (not mutually exclusive)

Local Area Info: Brentwood, California

Brentwood is a city in Contra Costa County, California, United States. It is located in the East Bay region of the San Francisco Bay Area. The population is 51,481 as of 2010, an increase of 121 percent from 23,302 at the 2000 census.

Brentwood began as a community in the late 19th century, and is still known throughout the Bay Area for its agricultural products, primarily its cherries, corn and peaches. Due to urban sprawl many of the old farms and orchards have been replaced by suburban developments since 1990. Brentwood is increasingly residential, with the rate of population growth in the triple digits during the 1990s and 69% from 2000 through 2010. An official estimate showed the population increased nearly 21% during the period 2010 to 2016.

Brentwood was originally laid out on land donated from property owned by John Marsh, an East Contra Costa County pioneer who acquired Rancho Los Meganos, the land grant that Brentwood is built upon, in 1837 from Jose Noriega. Marsh was one of the wealthiest men in California and was instrumental in its becoming independent from Mexico and part of the United States. His letters extolling the potential for agriculture in California were published in newspapers throughout the East. They resulted in the first wagon trains to California. Marsh encouraged this, and allowed new arrivals to stay on his ranch until they could get settled. Rancho Los Meganos became the terminus of the California Trail. Brentwood was named after Marsh's ancestral home, the town of Brentwood in the County of Essex, England.
