The detection period for a urine drug test is up to 3-5 days and results are reported in most cases in 2- 3 days.

The procedure for a urine drug test is simple. A donor provides a urine specimen in a cup to a drug testing collection specialist who will then seal the specimen cup, complete various documentation including a chain of custody form, have the donor initial the specimen cup seal, provide identification and upon completion of the collection and paperwork the specimen will be sent in a secure manner by Currier to the laboratory for testing.

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. Many courts have begun accepting hair testing in place of urine or blood testing and hair testing has been determined to be legally and scientifically admissible evidence in a court of law.

A hair drug test is a simple process whereby a drug testing collection specialist cuts approximately 120 strands of hair from the head or a specific amount from the body and submits the hair to a certified laboratory for analysis. A hair follicle drug test can be screened for a 5 panel, 10 panel or 12 panel test and can also include expanded opiates. If a donor does not have 1 ½ inches of hair on their head, body hair can be utilized, however, if the donor is bald and has none or very little body hair, a hair drug test is not an available option, a urine or oral/saliva test should be utilized.

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: San Marcos, California

San Marcos is a city in the North County region of San Diego County in the U.S. state of California. As of the 2010 census, the city's population was 83,781. It is the site of California State University San Marcos. The city is bordered by Escondido to the east, Encinitas to the southwest, Carlsbad to the west, and Vista to the northwest. Lake San Marcos is an enclave, or county island, in the southwestern part of the city, within San Marcos' sphere of influence but technically an unincorporated community.

According to historical legends, the San Luis Rey Mission flocks were robbed by a small band of Native Americans in the late 18th century. Fleeing the Spanish troops, the Native Americans escaped to the hills. While pursuing the Native Americans, in 1797 the Spaniards came upon a fertile valley, which was named Los Vallecitos de San Marcos (Little Valleys of Saint Mark) to honor the day of discovery: April 25, St. Mark’s Day. On April 22, 1840, Governor Juan B. Alvarado granted Rancho Vallecitos de San Marcos to his relative, Jose María Alvarado. Jose Alvarado was killed at the Pauma Massacre in 1846, and the land was left to his wife; she then sold the land to Lorenzo Soto. In the late 1850s, Soto sold part of his land to Cave Couts, and his family was soon raising livestock. Although Cave Couts owned the land, Major Gustavus French Merriam from Topeka, Kansas, made the first permanent settlement. Merriam homesteaded 160 acres (0.65 km2) in the north Twin Oaks Valley and began wine and honey production.

After Major Merriam’s settlement, German and Dutch immigrants began moving into the area in the early 1880s. In 1883, a few miles south of the settlement, John H. Barham (for whom the present-day Barham Drive is named) founded the first town in the area, originally situated on the southeast corner of what are now Rancho Santa Fe Road and San Marcos Boulevard. By 1884, the town of Barham had a post office, blacksmith, feed store and weekly newspaper. In 1887, the San Marcos Land Company bought almost all of the San Marcos land formerly owned by the Couts family and promptly divided the land into tracts. Soon the hills began attracting home-seekers.[citation needed]
