What Is a Urine Drug Screen?

In California, urine drug testing reviews the presence of drugs and their breakdown products in a urine sample. This method is widely preferred in workplace and regulatory environments due to its non-intrusive nature, economic value, and extensive coverage of substances within a useful detection timeframe.

  • Ensures sampling is conducted under chain-of-custody protocols for compliance.
  • Offers detection of both the parent drugs and their metabolites as they are expelled in urine.
  • Reflects prior drug exposure during the detection window rather than current intoxication levels.

What Is a Hair Drug Screen?

In California, hair drug testing involves analyzing a small section of hair to find drugs and their metabolites that have entered the bloodstream and become encapsulated in the hair shaft. Due to hair's slow growth, which captures drug metabolites for extended periods, it offers the longest detection window, making it highly effective for uncovering habitual or long-term substance use.

  • Typically need to obtain about 100-120 strands from the scalp region, close to the roots (roughly 1.5 inches long).
  • Depicts an approximate detection window of 90 days, contingent upon hair length.
  • Can detect a spectrum of substances including amphetamines, opioids, cocaine, cannabis, and PCP.

Detection Windows

In California, hair drug testing exhibits the most extended detection interval among drug testing strategies. A usual 1.5-inch section of hair relates to approximately 90 days of drug exposure, with longer samples potentially covering more, given that hair grows at about 0.5 inches per month. Compared to urine or oral fluid analyses, hair tests do not identify recent usage, typically within the last 7–10 days.
