K2 (Synthetic cannabinoids)
Synthetic cannabinoids, known as K2 or Spice, are lab-made chemicals sprayed on plant material that mimic THC but are often stronger and riskier.
Detection window: Usually detectable in urine for about 1-3 days, longer with heavy or regular use.
How Testr tests for it
This panel is part of every Testr visit. A certified collector observes the collection at your home, checks specimen temperature, and reads a clinical 13-panel cassette on the spot. For measured levels rather than a positive/negative read, add laboratory confirmation: a certified lab quantifies the result and an independent Medical Review Officer reviews it before release.
