805142

From Portland, Oregon on July 8, 2024

Assumed to be fentanyl

2 major substances detected:

  • bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate
  • acetanilide

And we also found traces of xylazine. Trace substances in small quantities are usually harmless but can sometimes cause health problems. Unexpected sensations may be due to these. The trace designation indicates the conclusive identification of the substance at a relatively low abundance compared to the sample's primary component(s). A substance is designated as "trace" when the peak height is less than 5% of the height of the most abundant peak detected in the sample.

Xylazine causes serious skin problems. These can happen anywhere on the body and don't heal quickly. And, xylazine can come on stronger than traditional dope and knock you out, so be mindful of your surroundings. It's best to avoid dope with xylazine. You might need medical attention to prevent long-term damage.
