From San Francisco, California on July 21, 2026

Assumed to be heroin

Only 1 major substance detected:

  • heroin

And we also found traces of acetylcodeine. 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.

Looks = brown, fine, dull, powder
