How to read this table

  • Label said lists the active ingredients on the package, as reported by the source. "No active ingredient listed" means only confectionery ingredients were declared.
  • Lab found lists compounds the lab identified. Red entries were not on the label.
  • No active ingredient detected means nothing the lab screened for was found in that sample. It isn't proof the product contains nothing else.
  • Each row describes the packages that were tested, at that time and place. Other batches may differ.

What's included

We include published, primary sources that report what was detected in specific retail psychoactive gummies (and, where the same study covers them, related chocolates and syrups): peer-reviewed laboratory studies and government testing or warnings. We don't include manufacturers' own certificates of analysis, reviews or user reports. See our editorial policy for how we verify each row. Know of a study or warning we've missed? Tell us.

    Blue Ridge Poison Center (Virginia) managed five people evaluated after eating gummies labelled as containing Amanita muscaria (Sept 2023–June 2024), including a 3-year-old who was hospitalised. Investigators bought six packages of five brands from gas stations and smoke shops; four of six contained unlabelled psilocybin or psilocin, with caffeine, ephedrine, mitragynine (kratom) and DMT among other unlabelled findings.

    Limits: Six packages, one region, qualitative screen; the instrument could not test for muscimol, ibotenic acid or muscarine, so their presence was undetermined. Public domain (MMWR).
