Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Positive toxicology testing, or ii. Other clinical evidence, such as reliable collateral history (e.g., from caregivers, EMS personnel, or witnesses), physical evidence (e.g., product packaging), or a consistent self-report. AND EITHER b) Symptoms are associated with cannabis exposure and developed during, or shortly after, cannabis exposure; OR c) In the judgment of investigator or designated clinician, the presentation includes symptoms consistent with acute cannabis-induced CNS depression (e.g. respiratory rate depression, increased sedative effects). 3.
