Adverse events (AEs)
Participants were asked whether they experienced any side effects of the study medication throughout the session. Reported AEs were documented and classified according to severity (i.e., mild, moderate, and severe) and relatedness (i.e., unrelated, possibly, probably, and definitely). Primary outcomes were the total number of related AEs, collapsed across severity, as well as the number of related AEs rated as mild, moderate, or severe.
