Topic guide

Safety & Ethics

Screening, contraindications, professional boundaries, informed consent and the systems needed to protect participants and patients.

Start with context

Safety is more than the acute pharmacology of a substance. It includes selection, preparation, monitoring, psychological vulnerability, professional conduct, complaints, data integrity and long-term follow-up.

Questions this topic raises

  • Who is screened out—and why?
  • What happens if distress or a medical problem occurs?
  • Are professional roles and touch boundaries explicit?
  • Can participants report concerns independently?
  • Are adverse events and limitations reported transparently?
