Use clear, participant-centered communication

The manuals converge on the need for communication that is easy for participants to follow. Across the extracts, the sources recommend clear, accessible, concise, and direct language, with an emphasis on avoiding jargon, overly theoretical or abstract discourse, and communication that becomes confusing or hard to track. They also share a concern for adapting communication to the participant’s state, whether that means clarifying when something has not landed well, or adjusting wording and intensity to comprehension, orientation, or altered-state capacity. The sources differ mainly in emphasis and setting. The MDMA manuals focus on in-session communication, especially during altered states, and describe brief, concrete, supportive exchanges, simple check-ins about tolerability, needs, and safety, and a tone that supports calm and orientation. The 5-MeO-DMT manual places more weight on pre-session orientation and informed preparation, including written materials, direct communication, explanation of restrictions, and timely answers to questions. It also explicitly mentions communication by writing, phone, email, or structured orientation, which is not specified in the other extracts.
