In the gray area of legality, such as for trip sitters or religious entheogenic ceremony, it remains unclear whether a contract that provides informed consent and waiver of claims would be enforceable—and if the risk of having a contract outweighs the rewards. For the practitioner, disclosing certain information appropriate for the psychedelic space and risks may make clear what the services do and do not include, which allows a participant to make an informed choice about engaging in services that can vary widely in terms of context and container and about alignment with a provider. Transparency and communication through a contract can increase safety, establish standards of care, and improve outcomes for the participant. This workshop will consider strategies for clear informed consent, as well as the risks of the use of a contract, and how it can address ethical issues and mitigate legal risks where services involve activities with controlled substances.
