Provide overnight and next-day containment

The manuals converge on the need for care to continue beyond the acute dosing session, with observation, support, and readiness to respond to problems extending into the post-dose period. Across the extracts, this includes inpatient or supervised settings, overnight monitoring, next-day contact, and discharge only after safety and recovery have been established. They also agree that containment is not limited to passive watching, but includes active follow-up. The sources mention rapid response to distress or psychiatric destabilisation, overnight checking by an attendant, morning integration or integrative conversation, and continued availability by phone or pager after the session. Several manuals link this continuity directly to safe discharge and transport. The main differences are in how long this containment lasts and how it is organised. Some sources emphasise overnight stay and next-morning review, while others extend monitoring for many hours, a full day, or several days after dosing. The setting also varies, from a physician’s office to a supervised inpatient psychiatric environment, and the type of monitoring differs by substance, with some extracts highlighting psychiatric observation and others focusing on cardiac, neurologic, or withdrawal-related effects.
