To assist someone in leaving a distressing trip, start by giving them fresh water to drink. If they're willing, hold their hand and talk to them about very concrete things like their work, hobbies, family, or even food. After a few minutes, it's possible to accompany them outdoors for a walk. However, while the person is under the influence of psychedelics, it's important to avoid using anxiolytics, alcohol, or discussing traumatic experience.
