In terms of integration, it’s really hard to know how long it might take to fully process the experiences, insights, etc. of a psychedelic experience. Some things may not get integrated at all, but time & experience are the great integrators. Personally, I like to give myself at several months between psychedelic experiences for integration. This isn’t a recommendation, more a recognition that it takes us time to make sense of and embody important insights. If we have too many insights to process, and not enough time to do so, then the reality is that they don’t stick. When people don’t make time for integration it’s usually a sign that they’re chasing the high. That’s not useful when working with these substances in a contemplative manner.
