How long does the effect of Ayahuasca last?

The effects can last anywhere from a few hours to the whole night. The length of time a person feels the effects of ayahuasca varies from person to person and from ceremony to ceremony. Even when the conscious effects have warn off, the medicine continues to work with the body and energetic fields in ways that are not always immediately perceptible. Ayahuasca is a medicine that works far beyond the level of conscious experience.
