The initial pilot study has been completed, including a published report of subjective effects in 6 volunteers. An 18-subject, double-blind, placebo-controlled study of ayahuasca effects is now complete. Included were measures of subjective effects, cardiovascular effects, sensorimotor gating, EEG variables, urinary monoamine metabolite excretion, and pharmacokinetics of ayahuasca alkaloids.
