Federal officials say there's new funding to study the medical potential of a powerful psychedelic. The effort announced Thursday includes nearly $5 million to lay the groundwork for U.S. studies of ibogaine. Ibogaine is made from an African plant and can cause intense hallucinations, nausea, tremors and dangerous heart rhythms. It's currently illegal in the United States. Veterans groups contend ibogaine has great promise for hard-to-treat conditions like post-traumatic stress disorder, severe depression and opioid addiction. President Donald Trump signed an executive order in April directing federal agencies to speed up review and research of psychedelics.
