April 18 (UPI) -- President Donald Trump signed an executive order Saturday to accelerate research for some psychedelic drugs to treat mental health disorders.

Surrounded by podcaster Joe Rogan and veterans, the president signed the order that could lead to use of the psychedelics in controlled, therapeutic settings.

"We're taking this decision, this decisive step, to confront one of the most urgent public health challenges facing our nation, the mental health crisis," Trump said Saturday in the Oval Office.

"Today's order will ensure that people suffering from debilitating symptoms might finally have a chance to reclaim their lives and lead a happier life," Trump said.

The order directs the Food and Drug Administration to speed its review of new treatments. Trump said the order applies to certain drugs that are already in the "advanced stages of clinical trials."
