Thousands of people cross the U.S.-Mexico border every year to take a psychedelic known as ibogaine. But this isn’t for pleasure, this drug spins most people into a terrifying psychotic trip…but it’s a trip that may help some kick opiate addiction. We follow one man with an addiction issue as he takes this trip, and meet others that are trying to overcome their own drug habits.

Port of Entry is back, this time with a series of stories on how the border can change minds.
