Marijuana is increasingly being recognized for its medicinal and therapeutic benefits both in the U.S. and abroad, but it’s only one of the many natural psychoactive plants that humans have harnessed for the purpose of healing. The modern War on Drugs has deemed that all mind-altering substances are harmful for individuals and society at large, but in our new series Healing Powers, we travel the globe to show how people have been using "drugs" for as long as recorded history — both to heal mental ailments as well as support more conscious connections to the world around us. Watch as Mareesa Stertz personally participates in psychedelic and healing experiences, learning first-hand of the restorative powers of cannabis, psilocybin mushrooms, ayahuasca, and other plant-based tonics, while meeting some of the individuals embracing alternative forms of medicine in an ever more pharmaceuticalized world.
