«Opium has been around since the beginning of recorded history, and we'll likely always have opioids because they work so intimately
on pain pathways,» says Gary Brenner, assistant professor in anesthesia and director of the MGH Pain Medicine Fellowship «We just need to do a better job eliminating side effects and building a bigger armamentarium of treatments — so that we can rely less on opioids.»
«It's working directly
on pain pathways in the brain, spinal cord, and periphery,» says Ethan Russo, a neurologist and medical director of Phytecs, a Los Angeles, California — based company developing therapies based on compounds isolated from marijuana.

on pain pathways, as an analgesic does.
