Compounds responsible for the aroma of cannabis and many other plants may offer a surprising new way to relieve chronic pain.

Unlike THC, these compounds are not associated with psychoactive effects, making them a potentially attractive alternative for pain treatment.
They already did this a long time ago, with Marinol, a course of which costed like 20k, while a 50 dollar baggie of weed would better do the job.
