Yesterday scientists announced that they'd discovered a way to harness the painkilling powers of the active ingredient in marijuana, THC, while eliminating the high. What this means is that a special, non-hallucinatory version of THC could become the new aspirin.

Physiologist Li Zhang and colleagues discovered that THC targets several parts of the nervous system, some of which are called inhibitory glycine receptors (GlyRs). These receptors, according to Zhang, help regulate "neuromotor activity, pain sensation, muscle relaxation and anxiety." He and his fellow researchers speculate that a synthetic THC could be made that targets just GlyRs - hence, a form of cannabis that works as a painkiller but doesn't get you high.
