Drug addictions plague about 22.5 million Americans, according to recent statistics. But promising scientific research may one day begin to whittle away at that number, say scientists writing in a special issue of the journal Neuron published Wednesday.
The issue is devoted to addiction and details many of the latest theories about substance abuse prevention and treatment. Included in the journal (online access is free for this issue) are papers on opioid prescriptions for chronic pain and the risks involved; how drugs might be used for cognitive enhancement and how obesity is linked to other addictions."
