Researchers at the University of Geneva have found that people who use ketamine for long periods of time are unlikely to become addicted to it. The group published their findings in Nature journal, describing their research on the effects of the synthetic compound and its effect on various brain regions. Rianne Campbell and Mary Kay Lobo from the University of Maryland School of Medicine published a News and Views article in the same journal that outlines the work of the Swiss team.
