Research Summary
Cocaine and amphetamine users appear to develop an abnormal protein in their brains that could play a role in addiction.
Researchers at the Rosalind Franklin University of Medicine and Science in North Chicago, Ill., found that use of these drugs alters a protein that controls how RNA is copied — an anomaly that could cause structural changes in tissues, diseases, and behavior changes.
