Why does addiction vulnerability differ from individual to individual? For the first time, scientists have shown in selectively bred animals that the propensity for addiction is linked to differences in expression of genes for specific molecules in a specific brain region. It's also the first demonstration that a DNA tag called an epigenetic marker can predispose an individual to addiction and relapse.
