A paper by Shizhong Han and colleagues in the current issue of Biological Psychiatry implicates a new gene in the risk for cannabis dependence. This gene, NRG1, codes for the ErbB4 receptor, a protein implicated in synaptic development and function. The researchers set out to investigate susceptibility genes for cannabis dependence, as research has already shown that it has a strong genetic component.
