Smoking would increase sensitivity to stress

Researchers from the Institute of Biology Paris-Seine (Neuroscience Paris-Seine) and the Institut de Pharmacologie Moléculaire & Cellulaire (Sophia Antipolis, Valbonne) have investigated the relationship between stress and nicotine. and show that smoking increases sensitivity to stress, due to an action on a7 nicotinic receptors. These results have been published in Molecular Psychiatry. [...]
