Researchersacco and Geneticsalcohol and smoking can be harmful, if not fatal. While the desire for these substances, by environmental stimuli, genomic factors also play an important role. The etiology of these desires is multifactorial and a result of complex interactions with the environment.

The volunteers were from the Saguenay – Lac-St. Jean region of Quebec, the the locale is relatively isolated, somewhat genetically homogenous , and has kept genealogical records of its citizens since the 17th Century, makes the study of complex genomic features facilitate like this.
