A recent study by Lin et al. (2012) looked at how one’s neighbourhood can have an effect on substance use. Specifically, they explored the association between perceived neighbourhood cohesion and alcohol, cannabis, and tobacco use. They found that individuals who perceived their neighbourhood as more cohesive had higher annual frequency of alcohol consumption, but lower consumption on a typical drinking occasion. Higher perceived cohesion was also associated with a decrease in the probability of tobacco and cannabis use and of the amounts consumed. Further, area-level census aggregated neighbourhood cohesion exerted an additional effect on the frequency of tobacco and cannabis consumption over-and-above individual perceptions of cohesion.
