> Alcohol and drug use among Inuit increased significantly between 1992 and 2004, particularly among young adults. Alcohol users consumed significantly more alcohol per drinking episode than other Canadians in both time periods. Considerable cannabis use was widespread. In 2004, no significant differences in frequencies of heavy drinking episodes were observed by gender, with 60% of drug users consuming alcohol on a regular basis.

and the link between alcoholism and suicide is well documented:
> Various classical studies found an excess of suicide among alcoholics [73–80]. Beck and Steer [81] and Beck et al. [82] found that alcoholism was the strongest single predictor of subsequent completed suicide in a sample of attempted suicides.
> In 1997, Harris and Barraclough, in their unusually comprehensive meta-analysis analyzed 32 papers related to alcohol dependence and abuse, comprising a population of over 45,000 individuals [34]. They found that combining the studies gave a suicide risk almost six times that expected but with variation of 1–60 times. Specifically, they found that the suicide risk for females was very much greater than for males, about 20 times that expected compared with four for males. Suicide risk among alcohol-dependent individuals has been estimated to be 7% (comparable with 6% for mood disorders; [83]). Of 40,000 Norwegian conscripts followed prospectively over 40 years, the probability of suicide was 4.76% (relative risk +6.9) among those classified as alcohol abusers compared with 0.63 for non-drinkers [84]. Similar finding have been made worldwide [85]. Murphy et al. studied 50 suicides and found that an alcohol use disorder was the primary diagnosis in 23% and a co-occurring diagnosis in 37% [86]. Conwell et al. performed a study in New York City and reported that alcohol misuse was present in the history of 56% of individuals who completed suicide [43].
