Substance use and dependence in the Union Territory of Chandigarh: Results of a household survey using a multistage stratified random sample.

Abstract

Background:Substance misuse is a global health and social problem with major adverse consequences. A number of regional studies on prevalence of substance use and dependence have been carried out in India; but methodologically robust data from Chandigarh are sparse.Methodology:A house-to-house survey was carried out to estimate the prevalence of substance use and dependence in an adequate multistage-stratified random sample in the Union Territory (UT) of Chandigarh, using standardized instruments and predefined measures. Two thousand individuals (1000 each from urban and rural sites) from 743 households were interviewed.Results:Lifetime use of any substance was reported in 21.26% households (8.01% of all respondents; 13.6% males and 1.01% females). Current use was reported in 6.55% of respondents. Prevalence rates of both lifetime and annual/current substance dependence were 2.96% (4.74% for males and 0.72% for females). Alcohol (6.72%) was the most common substance to be ever used by respondents, followed by tobacco (3.34%), opioids (0.17%), and hypnotics (0.04%). Lifetime dependence rates were found to be 1.76%, 2.28%, 0.04% and 0.17% for alcohol, tobacco, hypnotics, and opioids, respectively. None reported the use of cannabinoids, inhalants, or stimulants. Substance users were more likely to be married, employed, and in higher income group as compared to those who never used substance. Only 3.78% substance users had ever sought treatment for the same.Conclusion:Substance use is prevalent in the UT of Chandigarh, with a higher prevalence in males. Substance users hardly ever seek treatment for substance use. This highlights the need of awareness and community-level services for the treatment of substance use disorders.
