Drug and Substance use continues to be a major public health and socioeconomic problem worldwide. In 2014 the World Health Organization (WHO) estimated that total worldwide substance use would consist of 2 billion consumers of alcohol, 1.3 billion smokers and 185 million users of other drugs in the near future. The WHO further reports that global burden of disease due to alcohol and illicit drug jointly contributed to 12.4% of all deaths in 2000 and 8.9% of total years of lost life.
