酒精和非法药物的使用是疾病负担的最大风险因素之一，但对药物使用的自然史还有很多不了解的地方。这项研究涉及对世卫组织世界精神卫生调查（WMHS）倡议的数据进行分析，该倡议包含来自31个国家的16万名参与者的数据。这项研究将检查药物使用问题的模式和预测因素，使用新的统计技术预测谁的风险最大。

Alcohol and illicit drug use are among the biggest risk factors for disease burden, but there is much that is not known about the natural history of substance use.

This study will examine the patterns and predictors of substance use problems, using novel statistical techniques predict who is at greatest risk.
