In the multivariate Cox proportional hazard regression model, Uigur people (HR, 1.50; 95% CI, 1.25-1.80), smoking cigarettes beginning from less than 15 years old (HR, 2.12; 95% CI, 1.77-2.55) and relatives involved in drug use (HR, 1.36; 95% CI, 1.05-1.75) were the factors independently associated with initial drug use.
