Abstract
We used Box-Jekins ARIMA method to identify and estimate a times series model for drug addiction and rehabilitation in Sokoto state. The data set was obtained from NDLEA D. D. R. unit Sokoto State Command. And is for the period 2017 – 2023. Preliminary investigation of the data properties indicated that the series is stationary at the level. Six candidate models were identified to fit the series among which ARMA (2 2) was found to have the best fit with minimum information criterion. Diagnostic checking of the model residuals confirmed the adequacy of the model. The result of the forecast confirmed that drug addiction and rehabilitation cases will continue to persist in the state.
