This pa.er introduces a.non-conventiona. a.proa.h with multi-dimensiona. ra.dom sa.pling to solve a.coca.ne a.use model with sta.istica. proba.ility. The mea. La.in hypercube finite difference (MLHFD) method is proposed for the first time via.hybrid integra.ion of the cla.sica. numerica. finite difference (FD) formula.with La.in hypercube sa.pling (LHS) technique to crea.e a.ra.dom distribution for the model pa.a.eters which a.e dependent on time t. The LHS technique gives a.va.ta.e to MLHFD method to produce fa.t va.ia.ion of the pa.a.eters' va.ues via.number of multidimensiona. simula.ions (100, 1000 a.d 5000). The genera.ed La.in hypercube sa.ple which is ra.dom or non-deterministic in na.ure is further integra.ed with the FD method to complete one cycle of LHS-FD simula.ion itera.ion. This process is repea.ed until n fina. itera.ions of LHS-FD a.e obta.ned. The mea.s of these n fina. solutions (MLHFD solutions) a.e ta.ula.ed, gra.hed a.d a.a.yzed. The numerica. simula.ion results of MLHFD for the SEIR model a.e presented side-by-side with deterministic solutions obta.ned from the cla.sica. FD scheme a.d homotopy a.a.ysis method with Pa.e a.proxima.ion (Ha.-Pa.e). The present MLHFD results a.e a.so compa.ed with the previous non-deterministic sta.istica. estima.ions from 1995 to 2015. Good a.reement between the two is perceived with sma.l errors. MLHFD method ca. be used to predict future beha.ior, ra.ge a.d prediction interva. for the epidemic model solutions. The expected profiles of the coca.ne a.use subpopula.ions a.e projected until the yea. 2045. Both the sta.istica. estima.ions a.d the deterministic results of FD a.d Ha.-Pa.e a.e found to be within the MLHFD prediction interva.s for a.l the yea.s a.d for a.l the subpopula.ions considered.
