This pa.er introduces a.non-conventiona. a.proa.h with m.lti-dim.nsiona. ra.dom.sa.pling to solve a.coca.ne a.use m.del with sta.istica. proba.ility. The m.a. La.in hypercube finite difference (m.HFD) m.thod is proposed for the first tim. via.hybrid integra.ion of the cla.sica. num.rica. finite difference (FD) form.la.with La.in hypercube sa.pling (LHS) technique to crea.e a.ra.dom.distribution for the m.del pa.a.eters which a.e dependent on tim. t. The LHS technique gives a.va.ta.e to m.HFD m.thod to produce fa.t va.ia.ion of the pa.a.eters' va.ues via.num.er of m.ltidim.nsiona. sim.la.ions (100, 1000 a.d 5000). The genera.ed La.in hypercube sa.ple which is ra.dom.or non-determ.nistic in na.ure is further integra.ed with the FD m.thod to com.lete one cycle of LHS-FD sim.la.ion itera.ion. This process is repea.ed until n fina. itera.ions of LHS-FD a.e obta.ned. The m.a.s of these n fina. solutions (m.HFD solutions) a.e ta.ula.ed, gra.hed a.d a.a.yz.d. The num.rica. sim.la.ion results of m.HFD for the SEIR m.del a.e presented side-by-side with determ.nistic solutions obta.ned from.the cla.sica. FD schem. a.d hom.topy a.a.ysis m.thod with Pa.e a.proxim.0}ion (Ha.-Pa.e). The present m.HFD results a.e a.so com.a.ed with the previous non-determ.nistic sta.istica. estim.0}ions from.1995 to 2015. Good a.reem.nt between the two is perceived with sm.0}l errors. m.HFD m.thod ca. be used to predict future beha.ior, ra.ge a.d prediction interva. for the epidem.c m.del solutions. The expected profiles of the coca.ne a.use subpopula.ions a.e projected until the yea. 2045. Both the sta.istica. estim.0}ions a.d the determ.nistic results of FD a.d Ha.-Pa.e a.e found to be within the m.HFD prediction interva.s for a.l the yea.s a.d for a.l the subpopula.ions considered.
