Abstract
Given that the legalization of marijuana is escalating in many parts of the
world, the impact of Initiative-502 (I-502) in the state of Washington is appraised using
the NERA model (N: Nonuser, E: Experimental user, R: Recreational user, A: Addict).
Data available [12-15], on the prevalence of marijuana use, are used for analysis. To
calibrate the model, genetic algorithm is performed for the periods prior to and post I 502. A rise in the peer pressure that recreational and experimental users exert on
nonusers to try drugs in the post legalization period, is noted. The simulations show
good agreement with the observed data, depicting the efficiency of NERA. Additional
numerical investigations are conducted and the experiments show a growing tendency
towards the population of marijuana users post I-502. The concept of targeted
campaigns of prevention is explained and the effect of implementing such campaigns
of prevention 1 year before I-502 on both the experimental and recreational users is
examined. The numerical illustrations demonstrate a decline in the proportion of
marijuana users when such campaigns of prevention are enacted 1 year prior to I-502.
The present study provides a more feasible insight into the impact of I-502 and
furnishes valuable perspectives to assist the health authorities in addressing the
complex issue related to the rise of marijuana consumption. These findings can be
useful to other states and countries considering changing the legality of marijuana use. <br>
