Brief Report: Improving Police Conceptual Knowledge of Mexico’s Law on Cannabis Possession


Background and objectives

Policing practices do not reflect recent decriminalization of drug possession in Mexico. We assessed knowledge of cannabis law as part of a police education program (PEP) post-drug law reform in Tijuana.


Officers took pre-/post-PEP surveys; random subsample (n = 759) received follow-up assessments. Longitudinal logistic regression (pre-, post-, 3-months post-PEP) measured knowledge of cannabis law.


PEP increased conceptual knowledge of cannabis law from baseline to post-training (AOR = 56.1, CI: 41.0-76.8) and 3 months post-PEP (AOR = 11.3, CI: 9.0-14.2).

Conclusion and scientific significance

PEPs improve police knowledge of cannabis law. Reforms should be bundled with PEPs to improve policy implementation. (Am J Addict 2018;XX:XX-XX).
