Restrictive Deterrence in Drug Offenses: A Systematic Review and Meta-Synthesis of Mixed Studies.

Deterrence by punishment aims to prevent a crime; however, it is not always successful. Restrictive deterrence explains the continuous criminal activities that occur despite deterrence; offenders enact various strategies to avoid detection, which is more typical among drug offenders given that they have a high frequency of offending and exposure to punishment. This systematic review provides an in-depth understanding of restrictive deterrence of drug offenders. Two prominent themes, "restrictive deterrence strategy" and "deterrability and restrictive deterrence," depict drug offenders' restrictive deterrence and effectively fit within the certainty-severity framework of punishment. Future studies should investigate restrictive deterrence strategies in the after-arrest context, the facilitative effect of perception of risk on strategy development, and facilitators or inhibitors affecting the diffusion of restrictive deterrence strategies.
