Effects of Drug Decriminalization
Introduction to Drug Decriminalization
Drug decriminalization refers to the removal of criminal penalties for the possession and personal use of certain drugs, shifting the focus from a criminal justice approach to a public health perspective. This policy change aims to reduce the negative consequences associated with drug use and criminalization, such as incarceration and social stigma, while promoting harm reduction and treatment.
Impact on Drug Use and Availability
Prevalence and Frequency of Use
Research indicates that decriminalization does not significantly impact the prevalence or frequency of drug use. Studies have shown that the rates of drug use, including marijuana, did not increase significantly in regions where decriminalization policies were implemented1 2 4 5. For instance, in the United States, states that decriminalized marijuana did not see a substantial rise in usage compared to those that maintained stricter penalties4.
Drug Prices and Availability
Decriminalization has not led to a decrease in drug prices, nor has it significantly altered the availability of drugs. The systematic review of literature from 2016 to 2017 found no evidence that drug prices decreased following decriminalization1. This suggests that the market dynamics of drug supply and demand remain relatively unaffected by changes in legal status.
Health and Social Outcomes
Public Health Approach
Shifting from criminal sanctions to a public health approach is a key recommendation from policy-based studies on decriminalization. This approach is endorsed by the United Nations, which views drug addiction as a preventable and treatable health disorder1. Countries that have adopted this model, such as Portugal, have seen positive outcomes in terms of reduced drug-related deaths and improved public health metrics8 9.
Mental and Physical Health
The decriminalization of drugs, particularly marijuana, has been associated with mixed health outcomes. While some studies report an increase in negative mental health impacts, such as psychosis and suicidal behaviors among users, others highlight the potential for reduced harm through better access to health services and harm reduction programs6 9. For example, Portugal's decriminalization policy led to a decrease in drug-related deaths in the short term, although long-term impacts were negligible8.
Overdose Deaths
One concerning finding is the potential increase in drug overdose deaths following decriminalization without substantial public health investments. In Oregon, the decriminalization of small amounts of drugs in 2021 resulted in a significant rise in overdose deaths, highlighting the need for comprehensive public health strategies to accompany decriminalization efforts10.
Economic and Social Impacts
Criminal Justice System Savings
Decriminalization has led to substantial savings in the criminal justice system by reducing the number of drug-related arrests and incarcerations. This shift allows resources to be reallocated towards more effective public health interventions and harm reduction programs4.
Crime and Violence
The impact of decriminalization on crime and violence is complex. While some studies suggest that decriminalization can reduce the health damage from crime by lowering the rates of drug-related violence, others indicate that it may lead to an increase in certain types of crime, such as homicides, as drug trafficking organizations adjust to the new legal landscape8 9.
Conclusion
The effects of drug decriminalization are multifaceted, with both positive and negative outcomes. While decriminalization can lead to significant savings in the criminal justice system and support a public health approach to drug addiction, it does not necessarily reduce drug use or prices. Health outcomes are mixed, with potential increases in mental health issues and overdose deaths if not accompanied by adequate public health investments. Overall, the success of decriminalization policies depends on comprehensive strategies that include harm reduction, treatment, and robust public health support.

Criminalization reduces drug use through restricted availability, increased prices, and the risk of punishment, but a more realistic perspective acknowledges limitations in human rationality and the importance of moral reasoning and informal social control factors.
