The relationship between the regulation of licit medications containing pseudoephedrine and the illicit methamphetamine market in Czechia and neighbouring countries

A systematic review of actors, actions, and outcomes of community-based efforts to prevent or reduce methamphetamine use

Background

There has been an increase in methamphetamine use across the globe, despite widespread control of the drug, prevention, and treatment. Community-based approaches have proven effective in tackling diverse health-related challenges including substance use; however, little is known regarding community programs targeting methamphetamine use. We conducted a systematic literature review on community programs aimed at tackling the use of methamphetamine across the globe.

Method

Relevant literature from peer-reviewed and gray literature sources were systematically identified. A grid template was used to extract and synthesize findings from retrieved literature regarding themes of actors, actions, and outcomes related to identified programs.

Results

A total of 19 documents met our inclusion criteria. Some of the dominant actors in efforts to reduce methamphetamine use in communities were local councils, drug enforcement units, influential persons in the community, people who use or had used methamphetamine, business corporations, and already-existing health promoting platforms. Actions taken were typically education/awareness/information campaigns. Drug enforcement agencies appeared to make little gains when acting alone, and appeared to drive dealers and users underground. Many of the efforts made at the community level were alluded to be beneficial; however, it was difficult to quantify the impact of programs. Community-level efforts also tended to cascade to other drugs.

Conclusion

Community-based actors and actions are diverse and critical to the prevention of methamphetamine use. There is a need to better coordinate and integrate different actors and interventions so that outcomes can be better monitored and evaluated for greater effectiveness in reducing methamphetamine use.

The Identification of Precursor Regulation Impact on the Methamphetamine Market and Public Health Indicators in the Czech Republic: Time Series Structural Break Analysis

BACKGROUND

This study provides insight into the impact of methamphetamine precursor regulation, which is considered to be one of the most important tools of supply reduction and a tool with potential public health impact.

METHODS

It is based on a longitudinal and quasi-experimental design and it investigates the changes of methamphetamine precursor regulation in Czech Republic, which is treated as a natural experiment. The statistical analysis uses features from the generalized fluctuation test framework as well as from the F test framework to estimate structural changes in the methamphetamine-related arrests and nonfatal intoxications time series.

RESULTS

The analysis identified structural breaks in the majority of the methamphetamine drug market-related time series in the period related to the tightening of regulation. The results of this study show that methamphetamine precursor regulation was associated with the proliferation of international and organized crime groups and with no change in the overall number of arrests and nonfatal intoxications.

CONCLUSIONS

The precursor regulation ceteris paribus plausibly leads to the change in drug supply towards more organized groups and to an increasing involvement of foreign nationals at the drug market and is not effective in suppressing the methamphetamine market and in reducing the public health indicator of nonfatal methamphetamine intoxications.
