The Economics of Cannabis Decriminalization: What Different Policy Models Cost | Research

The takeaway

An economic analysis found that repressive cannabis policies are expensive without reducing use, while legalization with regulated pricing could reduce enforcement costs, generate tax revenue, and avoid a consumption spike.

Read this if you are interested in the economic arguments around cannabis legalization and how different policy models compare.

Countries with repressive policies do not have lower cannabis use rates

What the researchers found

This economic review compared cannabis policy models from around the world, from full prohibition to consumption tolerance (Netherlands) to legalized markets (Uruguay, U.S. states).

The central finding was that repressive cannabis policies are costly and have limited impact on prevalence. Countries with strict enforcement do not have lower cannabis use rates than those with tolerant laws.

Legalizing consumption significantly reduces enforcement costs. Full legalization of supply and consumption reduces costs further while creating employment and generating tax revenue. The review argued that legalization would not cause a sudden consumption spike, provided the government sets taxes to keep the product at its current street price.

The key risks identified were earlier initiation age and increased consumption if prices drop too low.

Why it matters

This analysis reframes the cannabis policy debate from a moral question to an economic one: which approach minimizes total social costs while achieving public health goals? The data suggest prohibition is the most expensive option with uncertain benefits.

The numbers in context

Models compared: prohibition, decriminalization, consumption tolerance (Netherlands), full legalization (U.S. states, Uruguay); key variable: price regulation to prevent consumption increases

How the study worked

Economic review of international literature on cannabis legislative models. Analyzed policy scenarios using fundamental market economy concepts, comparing costs and benefits of each approach.

What this study cannot tell us

Economic modeling relies on assumptions about consumer behavior. International comparisons may not account for cultural differences. Long-term effects of legalization were not fully available at the time of publication.

How to read the evidence

Economic review synthesizing international policy evidence. Provides theoretical framework but cannot predict outcomes of policy changes with certainty.

When this study was published

Published in 2015. Multiple U.S. states and countries have since legalized, providing real-world data on these economic predictions.

The bigger picture

The economic argument for legalization rests on redirecting enforcement savings toward prevention and education. However, price regulation is critical: if legal cannabis becomes cheaper than street cannabis, consumption could rise.

Questions still open

What is the optimal tax rate to prevent consumption increases while undercutting the black market? How should tax revenues be allocated between prevention, treatment, and general revenue? Do consumption increases after legalization stabilize over time?

Common questions

Does legalization increase cannabis use?

This analysis argued that legalization would not cause a sudden spike in consumption if prices are kept stable through taxation. However, if legal cannabis becomes cheaper, consumption could rise. Price regulation was identified as the critical variable.

Where does the money go from cannabis taxes?

The review suggested that savings from reduced enforcement plus new tax revenue could fund prevention, education, and treatment programs. How this revenue is actually allocated varies by jurisdiction.
