Developing policies to prevent, manage, and treat substance dependence is complex, with different stakeholders having varying priorities and perspectives that often conflict.
This complexity can lead to a simplistic solution: "Just get rid of the substances!" However, this approach often results in heavy regulation, criminalization, and/or prohibition.
Consider the example of alcohol prohibition in the early 1900s, which initially led to a significant decrease in use, but consumption quickly rose again before stabilizing at a level somewhat lower than before Prohibition.
Consumption remained roughly at this level even after the 21st Amendment reversed the ban.
The question remains: is prohibition the best solution? The answer is not straightforward, and instead, raises another question: "Succeed at what?"
Author's summary: Prohibition may not be the best solution to substance use complexity.
