FinCEN warns that illicit e-cigarettes are being used in fentanyl-related money laundering schemes, highlighting the predictable failure of prohibitionist policies in the US vaping market. The article argues that the CDC and FDA's suppression of regulated vaping products, through bans and frozen approvals, has not eliminated demand but forced it underground. This has empowered criminal organizations to establish a parallel national supply chain for unregulated products, mirroring historical failures of alcohol and drug prohibition. These illicit products are of unknown origin, lack safety standards, and pose significant health risks to consumers. The author criticizes current enforcement as "regulatory theater," stating that policymakers are complicit in creating this dangerous environment, enriching criminals, and jeopardizing public health by removing lawful alternatives. The harms that emerge are direct, engineered consequences of abandoning effective regulation for prohibition.
