Statement

You know someone who drinks. You know what it does to them.

You have watched it happen — the slow contraction of their possibility space, the coupling pathways that close one by one, the version of themselves that gets smaller with every glass.

You have watched this, and you have watched it be legal.

You may also know someone who uses cannabis. You have watched them face prosecution, job loss, or imprisonment for something that has never killed anyone.

You have watched this, and you have been told it is justice.

This paper makes one structural argument with two parts. First: the classification of substances into “legal” and “illegal” bears no relationship to their measured stabilising or destabilising effects.

The legal status is inverted with respect to the structural consequence. Second: the category “drug” is applied indiscriminately to substances with fundamentally different structural profiles — a classification error so severe it prevents coherent policy.

The strongest structural argument for alcohol’s current legal status: prohibition was attempted (US, 1920–1933) and produced catastrophic destabilisation — organised crime, black markets, poisoning from unregulated production, loss of tax revenue, criminalisation of a majority-participating population.

The axioms agree: the correction for alcohol is Level 2 (restriction), not Level 3 (prohibition). The failure of alcohol prohibition does not justify cannabis prohibition.

It demonstrates that prohibition itself is a destabilising correction when applied to a widely-used substance. The lesson applies to cannabis and psilocybin equally.
