Another huge problem is people rarely accept the realities on the ground in these abstract debates. That people will continue to smoke cigarettes otherwise or find black market means to vape even when its heavily regulated or banned. As a consequence it simply pushes people into completely unsafe vendors and shady people, pushing good kids into the justice system, encouraging related criminal activity which black markets help finance, etc creating a net-worse situation.

High school kids have been able to find weed for decades despite various stringent laws. Many drug dealers are high school kids themselves. I wouldn't be surprised to find kids selling vape oil and cheap chinese vape pens.

This should ultimately be about balancing real alternatives, doing our best to minimize harm, and educating the people who will do it anyway. Although most education attempts have laughably failed like those 90s TV spots by out of touch ad companies paid for by the gov.

People like to argue in some fantasy idealistic world where people will stop engaging in non-violent activity which harms themselves because policy makers say so.
