We should stop all the current Meth marketing...that'll solve the addiction problem for sure. What are all these scenarios where policy makers have absolute control of how drugs are sold and consumed? Meth is illegal, as in we don't allow "marketing" today. But if it was legal, it'll only be the marketing that will be the potential problem? What is the point of these arguments? The low enforcement/legalization options have been tried in various places in various ways, not one has gone well. Besides magical thinking, what is the actual argument that legalizing drugs makes it less of a problem?
