Yeah, prohibition is a terrible policy for everyone except the cops, jailers (including private, for-profit jailers), government spooks, smugglers, arms dealers, hitmen, chain and shackle manufacturers, etc. who make a living from it. I'm taxed to pay some of the world's most odious people to stop a small percentage of the supply of these drugs. Meanwhile, the vast majority of the supply makes it through and causes untold suffering for addicts, often thanks to other (or the same) taxpayer-funded bad guys and an onramp provided by the legal pharmaceutical industry. In the impoverished countries where the supply comes from, all this revenue funds hellish slave/feudal economies where a small violent elite terrorize, torture, and kill working people. Even in the developed world, addicts are weaponized by others for all kinds of violence (drug gangs, human trafficking rings, etc.) and net-negative property crime (stripping copper from abandoned houses, stealing catalytic converters, etc.).

In short, banning hard drugs is very very obviously a losing policy that serves only to enrich the world's worst people at the expense of everyone else.
