It's because they're illegal that their growing, processing & delivering wreaks so much harm. Just like with alcohol prohibition. They're illegal, yet in high demand, therefore a black market will rise to meet the demand, minus any regulation, monitoring, standardization, unionisation, etc etc. If they were legal, society-controlled organizations that are bound to follow laws would take the place of the lawless international drug kingpins & everyone they subjugate, thoroughly use, then discard.i believe cocaine is one of three drugs which should remain illegal and come with ways to help users with a addiction to it. Its literally funding terrorism in south america and central america everytime somebody uses cocaine they are support barbaic blood cartels who are x100 worse than even isis. Ecstasy should be legal though.
