Border agents keep finding drugs hidden in food shipments — here are some of smugglers' most bizarre methods
Just legalize it. I would prefer to only legalize the use of prescription drugs, and perhaps a few others like marijuana. Create an over the counter recreational drug exception, and allow these drugs to be sold over the counter but with strict liability limits, meaning that unless the drug was adulterated, or the wrong drug sold, there would be no legal recourse.
Then use the tens of billions of dollars saved in law enforcement, corrections, border, and other federal, and state agencies to provide substantial aid to drug users who wish to quit.
I do not know if the problem is the fact that US murder/violent crime rates would decline by 70%, or border incursions would all but stop except for illegal workers seeking entry. But as it is this is an absurdly bad, failed policy. End it now, treat the problem as a medical problem, and treat all residual criminality as crime, and we will be in a much better place.
Or we can continue to spend billions in ways that allow the politicians lots of opportunities for graft, and corruption.
