We are currently going after drug cartels as Trump announced the other day.
They can break up all the drug lines and all the cartels they want - if they don't legalize drugs they will all just come right back & rebuild. They are the deep state's biggest cash money source.
Legalizing everything would not only provide us with a brand new multi-billion dollar industry, but put the smugglers & cartels out of business and cut off that deep state funding source permanently.
Overall drug use will actually decline and instead of pissing away how many billions of dollars on the bullshit war on drugs, put that money into rehab for the ones who are addicted to the hard stuff.
