The government can't even control the borders how will they control legal drugs and the people who use them. Legalizing drugs will only weaken America to hostile take over by rouge nations. Perhaps that's why some do want to legalize drugs.
I don't recall any rouge nations taking over the US the last time a major drug prohibition was repealed.
How will legalizing drugs subject America to takeover by rouge nations, and which rouge nations are going to take us over?
