True, but an authority overreach that needs to be slapped down, doesn't justify killing an entire program.
Challenge Accepted!
There are multiple constitutional reasons that you should oppose the War on Drugs — I would go so far as to assert that one cannot be a constitutionalist and, simultaneously, support the War on Drugs.
First, let's take a look at the despicable practice of precedence *spit* — even by precedence we see that a constitutional amendment was needed to allow the federal government to regulate a particular substance: alcohol. (I despise precedence for the fact that it is functionally the judiciary plating the children's game of telephone with your legal rights and is often elevated above the Constitution itself… as we shall see.)
Second, let us investigate by what authority
they claim the power.
The commerce clause, as pertaining to interstate commerce, which reads as:
[The Congress shall have Power] To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes
The courts have held that the congress can regulate intrastate commerce via this clause because it impacts interstate commerce
. (See wickard)
Indeed, the courts have determined that non-commerce can be regulated in this manner as well. (See Raich)
[In Justice Thomas's dissent, the first paragraph claims the ruling means "the Federal Government is no longer one of limited and enumerated powers."]
Third, given the origins of the authority we clearly see that the power to regulate interstate commerce is exactly the same as the power to regulate foreign commerce. Taking this, we must consider that the actions of asserting the power to regulate inside a foreign nation exactly mirrors the regulating of commerce within a State; doing so would rightly be considered by the foreign power as a Declaration/Act of War, and the accomplishment of that assertion would involve the subjugation of that foreign nation's government — so the War on Drugs is, definitionally, the waging of war [or consequence thereof] upon the States themselves.
It does when this "authority overreach" is endemic, and has corrupted every level of our government.
Every time you read of asset forfeiture, be sure to thank a drug warrior!
