I can happily say with a straight face that any and all drugs should be legal. If we brought them into legal circulation, not only could our economy profit from the presence of drugs, our government could also tax it and profit from it as well. It would also add more money to our political body indirectly by reducing the amount of taxes needed to be put towards our law enforcement and prisons, as a large portion of the crime in our country is drug related. It would remove a major source of funding from illegal operations, as no longer would it be criminal elements that held the monopoly on drugs. On top of all of that, it would also help increase social acceptance of drug problems, putting less of a stigma on admitting the presence of a problem, thus making it easier to seek help. We could start actual education on the nature and risks of drugs that isn't just mindless fear-mongering as well.
As a human being, I have no right to judge the actions of others within their own private lives if they are not infringing on my freedoms or the freedoms of others. The government should not have this right either.
