The primary purpose of the controlled substance laws is to grant a health-care monopoly to the federal government and it's agents. If you ever get cancer you will belatedly discover that you have no freedom when it comes to your treatment. You are channelled into barbaric, government-approved treatments, even though most of the cures are as bad as the disease. And someday you won't even be able to buy an aspirin without a prescription. Or a can of aerosol paint, because some suicidal numbskulls insist on abusing it.
I hope you enjoy being a slave to the government's health care system, and I especially hope you enjoy it as more and more of your paycheck goes to subsidize it.
