The Law of the Earth guarantees the Right to Freedom of Mind: to cultivate any mental, emotional, or spiritual state, including by ingesting any mind-altering substance, as long as one does nothing that endangers others. It also guarantees the Right to Freedom of Medicine, including growing and sharing any plant or herb.
No force may be used against anyone who isn't harming anyone. (Legitimate Force.) The "war on drugs" fails that test, and it's on the list of irrational rules the Take Back Your Rights Plan works to remove.
The Law also ends punishment. Prisons, cages, and shackles are contraband. A person who is genuinely dangerous is held in a Custodial Village near home, in warm and humane conditions, only until they understand what they did wrong and are no longer a danger. (Title 5: Grace.)
And the timing isn't a coincidence. The rise of private prisons, militarized police, and the drug war tracks the rise of factory farming. As people came to abuse those under their power, the powerful came to abuse the people. (On the Importance of Animal Rights.)
