The use of laughing gas changed William James' ideas about the very nature of reality. To outlaw such substances is to outlaw human advancement. 
In an article about Mazatec mushroom use, the author says: "Mushrooms should not be considered a drug." True. But then NOTHING should be considered a drug: every substance has potential good uses.
Getting off antidepressants can make things worse for only one reason: because we have outlawed all the drugs that could help with the transition. Right now, getting off any drug basically means becoming a drug-free Christian Scientist. No wonder withdrawal is hard.
People talk about how dangerous Jamaica is -- but no one reminds us that it is all due to America's Drug War. Yes, cannabis and psilocybin are legal there, but plenty of drugs are not, and even if they were, their illegality elsewhere would lead to fierce dealer rivalry.
Materialist scientists are drug war collaborators. They are more than happy to have their fight against idealism rigged by drug law, which outlaws precisely those substances whose use serves to cast their materialism into question.
Here's one problem that supporters of the psychiatric pill mill never address: the fact that Big Pharma antidepressants demoralize users by turning them into patients for life.
The sick thing is that the DEA is still saying that psilocybin has no medical uses and is addictive. They should be put on trial for crimes against humanity for using such lies to keep people from using the gifts of Mother Nature.
Americans believe scientists when they say that drugs like MDMA are not proven effective. That's false. They are super effective and obviously so. It's just that science holds entheogenic medicines to the standards of reductive materialism. That's unfair and inappropriate.
When is the Holocaust Museum going to recognize that the Drug War has Nazified American life? Probably, on the same day that the Jefferson Foundation finally admits to having sold out Jefferson by inviting the DEA onto his estate in 1987 to confiscate his poppy plants.
Outlawing drugs is outlawing obvious therapies for Alzheimer's and autism patients, therapies based on common sense and not on the passion-free behaviorism of modern scientists.
All drugs have potential positive uses for somebody, at some dose, in some circumstance, alone or in combination. To decide in advance that a drug is completely useless is an offense to reason and to human liberty.
