Here is an article about the background history of psychedelics . From the article “https://www.beckleyfoundation.org/psychedelic-research-timeline-2/ . 
“After a long winter, spring has come for psychedelic research. In 1943, Albert Hoffman was only just discovering the psychoactive properties of LSD and it would be another ten years before R. Gordon Wasson set off to gather strains of psilocybin in the mountains of Mexico. It was the 1950s, 60s, and 70s that were to be the most fruitful decades of the 20th century for psychedelic research. Thousands of LSD studies were carried out, as researchers looked into its potential as a tool for psychotherapy and its effects on everything from metabolism, to time perception, to its potency as a tool for combatting addiction. As the sun set on the 60s, the US government ramped up its war on drugs and in 1970 President Nixon introduced the Controlled Substances Act, rendering psilocybin, mescaline, LSD and DMT illegal. The act effectively ended all government-sanctioned psychedelic research, and what was a flood diminished to a trickle, which was how it would stay for the following three decades.”

This is what I have to say on this matter :

There is scientific proof that PSYCHEDELICS HELP CURE CANCER , TUMORS , DEPRESSION , ANXIETY , ALCOHOLISM, AND ALZHEIMERS. It is obvious that the pharmaceutical companies ran by the United States of America’s government is greedy . Angry and greedy when we can be keeping people alive and healthy . People are happier with mushrooms . The mushroom mycelium aligns with the human brain so we need it. Psychedelics  especially Psilocybin mushrooms help increase the neurons in the human brain making humans more intelligent and it stops Alzheimer’s. The government has brain washed the world with lies and unscientific proof since the late 60s - 90s making people believe that mushrooms were drugs . They said that it was drugs BECAUSE people weren’t miserable. It was an eye opener . We need to legalize mushrooms and all psychedelics to save us from being extinct in this horrible disgusting controlled environment that we live in today.

Psilocybin Mushrooms also cure pain , and it also makes the human body and brain reach a spiritual level that we all need to experience in our life . It literally helps our moods and how we view others . It is obvious that the government has control over us humans and we are here on a free planet . We are supposed to embrace nature and have these psychedelic experiences. We also deserve to eat the things grown on this earth to cure us and help us fix these problems. It only takes 3 psilocybin pills for a proper treatment in the medical procedure. It is obvious that it is banned because the pharmacy won’t get as much money so they are giving up these bad medications and all chemical made drugs so the insurance we have would pay more for it . We need to legalize psychedelics for our own sake .
