Datura Stramonium AKA Jimson Weed

Oh yes, very much so. Believe it or not, in the United States it's still legal to grow as a crop and a pharmacy/doctor etc can legally prescribe it. They used to use a tiny bit of it in cigarettes or an herbal mixture to smoke it to relieve asthma symptoms. Even today, the solution the optometrist uses to dilate eyes is the same compounds as Datura but mostly synthesized today. Women used to squeeze a little Datura juice in their eyes because for some reason, they thought dilated eyes were attractive.

It's not a recreational high by any means. The hallucinogenic dose is just mere milligrams essentially from a lethal dose. It's main alkaloids are Scopalamine, Hyoscyamine, and atropine. Each of these tropane alkaloids have tons of medical uses today, but using the actual plant is long outdated. Even as recent as about 30-40 years ago people would smoke these brands of herbal cigarettes with Nightshade leaves in it for asthma symptoms.
If you loaded up a pipe full of dried leaves and managed to take several puffs, you'd be in for several days, yes days, of full delirium and hallucinations. If you were a cigarette smoker, people commonly do what is called "ghost smoking," where they think they are pulling out a pack of smokes, lighting it, going through the motions of smoking it, all the while they were hallucinating even smoking in the first place. Another reason I thought to post this here is Nightshade is in the Solanaceae family, as is tobacco, eggplant, tomato, potatoes. All these plants in this family are filled with alkaloids. Nicotine in tobacco. Tomatine in tomatoes. Solanine in potatoes. Atropine, scopalamine, and hyoscamine in Nightshades of various levels. Belladonna has those same three in different levels, as does Mandrake, Angel's Trumpets, etc. Many alkaloids can stop your central nervous system. I didn't mean for it to get really technical or in depth, but I do love plants and find it all very fascinating. Even things that may be toxic, such as nicotine, our bodies have been adapted to for thousands if not hundreds of thousands of years. We have nicotine receptors. We have receptors for all the plants. We actually hallucinate our very own reality as each of us see it. Things like optical illusions go to show how our consciousness predicts what it thinks it should be seeing and experiencing, and in effect, it's a very long technical explanation but we each create our own hallucinated realm space and reality. People with mental imbalances see completely distorted realities from what a mentally healthy individual sees. Like say someone with a dissociative personality disorder. They cannot visualize themselves as being real and they constantly feel like they are dreaming and watching their own life. This is much of the reasoning behind shamans and people experimenting with drugs to alter their own state of consciousness. It's very interesting stuff because Google and companies creating Artificial Intelligence at this very moment are training the machines on all kinds of substances. It's unreal. They are training the AI's on LSD to teach them empathy. Training them on alcohol, and nicotine, and other hallucinogenic effects as well. Google engineers have said they must train Artificial Intelligence on LSD algorithms to teach empathy and to value human life. Totally different topic, but it all comes back to these plants that we use on this planet we all inhabit.

In other words, it's like SG 1792?

When I was in high school, a friend of mine ate an unknown quantity of the seeds and was hospitalized in a mental hospital for many days. When he got out, he said he could never get high again - no weed, no alcohol, etc. I asked him what it was like and he said it was like nightmares that you couldn't wake up from. Said he saw things like elephants bursting through his bedroom walls. I haven't seen him in all these years and don't know what the long-term ramifications were.

Morning glory seeds also have the same effect if consumed..the bad trip that is..
