What Happens After 550 Times the Usual Dose of LSD? (cnn.com) 91

"From the Journal of Studies on Alcohol and Drugs comes three case studies on people who benefited from LSD overdoses including one woman who took a dose of 55 milligrams of pure powdered LSD," writes clovis (Slashdot reader #4,684).

CNN reports: The 49-year-old woman, known as CB, had contracted Lyme disease in her early 20s, which damaged her feet and ankles and left her in "significant pain." In September 2015, she took 55 milligrams of what she believed was cocaine but was actually "pure LSD in powder form." The authors defined a normal recreational dose as 100 micrograms -- equal to 0.1 milligrams. The woman blacked out and vomited frequently for the next 12 hours but reported feeling "pleasantly high" for the 12 hours after that -- still vomiting, but less often. According to her roommate, she sat mostly still in a chair, either with her eyes open or rolled back, occasionally speaking random words. Ten hours later, she was able to hold a conversation and "seemed coherent."

Her foot pain was gone the next day and she stopped using morphine for five days. While the pain returned, she was able to control it with a lower dose of morphine and a microdose of LSD every three days. After more than two years, in January 2018, she stopped using both morphine and LSD and reported no withdrawal symptoms, although the case report said she did experience an increase in anxiety, depression and social withdrawal.

      I wouldn't take the "estimated lethal dose" too seriously, as I don't think it's ever been validated. This case, if accurate, would seem to prove that it was seriously lowballed.

      • Maybe.

          But not likely. d-LSD stimulates the release of serotonin while also inhibiting the re-uptake of serotonin from the synapse. The stimulation and re-uptake inhibition are dosage dependent. About 5 milligrams causes the maximum effect. Beyond this dosage, there is no effect. Serotonin depletion will occur in 6 to 12 hours independent of dosage. After depletion it takes several days for sufficient reserves to be synthesized by the body for a subsequent dose (of any size) of d-LSD to have any effect whats

      The CIA has a tendency to ignore peer review as well as pay experts to lie.

    • Timothy Leary, a psychologist who attained cult-like popularity in the 1960's, strongly advocated psychedelic drugs. His work lacked scientific rigor: the LSD available was often "kitchen chemistry" quality. I'll admit that my college dormitory had issues with people making and selling it. I did know someone who died from LSD, but the death involved involved going swimming at a party with people too stoned to stop them.

      Leary and his colleague, Professor Alpert, were fired for many reasons, including not sh

      • In the 1980s he was saying that with computers and VR you will no longer need to take drugs to choose your own experience, you'll be able to select one with more precision.

        He also warned strongly about the need to control the content of screens that you look at. In a way he's sort a spiritual guide for me, but not in the ways that people normally think of him; in my practice at ad-blocking, and limiting passive video consumption.

      First of all, a 100 ug dose is insufficient for a psychedelic experience. It'll get you high, yes, but you'll get some mild colorization of white surfaces and a little shifting of textured surfaces, at most. However, you won't get anything close to the full ride, à la the Harvard elites at Timothy Leary's Milford, Connecticutt farm or Ken Kesey's Merry Pranksters and their Acid Tests. For that, you need a minimum of 300-400 ug.

      I don't do acid any more, but, back in the day, I took as much as 1250 ug of high-purity LSD in a single yellow microdot. Believe me when I tell you that 100 ug isn't even in the same universe as THAT experience.

        LSD already works in the 1Âg to 2Âg range. The actual dose is close to irrelevant for going "onto a trip".

        There is no known lethal dose for it, I assume you could die if you eat a pound of it as powder and your digestic system can not handle it. But I also assume if the dose gets into the grams range, you never return from your trip ...

        considering its simply a trigger compound for your brain to release another chemical, I doubt there really can be a lethal dose.

        Interesting point, but I have one question -- "Harvard elites". What does that mean? Were they Harvard students? Professors? The Dean of Humanities? Faculty? Administration? Alumni? What do we learn by your calling them "elites" -- that you disdain them? Why is that interesting and how does it contribute to your point?

      thats not how LSD works. LSD is a trigger compound for your brain to release another chemical that then induces the effects. Thats why you cannot trip two days in a row. You have already used up everything and have to rebuild the supply. There is a book written quite a long time ago by Timothy Leary that talked about quite a bit of this. I really don't think there is a lethal dose. I think beyond a specific dose, its all just wasted.

        That is very far from the truth. The majority of its effects come from serotonin (5-HT) agonism, not neurotransmitter release.

        "LSD acts as a 5âHT autoreceptor agonist on 5âHT1A receptors in the LC, the RN, and the cortex. It inhibits firing and serotonin release of these cells. It also acts as a partial agonist on the postsynaptic 5âHT1A site. LSD has high affinity for other 5âHT1 subtypes 5âHT1B, 5âHT1D, and 5âHT1E. Effects of LSD on 5

It's basically a given that it was mixed with something reasonably inactive like starch or powdered sugar to make it much, much easier to measure. With the middle of the effectiveness curve being somewhere between 100 and 250 micrograms (roughly between two and five grains of sand--no joke) it needs

      There is record of a lethal dose of LSD. It was administered to a female elephant in a bizarre attempt to induce rut. I don't recall the g per Kg of body mass, but it was rather high as I recall. The elephant appeared fine for a while and then keeled over dead according to the account I read in what I recall was a chemistry journal back in the seventies. The article could have been published in the sixties. I haven't man

    • by yarbo ( 626329 )
      Lethal doses can refer to LD1 (the amount that would kill 1%), LD50 (the amount that would kill 50%) or many other measures. They do not administer this to 100 humans until 50 people die, they extrapolate this from animal models and then attempt to scale it. I would not take the dose and tempt fate, but this in no way suggests that someone couldn't live through the experience.
  • It's hilarious how apologetic the article is. After every line you can almost hear the chant "But it's still bayted MmmmmmKaaaaay!" as if sweatles were breaking out on the author's forehead wondering if she should secure wipe TFA and just write that now they have 3 eyes and think they're a giant glass of orange juice.

        Since unlike LSD, cyanide has been known to kill people it wouldn't have been as funny. but I might have found the warnings excessive

        Of course there would also be more astonishment since also unlike LSD, cyanide has never shown signs that it might have beneficial effects on anyone.

    The summary omits important details: Some time after the incident, due to increasingly erratic behavior, she was kicked out of Pink Floyd. Her subsequent abortive solo career was soon abandoned. Since then, she has been living in seclusion outside the city, supported by the royalty checks she still regularly receives.

    • Voted funny, however in reality, the story was that they noticed LSD's effects were *similar* to schizophrenia symptoms, so the theory came about that LSD cause schizophrenia. They never actually got around to proving any connection.

      The only connections we have are observational: Guy X took LSD then was diagnosed with schizophrenia. This is about as convincing as the thing with immunizations and autism. Schizophrenia usually onsets from late teens to early 20s. Drug experimentation also peaks around late te

      A lot of medical journals have a section for case studies. It's a place where doctors submit weird things they see, in case anyone else sees something similar. To raise the awareness of the community that something interesting might (or probably not) be going on here.

      I would expect such reports to be especially important in the drug research field, since double-blind studies are illegal and often unethical.
