A big part of depression is negative thinking, so it's not too much of a stretch to believe that positive thoughts, like hope, would lessen depression.

In a late-stage capitalism world, where the climate is collapsing, and homes are unaffordable, where does hope come from?

Hope comes from negative situations, you hope things will get better. There wouldn't be any reason for hope if everything was going well.

Of course, hoping for change and actually changing yourself are two very different things.

Beyond the importance of controlling the placebo effect, I am worried that a lot of the drug-depression research is overlooking an important possibility: that the thing about ketamine/psilocybin/etc that is helping with depression is not some latent property of the molecule, but rather the actual transcendent experience of the trip. In other words, the trip is the point, not the mechanistic neuro-tinkering [0]. Impor…

If qualia are not different that our “neurological machinery” (and all available evidence shows this so far, not least the incoherence of definitions of qualia that try to exclude such) then medicine is already considering such as a major parameter. If they are different (and exist at all) then such needs to be demonstrated before they can be reliably considered. Given even proponents of qualia can’t reliably agree w…

Ketamine dosed at levels used in a lot of the original depression studies won’t result in anything resembling a “trip”. Many of the more responsible clinics will carefully administer IV ketamine infusions over 40 minute (IIRC) spans at levels that only result in a little dizziness.

The association between ketamine depression therapy and “tripping” is a more recent development, pushed partially by clinics and influencers seizing on the trend in the most dramatic way possible. Some of the clinics will now dose people with excessively high doses with the goal of inducing trips and overt experiences, even though this isn’t supported by the literature.

I’m actually growing concerned that the pop-culture obsession with tripping and the over zealousness of ketamine providers is going to result in regulatory crackdown on the whole process.

A few months ago I was discussing the topic with a psychiatrist friend. She had tried prescribing ketamine for several patients, optimistically. However, a number of them complained that it wasn’t enough because they weren’t having full on hallucinations like they had read about online or in books. Several of them also started trying to demand higher and very early refills, despite her explaining up front that she was only willing to follow the dosing protocols used in studies.

Ketamine treatment is something I've seriously considered for my depression. It's hard not to be lured in by all the miraculous claims by folks who have been down the same path and found relief. I've been through the rounds with traditional ADHD and depression treatment with side effects that rival the underlying symptoms and have tried a few different prescriptions. I'm just so tired. Doing simple things like paying your electric bill or getting out of bed when you don't have external demands shouldn't be so damn hard.

Earlier quoted context omitted.

Many psychedelic-era personas expressed this sentiment as well: you don't need psychedelic drugs to reach that state, you could also spend 10 years practicing meditation daily. This view ignores the major application of these substances. Ketamine-induced self-therapy is accessible instantly and acts as a major reset. When you are experiencing long-term depression and/or anxiety, the advice to "just meditate" or do de…

I just want to endorse this comment. Psychadelic drugs have a miraculous property: they elicit transcendent states reliably . Eat the mushroom and you will experience it. There are corresponding risks to this, of course, but that's the flip side of their utility as a (sharp) tool.

these tools allow exploration of not just introspection but also states that otherwise belong safely behind a closed door.

Yes I might actually enjoy having countless shards of the universe's ideas slicing through my ego for a few hours at night over the weekend; no I never want that to experience that during a workday.

Agree. I have heard stories of people who “had one treatment and never smoked/put their elbows on the dinner table ever again.” My experiences seemed to benefit more from watching David Attenborough and feeling a connection to life. I’d interpret the dad of a family of mountain lions as an analogue of my dad, etc. Seeing events as taking place in a dissociated context. All that introspection is what I found useful ab…

Social media selection bias at play. The real world results are very mixed, but usually don’t result in life changing benefits that you read about in selected stories.

There’s also an unhelpful bias toward purely positive stories on the internet. I had a friend get addicted (yes, addicted) to psychedelics who could not stop acquiring and dosing them on a weekly basis for years. It was a huge problem, but strangely when I mention this story people will rush to argue it, deny it, insist I’m lying, or try to downplay it with the old “psychological addiction isn’t physical addiction” gimmick.

I'm more interested in the effects of Ketamine on anxiety. I know that it's not as effective, but haven't seen any statistics specifically related to anxiety. I have gotten my Ketamine through Mindbloom, and just need to schedule my treatment and follow up dates. My depression effects are due to my suffering through anxiety for over 20 years (started in 1999). My anxiety also seemed to correlate with 2 bad trips from…

How does Mindbloom program work? From their website, it appears they send Ketamine pills. How different is the experience from IV administered doses?

Alternative explanation: ketamine isn’t better than placebo for treating depression when given to someone who’s under anesthesia. You have to be awake.

Similarly, I bet that if you gave psilocybin to someone under anesthesia, they wouldn’t get the same benefits as someone who took it while awake.

I am a materialist. I agree delusions are powerful mechanism against depression, but most of them, like religion, have awful side effects.

This is not the first trial of ketamine used under clinical anaesthesia to disguise its effects. A previous study using similar methods in 2018 found the usual effects of surgery: a transient increase in depressive symptoms. I'm no expert but my inclination is to blame this on postoperative pain. https://www.sciencedirect.com/science/article/pii/S000709121... The confidence interval in the new study includes zero, al…

Ketamine IV or compound medication without any other drugs is so profoundly different from Ketamine as part of a procedure where you’re otherwise unconscious. Just no comparison.

Could you explain? What is the difference? I only had Ketamine once during surgery and I vividly remember the few hours after.
