Could a yearly dose of MDMA (or psilocybin/mescaline/LSD) ever replace the daily regiment of something like SSRIs/SNRIs to combat depression for some people? Would that be more effective with less damage? Or less effective and just as damaging? Has any study ever looked at such a thing? I’m sure it’s a very complex problem with many dimensions, I’ve just personally always been interested in this topic as an avid psychonaut with an interest in pharmacology. I’ve personally had really positive experiences from such drugs and I know that without them I would have had much worse mental health. They helped me in the same way that pharmaceuticals do for others. I’d be interested in seeing them become official parts of the pharmaceutical arsenal.

That’s the research that’s being done now. Because these substances have been illegal for decades even for research, there are still a lot of unanswered questions.
Hopefully, though. Especially since we’re getting more sure that depression doesn’t really have anything to do with serotonin and that SSRIs don’t ultimately improve overall quality of life for people with depression.

I will confirm. SSRIs did everything but improve my quality of life. In fact, all my physical issues got worse which in turn made my psychological go into silent hill mode, fog and everything.

That's a bit of a stretch in the second paragraph. It is clear that serotonin is not the beginning and end for depression, but rather is a factor in many cases. SSRIs don't help much for some people, but they do have a statistically significant improvement over placebo at helping reduce the symptoms of depression in some. Given worse depression is correlated with worse QoL generally, at least in severe cases, they can help some people. The do have nasty side effects though as well.
For myself, I'm pretty much impotent unless I stimulate myself in specific ways that don't generally apply in the case of sex.
I'm personally pretty excited about the future of depression and other mood disorder treatment past the serotonin hypothesis, and including psychedelics and other such drugs. I myself am actually legally prescribed ketamine for ketamine-assisted psychotherapy as of a few months ago.

I don't disagree with the sentiment. They are not by any metric highly successful drugs nor is the side effect profile negligible. We also can't let personal experience cloud our analysis. They are not almost worthless in data. Here's a relatively modern meta-analysis: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5889788/. They are usually on the lower end of of the spectrum of the four main classifications that most anti-depressants fall into: MAOIs, tricyclics, SSRIs and SNRIs. They also are usually on the lower end of the spectrum in terms of tolerability. Tricyclics and irreversible MAOIs are generally more effective, but also more "dirty drugs" meaning a lower specificity in action. Some irreversible MAOIs are still used as drugs of last resort in treatment resistant depression, but they are fairly dangerous comparatively.

They're definitely more side-effect & interaction heavy but a lot of providers are unduly afraid of them. The dietary restrictions are pretty overblown unless you're chowing down on artisanal cheese or chugging soy sauce. A lot of the drug interactions aren't absolute either as long as you start very low and monitor closely when going up - I was able to safely take a low dose of adderall when plenty of providers would act like being in the same room as it while on MAOIs causes instant death.

It seems, however, tat most of the role serotonin plays in depression has more to do with its relationship with glutamate than any specific function of serotonin itself.
That is to say that too much glutamate activity is linked to depression symptoms and certain serotonin receptors modulate glutamate levels in the brain. So by increasing serotonin activity, you can decrease glutamate activity and this helps with depression symptoms in some people.
tyler1128 t1_jbvfq1w wrote
NMDA antagonists are of interest, but not because of the NMDA receptor blockade. It's because of the increase in neuroplasticity they many induce, for still not well understood reasons. This is believed to be part of both ketamine and psychedelic therapy, but we really don't understand it well.
It's also worth noting that psychedelics and MDMA are also believed to work mostly through the serotonergic system, with traditional psychedelics being partial HT-2a and HT-2b agonists. MDMA is a serotonin reuptake inhibitor and releasing agent, as well as the other amphetamine effects. Serotonin is still believed to be the main cause of the empathogenic and mild hallucinogenic effects of MDMA, but it isn't an agonist or antagonist, just a re-uptake inhibitor and releasing agent. This means it floods neurons with more serotonin than usual through two separate mechanisms.
NoNumbersAtTheEnding t1_jbvn89g wrote
I don’t know why you brought up dissociatives. Those NMDA receptors - whilst yes, typically activated by glutamate, are located on GABAergic neurons, preventing the release of GABA in to the synapses.
Additionally the effects of psychedelics are more closely linked to changes in endocrine hormone distribution and GABA, glutamate and acetylcholine balance. The 5-HT2A, 2C and 1A receptor complexes which are thought to be the starting point for psychedelic effects all regulate the distribution of these compounds, along with dopamine and norepinephrine. Many do not seem to understand that inhibition of the NMDA receptor is a core mediator of effects from classical psychedelics. The activation of the 5-HT2A receptor directly prevents the activation of any NMDA receptors located on the same neuron.
It is also worth noting that SSRIs stimulate neuroplasticity and neurogenesis as well - through the same mechanism (inhibition of mTOR, mGlu2,3,7 and various cortisol functions and subsequent release of NGF and BDNF in to various brain regions).
MDMA does this as well, although the dose and frequency makes the poison. Same can be said, perhaps more surprisingly, about other amphetamines such as methamphetamine and mixed amphetamine salts. All these compounds are also capable of producing neurotoxicity as well, however this effect is only paradoxical with methamphetamine. The neurotoxicity of MDNA and things like Adderall appears to disconnected from the direct effects of the chemicals themselves (even in high doses, MDMA injected straight in to the brain does not cause toxicity - for example)
Also as of like, last month, “we don’t know how psychedelics induce this neuroplastic change” is an outdated statement. They trigger a highly novel mechanism through penetration of the cell membrane, rather than activating surface receptors. Similar to how dopamine receptors server different functions depending on their location on or within the cell, so too do serotonin receptors.
I have a lot more I want to say but I am high as balls right now. I will leave this by saying that it is unlikely that the NMDA receptor plays any role whatsoever on the antidepressant effects that have been discovered in ketamine and DXM. In fact, despite both being dissociatives with similar MoAs, it is likely the antidepressant effects are being cause by entirely different mechanisms from eachother (DXM with sigma-1 activation, ketamine has a strong link with its stimulation of adenosine release and AMPA receptor activation).
SSRIs also cause downregulation of certain serotonin receptors, namely 5-HT1A, which tends to be over active in people with anxiety and has even be speculated to play a role in the development of neural inflammation in chronic amphetamine, nicotine and alcohol abusers. It also regulates the distribution of glutamate and stress hormones like cortisol, vasopressin and epinephrine. But since having too much glutamate is linked to neural inflammation and excitoxicity, it is likely that this mechanism plays a strong role in their effects
tyler1128 t1_jbx6pvv wrote
I brought dissociatives up as I thought that was where you were talking to bringing up NMDA receptors.
You are right that all of these things affect more than just the the primary target, that being the reuptake, release, agonism/antagonism of the primary receptor target. Any drug affecting a monoamine neurotransmitter is going to have downstream effects on others, and many receptors have specific action on regulating feedback loops on the other neuorotransmitters.
I was really only speaking to the direct effect for brevity if nothing else. I'm also aware that the down-regulation of the serotonergic system over time is considered a likely part of the antidepressant mechanism of SSRIs. In general, I agree with pretty much everything you said.

Do you have any links to the studies that found a connection between serotonin and depression? Or that demonstrate long-term improvement in quality life with SSRIs?
Timely-Huckleberry73 t1_jbvgzht wrote
As far as I know all studies (certainly most studies) that have found antidepressants as “effective treatments” for depression are much shorter than the durations for which antidepressants are typically prescribed. Most studies last a few months at most. The evidence for long term effectiveness is lacking, however, there is certainly evidence of long term harm.
https://pubmed.ncbi.nlm.nih.gov/21459521/
Unfortunately there is insufficient data on long term outcomes because such studies would be expensive to conduct and the results of such studies would almost certainly be harmful to the extremely lucrative sales of antidepressants.

Ketamine treatment has done wonders for myself, and several of my friends.
tyler1128 t1_jbvtybq wrote
I never said it wasn't questionable benefit to many people, I explicitly said that. We can cite study after study or meta-analysis after meta-anaylsis, but the fact is, SSRIs score above placebo in statistical significance more often than not, opinion on them notwithstanding. I work in I guess tangent to the field of epidemiology, but I write software for use by epidemiologists for after market drug effect statistical analysis, on algorithms we use to do that. SSRIs are well above placebo, doesn't matter whether you can cite criticism of them or not, and non-SSRI antidepressants almost all work on the serotoninergic system to some level. Ketamine and bupropion are examples that don't directly, or ketamine at all, but ketamine's MOA is not fully understood beyond that we believe the neuroplasticity change to be significant. Ketamine's acute antidepressant effects last well beyond the length of the drug or known medically relevant metabolites being in your system.
Unfortunately, people who had bad experience with SSRIs really love to make that known even if they know barely beyond an iota of knowledge in the actual science. Even if this is /r/science. And it's really frustrating.

Same, I have a mixed relationship with them. Sadly ketamine therapy has not been the breakthrough for me some people have had, though it has absolutely helped.
I'm very optimistic about the future of the field of psychiatry though with the movement beyond just the stuff that has helped somewhat but has been far from a cure for the last 40 or so years.

See my comments above, they basically have proven this. I am so glad that there is a major community of people these days who are using psychedelic therapy in the ways that it should be. Massive amounts of historical context provide validity to the value of psychedelic substances when they are used as you have used them. Again, I really appreciate you pointing out that these substances don't "need" to be used in a prescriptive sense. Rather, prescriptive power should be used to help ensure the substances are given validity, as well as to ensure they are not used excessively (this abuse rarely happens as there is significant evidence to show they are not even remotely addictiveaddictive )

We're doing a lot more research in that sort of area than we have for the last 40 years, but MDMA has some potential issues for a daily regiment. Long term chronic usage of MDMA is associated with structural brain changes in both humans and animals. Whether this is the case in lower doses is not known, but it would need a good deal more study to ever get approval.
There's also the fact that most studies regarding drug harm for illicit drugs are done with people using street versions of the drug, so purity is pretty suspect, and other drugs cut in or uncleaned byproducts remaining could contribute to it as well.
CreedyBabyBoi t1_jbvkpwy wrote
Woah woah woah, at what point was daily administration of MDMA a real consideration? I am genuinely curious, because I only ever heard of MDMA as a short-term tool for use in a therapeutic setting. It seems to me that people who distort the argument for daily use of MDMA are only trying to undermine its actual therapeutic usage. Maybe I am wrong, but I have personally NEVER heard of a proposition for MDMA to be used as a daily medication. I have heard of it only to be used under a therapeutic setting, only after significant trust and connection has been made with a given patient. Again, not once have I heard that MDMA should be a daily used substance. Personally, I think that might be one of the major miscommunications which undermines the legitimacy of psychedelic therapy. I don't think any logical researcher would be considering MDMA, psilocybin, or LSD to be a daily regimen. I feel like I Can't emphasize that enough.
