I think you make some interesting points, and it's a very well thought-out post, but this is the definition of "poisoning the well". You're attempting to preemptively discredit the most obvious flaw in your argument.
There is a massive amount of evidence for the impact on both society, economy and neurology for each of the drugs listed in your last paragraph – and it's these impacts that often change personal and societal perception of risk and reward. Caffeine, at average doses, induces an effect that is comparable to a small cortisol spike – it is mildly addictive, but nowhere near that of an opioid, for example.
Drugs like meth and heroine (and one wonders why you left off fentanyl) are highly addictive and destructive, cause enormous loss of life an an inconceivable scale, and can permanently damage neurological pathways. From what I've read, the impact of hallucinogenics is less well understood... but probably not great.
If your argument is "we like to say caffeine and alcohol are fine, when they're really no different than opioids and meth", well there _is_ a staggeringly enormous difference in the potency and impact of caffeine vs the other drugs you've listed. I do agree with you that alcohol is far more harmful than society cares to admit, however, and that's both well-studied and often ignored.
The point is caffeine etc. corrupt the mind and cause a person's mental faculties to run in a way they were not initially designed to.
The point is not that these drugs are all extremely harmful, only that they are all harmful. Caffeine and other things get a pass because the "hard drugs" are so uniquely and visibly harmful that they overshadow all other forms of harm.
One could even say that this has tricked us into thinking that lesser drugs like caffeine or canabinoids are "effectively harmless" because they're not causing us to OD or steal things to get another hit or causing visibly psychotic states. But that is not true. We've simply accepted that the harm they due is not worth thinking about (this is subjective, not objective).
Not everyone is the same, there is a lot of variety, what you say could indeed be true for most people but can also not be true for a small minority of people.
What is the Autosomal dominant disordered gene polymorphism you have that causes your mental illness? I am assuming you are just guessing here?
> I have to take psychopharmacological drugs just to get close to normal.
I hope you can consider that you are taking drugs to manage being in an environment/diet that you are not genetically adapted to.
I used to think like you, but then I saw my genetics, now after 35 years, I am on no meds and have essentially cured my schizoaffective disorder.
I tried the no-drugs and being super healthy approach for the vast majority of my life, I look like a pro-athlete, the only reason I started the meds was due to figuring out the statistical possibility of having X things wrong with me was next to impossible without a common cause, and the ME/CFS with brain fog was destroying my life.
I also tried to quit caffeine but that only resulted in very negative effects that persisted for more than 4 months after going cold turkey, that's 4 months being largely housebound and not able to work for that one experiment. I've been at this so long that if you can think of something I've probably tried it - including the healthiest of healthy lifestyles.
Just comparing within my own family most are anti-drugs and anti-medications and their health is an absolute mess. I wish living a healthy lifestyle would be sufficient, I wouldn't have to walk a tightrope of balancing meds, but I don't get that option.
Some people have conditions that make the way their brains work different than what is considered normal. Western technological culture imposes differences in social interaction and pressures on thinking and required performance that are far different than existed in societies even mere hundreds of years before.
Drugs can be a way to compensate for these pressures and find a way to exist in the world with as much equanimity as possible. And I say all this as a person who avoids all caffeine and illegal drugs, and uses alcohol very infrequently. I'm lucky I can do this and thrive in today's Western culture. Not everyone is as fortunate.
My use is also light and fully legal, but personally I’m not sure that this is something that’s so binary. It seems more likely to sit on a spectrum, as most things do, and is largely dependent on the individual due to wide differences in brain and body function. It’s the same reason why the prescription drug that works wonders for one person and do nothing or worse, be detrimental for somebody else. We’re not all identical units of a particular model rolling off an assembly line somewhere, after all.
So I guess I would say that yes, we should be more conscientious of how substances (even those that are common) interact with our minds, but I have a hard time labeling them all as harmful. It’s just too broad of a brush.
I do a lot of DIY psychopharmacology, mostly modafinil and amitriptyline, in a successful effort to reduce ME/CFS/hEDS related brain fog. I’ve given modafinil to normal people and they tend not to notice any effects where for me it’s a super strong drug that’ll keep me wired unless I take other drugs to calm down.
I think quite a large subset of human behavior is seeking self medication for genetic anxiety disorders and I think in knowing the mechanisms people can avoid stumbling around in the dark and go directly towards things that work.
