> And no, please spare us all your justifications for how caffeine is fine or micro-dosing has been amazing, because they are simply varying levels of rationalization, I do it too, I’m just not in it as deeply. And no, just because you were able to become rich with and on the back of drugs does not mean you did it without harm, you likely just scandalized a lot of harm to, e.g., get rich selling some service to some coke head investor who will only fuel the abuse of data mining and social media addiction.
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.
