Well you packed quite a bit in there and there and I got lazy. But my points stand.
Medication can be valuable for mental health, but there are risks. While there are abuses of this, it still doesn't discount the value for those it does help.
Psychedelics/Ketamine/MDMA are showing great promise in therapeutic contexts and it's about time they are allowed to be used. They also can be enjoyed recreationally (and also abused), but again, that doesn't discount the legitimate medicinal use of them.
Your approach seemed to be that people just need to be born in the right community and upbringing and have a good life and everything will be all right.
The War on Drugs has been a catastrophic failure and attitudes such as yours support the continuation of that mistake.
