This really just feels like fearmongering because this is a threat to big pharma. I mean, several commonly prescribed antidepressants have black box warnings about increased risk of suicide. When they trialed Prozac on people with no history of mental illness, someone committed suicide out of the blue. Fairly certain someone could cobble together a much more compelling meta analysis about even worse adverse effects of psych meds on similar populations, but due to NAMI and big pharma I think there's pressure not to draw those lines too clearly.
I think there's a clear bias in cases of big pharma approved meds to jump to "Oh, it wasn't the medication, the condition just worsened" and with psychedelics/weed to jump to "The substance use is causing this". Even when there is proof of RX medication worsening mental health conditions, it's common to have these relationships straight up denied by the prescribing doctor.
This isn't to say that there isn't a similar relationship in psychedelics, but it feels really disingenuous to me to be mentioning this outside of the wider context of psychiatric meds which somehow get a free pass for causing a much wider and dangerous range of side effects. If psychedelics cause less harm than commonly prescribed drugs in the same population, isn't that a good thing? We should understand these harms, but the bias of Big Pharma needs to be taken out of the picture.
