I'm all fine with stigmatising the current use of prescription drugs to treat mental issues. And that's not stigamtising mental health, it's promoting it with the push for more better treatments of the root causes. At this point only scientists struggle to come up with undeniable prove mental issues are mostly environmental, maybe if the sociology branch could step into cross disciplinary research but they would introduce a whole lot of noise. Of course there are genetic factors or plain genetics as the causes but even then, the popular treatments are questionable at least.
