I think it's important to distinguish the hardcore anti-pharmaceutical attitude from the more reasonable position that, while someone may perform better while taking a medication in some measurable aspects, it may nonetheless be ideal to leave people unmedicated if they would not otherwise be destitute. We may thus model the medicated state as a local maximum but perhaps not the desired result (in particular, we have chosen to err on the more familiar side of the state-space). Conversely, I would have a hard time arguing against, if someone found that moderate regular alcohol consumption had a curative effect on a severe problem, their choosing to continue it.
