Oh no I may have phrased that poorly. I used "crazy pills" there in reference to the GP comment, definitely not as a reference to psych medications.
I don't have the stats handy though I do remember psych meds being a high proportion of those on prescription drugs.
The even more interesting/concerning (IMO) related stat is that the US military recently released a report that 77% (going off memory here, if that's not exact it was very close) of 18-24 year olds wouldn't be deemed fit for service and a majority of that was related to psych med prescriptions. Nothing wrong at all with taking those meds when they are needed, just an insight into how many younger people couldn't enlist due only to that rule.
