I disagree.
"Medication" (i.e. drugs) should be used if you want, regardless of any "extreme" case or lack thereof.
The only business it is of yours is if a) you're paying for it or b) it causes the user to infringe on your rights, in which case that, and not the drug use, is the only issue.
Trying to create some objective guide for drug use only empowers the psychs and the state to run your life in the "proper" manner.
