There's a lot of new war veterans getting perscription weed now, too. Mostly for PTSD.
As for autism, there has been a lot of recent progress, but it's going to take years for it to reach most people. My old high school used to treat autistic kids and retarded kids the same way, though there are specific nuances to each disorder that need to be addressed on a person-to-person basis. All of the mentally handicapped kids are uaully grouped together, and kind of pushed through the curriculum, whether they retain the information legally required or not. Which is easy for everyone, but it means they're royally screwed later on.
The truth is, people don't really know what to 'do' with these people, and either they get pushed too hard or not at all, both of with impede development. The worst is when people look at a diagnosis, and just assume that a person is incapable of anything without someone to hold their hand. Most of the symptoms of aspergers are experienced by everyone, anyway. The inability to communicate exactly what one feels, or to understand everything that is occuring, a disconnection from other people, those are universal problems in the developed world. Asbergers is just a magnification of those problems, for the most part.
Ps- i don't know if these have been mentioned before, but 'The Curions Incident of the Dog in the Night Time' is an excellent read regarding this subject. So is 'The Stranger'. I know it wasn't written specifically about autisum/aspergers, but it is my own personal conspiracy theory that Merusault is autistic. Whether he is or not, he exhibits many of the symptoms, in a way that someone normal would. Which is chilling, if you know the story.
