While the article is a little dated, it's also a little misleading since he's describing all brain altering drugs, such a opioids.
Still not great, but the devil's advocate could still argue that mandatory rehab at a commune for drug abuse is quite reasonable (especially over prison). What's problematic is him making it a labor camp, and including things like Adderall even if it doesn't quite sound mandatory in their case. Adderall abuse certainly exists, as with most things, but it's certainly no heroin.
Right now the status quo sucks, though, as far as drug rehab and government services are concerned. Since at least Reagan, we've gutted those services to those who need it. Just wish it wasn't these assholes filling that void. Really need a progressive in office...
