@Charles:

I think is it crazier because it is interfering with health-care, the medicine stores. To argue about drug abuse is one thing, people can attempt suicide on sleeping pills, get addicted on painkillers, suck on paste, etc., but, this is actually different when we are talking about already regulated drugs. It is almost as if regulation on guns is not enough and shutting down the gun stores (similar and hopefully won't happen because of the protection of Constitution).
