As the economy suffers and times get harder, more people turn to escapism in self administered street drugs. It’s estimated that only 10% of street drug imports are caught but it’s difficult to blame governments for not ignoring the cash cow of red handed dealer busts. There’s certainly enough of them.
Personally (it’s been on my freep page for years) I would be willing to permit physicians to administer anything for medical purposes as long as the physicians are willing to assume liability for any resulting harm. That would probably result in more existing addictions being humanely managed, and less worry about moot issues like getting the terminally ill hooked. This does not translate to a blind eye for street pushers.
Why should physicians need to assume liability for something that would have been passed into law by governing assemblies??
