I have no sympathy for the ‘moral weakness’ that is drug addiction

I don’t care about self-inflicted problems, such as drug-taking. 

My approach to such people would be to remove them from the streets to spare decent citizens the sight of this detritus. Forget about what other countries do to pander to morally-impotent drug users.

Do not provide publicly funded services for these people, unless users pay for such services themselves.
