Compulsory treatment for drug-dependent persons: justifications for a public health approach to drug dependency.

Compulsory treatment for drug users is often rejected as neither an effective nor an acceptable exercise of state authority.

Finally, a program of compulsory treatment can be shaped with concerns for due process in mind, so that civil liberties will not be violated.
