As do people who are infected with Rabies. Or rare forms of violent schizophrenia. Indeed, violent offenders are often not users of drugs, but from my understanding: the cutthroat underground distributors.

Which is why cops should continue to focus on the violent distributors of drugs. But social workers and hospital workers should step up their responsibility and start treating drug abusers better.

Or perhaps, more programs need to be made so that hospital workers / social workers are paid to fix this drug problem.

Hint: throwing drug USERS in jail, where they only get more underground connections and better learn to become a criminal, will start a cycle where they have to end up in jail again. Jail is just about the worst place you can put a person.
