True Left

What is the True Leftist opinion about addiction to hard drugs and drug addicts in general? I noticed that drug harm reduction principles are much more popular in left-leaning circles than with rightists:

Harm reduction is exactly what it sounds like: reducing the harm associated with using drugs through a variety of public health interventions. But the concept relies on more than these tools and begins, at the most fundamental level, with recognizing that all people deserve safety and dignity. It does not treat drug use as a moral failing.

(Of course, I don't think everyone deserves safety and dignity.)

I know that True Leftists are against the War on Drugs, but I was wondering if True Leftists criticize drug addicts (especially those that are trying to recover but are unsuccessful) for lack of willpower or other inner qualities.
