It might be a struggle at some stage of addiction, where personal choice is less accessible. But at some earlier stage, it is a personal choice to experiment with hard drugs in the first place, and there is individual agency and responsibility associated with that choice.
Coddling addicts (by possibly excusing/overlooking any associated criminal actions) because it is a struggle in a later stage of addiction seems like a removal of the disincentives that keep people from going down that path in the first place. Also, I really am not for social support or a different (relaxed) enforcement of the law for addicts _above_ the protection of law-abiding citizens and their property.
