I completely agree. Former and current opiate addicts I've met have told me that when contaminated pills are all you've got to stave off withdrawal, the risk from Tylenol poisoning doesn't really even cross your mind.

Adding risk (whether it's the risk of liver failure or prison time) to addiction behaviors doesn't do a damn thing, because addiction is a disease that fundamentally destroys our ability to make rational cost-benefit decisions when our drug or behavior of choice is concerned.

Agreed. An opiate OD can be reversed if caught in time. NSAID ODs box your liver.
