Presumably, the intent of punishing people who supply drugs with harsh sentences is to deter others from supplying drugs that result in an overdose. However, it's widely understood that punitive sentences for drug offenses have no deterrent effect. In fact, those prosecuted under this law would likely be low-level street dealers rather than the "kingpins" intended to be targeted. In many cases, these dealers may even be adolescents. Even if the law is effective at imprisoning dealers, the supply chain for controlled substances is not eliminated because a single seller is incarcerated, whether for homicide or otherwise. Supply follows demand, not the other way around. Incarceration of drug dealers simply results in a replacement effect, meaning that the market responds to the demand for drugs by merely opening the market for another seller.
