"Proponents of public health approaches differ in their general views of substance use, ranging from broad disapproval () to the suggestion of potential benefits (); accordingly, some calls for a public health approach focus on prevention and treatment (), while others emphasize harm reduction (). Even among calls for a public health approach to opioids in North America, definitions range from those narrowly focused on population-level prevention via surveillance and research () to expansive ones that include a commitment to the principles of social justice, human rights, and equity (). So while public health approaches to substance use are frequently called for, what they are—or should be—remains unclear."
