"The wide international variation in the availability of opioid agonist treatment for opioid-dependent injection drug users, despite documented scientific evidence in support of its efficacy, highlights the impact of political and philosophical forces that determine the availability of this treatment. Few proven therapies for medical conditions are restricted in this fashion. Therefore, efforts to address the political and philosophical opposition to opioid agonist treatment are needed to meet the global needs to prevent HIV transmission."
