Background: The above-average proportion of people with opioid use disorder living in prisons is a worldwide reality, and the need to treat these people was recognized internationally more than 20 years ago. Studies have shown that substitution therapies are best suited to treat opioid use disorder and reduce the risk of HIV and hepatitis C transmission and overdose. However, huge health inequalities exist in and outside of prison due to the different implementation of opioid substitution therapy (OST). People living in prisons are entitled to the best possible health care. This is established by the Universal Declaration of Human Rights and by the International Convention on Economic, Social and Cultural Rights. Solely the imprisonment, and not the loss of fundamental human rights, constitutes the punishment.
Methods: A qualitative literature search using PubMed and Google Scholar was performed in order to identify relevant publications.
Results: This review shows the inequality in availability of opioid substitution therapy for people living in prison compared with people outside of prison in Germany. It also gives possible reasons and evidence for this inequality, showing that continuing or initiating OST in prison is more beneficial for the health of people living in prison than abstinence-oriented treatment only.
Conclusion: It is important that drug use disorder is treated as a serious illness also in prison. Joint efforts are needed to provide people living in prison with the best possible treatment and to minimize the adverse effects of drug use. Therefore, with laws, policies, and programs that conform to international human rights standards, each state must ensure that people living in prison receive the same health care as people outside of prison.
