Substance use disorders (SUDs) are highly stigmatized conditions, with stigma hindering and discouraging individuals from seeking treatment services. Not only does stigma exist for individuals with SUDs, but also for individuals who use medications to treat opioid use disorders despite the unparalleled effectiveness of medication-assisted treatment (MAT). Stigma is perpetuated through both expected (families and employers) and unexpected (health care providers) routes. During this webinar, participants will learn about the ways in which stigma undermines treatment opportunities and increases individuals’ shame that can lead to adverse outcomes, including overdose.
