Over 92,000 drug-related overdose deaths, the majority of which were due to opioids, were reported in the U.S. in 2020 (https://www.cdc.gov/nchs/nvss/vsrr/drug-overdose-data.htm). This increase in opioid-related overdose deaths occurred despite the availability of several effective treatment medications. Both positive and negative reinforcing effects of opioids may underlie the initiation of opioid use and development and maintenance of opioid use disorder (OUD). Some investigators suggest that the negative reinforcing effects of opioids become more prominent with repeated use. Evidence for this position will be presented using clinical data from a variety of sources. While both processes appear to be supported by the data, the relative contribution of positive and negative reinforcing effects in maintaining opioid use is unclear. Additional research should be conducted to directly address this issue because it has relevance for the development of more effective pharmacotherapeutic and behavioral treatment strategies for OUD.
|Instruction Level: Intermediate|
|Target Audience: Basic researchers and clinicians|
|Learning Objectives: At the conclusion of the presentation, participants will be able to: (1) examine clinical laboratory data using self-administration paradigms and subjective reports of drug effects and opioid withdrawal symptoms to assess the positive and negative reinforcing effects of opioids; (2) characterize opioid self-administration among individuals who are maintained on medications for treating OUD; (3) evaluate self-reported reasons for using heroin among a large cohort of individuals with OUD.|
