    Adverse Childhood Experiences (ACEs) and Their Impact on Substance Misuse & Overall Health
    (The Center for Health Policy, 2018-03-01) Balio, Casey; Greene, Marion S.
    Adverse childhood experiences (ACEs) encompass a wide variety of distressing events, including emotional, physical, or sexual abuse; witnessing maternal domestic violence; or living with a household member who has a substance use disorder, is mentally ill or suicidal, or is currently or was ever incarcerated during the first 18 years of a child’s life. According to most recent estimates, nearly half of Indiana’s youth have experienced at least one ACE in their life. ACEs are linked to many risk behaviors, including substance use, which can adversely affect health outcomes.

    Community Conditions Favorable for Substance Use
    (The Center for Health Policy, 2018-04-01) Jacinto, Corey; Greene, Marion S.
    The probability of whether an individual engages in substance use is associated with several risk and protective factors. Effective prevention requires understanding these factors. The social-ecological model considers the complex interactions between individual, relationship, community, and societal factors. This can help us understand substance use in a public health context and design strategies to address the problem across multiple levels.

    The Impact of Substance Use on the Developing Brain
    (The Center for Health Policy, 2017-07-01) Kooreman, Harold E.
    Most peoples’ first exposure to alcohol, tobacco, and other drugs typically occurs during adolescence, a time when the brain changes rather dramatically. The maturation process of the adolescent brain is reflected in a greater propensity to take part in risky activities such as unprotected sex, reckless driving, and substance use. Alcohol, nicotine, and marijuana, the most commonly used substances by teens, have all been tied to disruptions in normal brain development. These structural changes are associated with higher rates of cognitive impairments and academic difficulties, higher rates of future substance use and substance use disorders, and higher rates of mood and psychotic disorders.

    Leveraging genome-wide data to investigate differences between opioid use vs. opioid dependence in 41,176 individuals from the Psychiatric Genomics Consortium
    (Springer Nature, 2020-08) Polimanti, Renato; Walters, Raymond K.; Johnson, Emma C.; McClintick, Jeanette N.; Adkins, Amy E.; Adkins, Daniel E.; Bacanu, Silviu-Alin; Bierut, Laura J.; Bigdeli, Tim B.; Brown, Sandra; Bucholz, Kathleen K.; Copeland, William E.; Costello, E. Jane; Degenhardt, Louisa; Farrer, Lindsay A.; Foroud, Tatiana M.; Fox, Louis; Goate, Alison M.; Grucza, Richard; Hack, Laura M.; Hancock, Dana B.; Hartz, Sarah M.; Heath, Andrew C.; Hewitt, John K.; Hopfer, Christian J.; Johnson, Eric O.; Kendler, Kenneth S.; Kranzler, Henry R.; Krauter, Kenneth; Lai, Dongbing; Madden, Pamela A.F.; Martin, Nicholas G.; Maes, Hermine H.; Nelson, Elliot C.; Peterson, Roseann E.; Porjesz, Bernice; Riley, Brien P.; Saccone, Nancy; Stallings, Michael; Wall, Tamara L.; Webb, Bradley T.; Wetherill, Leah; Biochemistry and Molecular Biology, School of Medicine
    To provide insights into the biology of opioid dependence (OD) and opioid use (i.e., exposure, OE), we completed a genome-wide analysis comparing 4503 OD cases, 4173 opioid-exposed controls, and 32,500 opioid-unexposed controls, including participants of European and African descent (EUR and AFR, respectively). Among the variants identified, rs9291211 was associated with OE (exposed vs. unexposed controls; EUR z = -5.39, p = 7.2 × 10-8). This variant regulates the transcriptomic profiles of SLC30A9 and BEND4 in multiple brain tissues and was previously associated with depression, alcohol consumption, and neuroticism. A phenome-wide scan of rs9291211 in the UK Biobank (N > 360,000) found association of this variant with propensity to use dietary supplements (p = 1.68 × 10-8). With respect to the same OE phenotype in the gene-based analysis, we identified SDCCAG8 (EUR + AFR z = 4.69, p = 10-6), which was previously associated with educational attainment, risk-taking behaviors, and schizophrenia. In addition, rs201123820 showed a genome-wide significant difference between OD cases and unexposed controls (AFR z = 5.55, p = 2.9 × 10-8) and a significant association with musculoskeletal disorders in the UK Biobank (p = 4.88 × 10-7). A polygenic risk score (PRS) based on a GWAS of risk-tolerance (n = 466,571) was positively associated with OD (OD vs. unexposed controls, p = 8.1 × 10-5; OD cases vs. exposed controls, p = 0.054) and OE (exposed vs. unexposed controls, p = 3.6 × 10-5). A PRS based on a GWAS of neuroticism (n = 390,278) was positively associated with OD (OD vs. unexposed controls, p = 3.2 × 10-5; OD vs. exposed controls, p = 0.002) but not with OE (p = 0.67). Our analyses highlight the difference between dependence and exposure and the importance of considering the definition of controls in studies of addiction.

    Substance Abuse in Indiana: An Urban-Rural Perspective
    (The Center for Health Policy, 2017-06-01) Kooreman, Harold E.; Greene, Marion S.
    The use of alcohol and drugs is a significant public health problem in the United States. Indiana, like many other states in the nation, is lacking in substance abuse treatment services and rural areas are particularly underserved. Rural residents may encounter additional barriers to receiving substance abuse treatment, including stigma, fear that they may know their treatment providers, a lack of access to specialized services, inferior quality of care, and having to pay more for treatment.

    Substance Abuse Trends in Indiana: A 10-Year Perspective
    (The Center for Health Policy, 2017-04-01) Balio, Casey; Greene, Marion S.
    Substance use is a significant public health problem in the United States. Excessive use of alcohol and drugs has been linked to increased morbidity and mortality from cardiovascular conditions; injuries and motor vehicle crashes; sexually transmitted and blood-borne illnesses, including HIV/AIDS and hepatitis B and C, resulting from risky sexual behaviors and/or injection drug use; pregnancy complications and neonatal abstinence syndrome (NAS); and drug overdoses [5, 6].
