Abstract

Background:

Few studies exist examining alcohol and opioid co-use mortality rates among racially and ethnically diverse communities, presenting a critical gap in understanding the contribution of alcohol on opioid-related deaths and strategies for prevention. The purpose of the study was to assess whether alcohol and opioid-related deaths differ by race/ethnicity subgroups and if there has been an increase in alcohol and opioid-related deaths between 2011 and 2017.

Design:

Secondary data analysis of publicly available alcohol and opioid mortality data among non-Hispanic Whites, Black, Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native individuals in Washington State.

Measurements:

The primary outcomes were alcohol-only, opioid-only, and alcohol-opioid co-use mortality, 2011-2017. Alcohol and/or opioid-related deaths were assigned an International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for the underlying or multiple cause of death.

Findings:

Between 2011 and 2017, alcohol-only mortality rates increased among non-Hispanic White (P = 0.003) and Hispanic individuals (P = 0.008). Opioid-only mortality rates increased among American Indian/Alaska Native (P = 0.004) and Hispanic individuals (P = <0.001). American Indian/Alaska Native individuals had the highest alcohol-only, opioid-only, and co-use-related mortality rates when looking at between-group incidence rates.

Conclusions:

Although the opioid epidemic has been characterized as a public health crisis that predominantly impacts non-Hispanic White individuals, racial and ethnic minorities are increasingly impacted by fatal and non-fatal overdose related to co-occurring substance use. Our findings using data from Washington State, align with existing data and signal a dire need to address alcohol and opioid misuse through targeted interventions to prevent overdose and poisoning, with special considerations for American Indian/Alaska Native communities.

Opioid Analgesics: Morphine and Other Natural Cogeners

Opioid Analgesics: Morphine and Other Natural Cogeners

Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Hypothesis Test for Test of Independence

Hypothesis Test for Test of Independence

The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Depressants

Depressants

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

CNS Depressants: Alcohol and Nicotine

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
