Summary
Public health information campaigns are more effective when people are willing to receive the information. Experimental designs must account for this willingness to ensure accurate impact assessments for opioid epidemic policies.
Area of Science:
- Public Health
- Health Policy
- Behavioral Science
Background:
- Information campaigns are a common public health policy tool.
- Standard experimental methods may overestimate campaign effects by ignoring respondent receptiveness to information.
Purpose of the Study:
- To examine how willingness to seek information influences public opinion on opioid epidemic policies.
- To assess the impact of informational treatments considering individual choice in information reception.
Main Methods:
- A doubly randomized survey experiment was conducted on a national sample.
- Subjects were randomly assigned to receive information or to choose whether to receive it.
- The study focused on public preferences regarding opioid epidemic policies.
Main Results:
- Informational treatment significantly increased support for opioid policies by 0.5 standard deviations among receptive individuals.
- Individuals unwilling to receive information showed no change in policy preferences after treatment.
- Standard experimental designs would miss these differential effects.
Conclusions:
- Public receptiveness to information is crucial for the effectiveness of public health campaigns.
- Addressing information asymmetries is important but insufficient alone for the opioid epidemic.
- Future policy evaluations should consider individual willingness to engage with information.

1.4K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

848
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...

01:22Opioid Receptors: Overview
3.8K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

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...

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
