Insights

Child-resistant packaging laws significantly reduced liquid nicotine exposures in young children. Despite this decrease, liquid nicotine remains a serious risk, necessitating further regulation to protect children.

Area of Science:

  • Toxicology
  • Public Health
  • Pediatrics

Background:

  • Liquid nicotine, used in electronic cigarettes, presents a significant poisoning risk to young children.
  • Accidental ingestions of liquid nicotine can lead to severe health consequences.

Purpose of the Study:

  • To analyze trends in liquid nicotine exposures among children under 6 years old in the U.S.
  • To assess the impact of child-resistant packaging legislation on these exposures.

Main Methods:

  • Analysis of liquid nicotine exposure data from the National Poison Data System (2012-2017).
  • Comparison of exposure rates before and after the implementation of federal child-resistant packaging laws.

Main Results:

  • Over 8,000 liquid nicotine exposures in children under 6 were reported, primarily through ingestion.
  • Exposure rates peaked in 2015 and then declined, coinciding with legislative changes.
  • States without prior child-resistant laws saw a significant decrease in exposures post-federal law.

Conclusions:

  • Legislation mandating child-resistant packaging has contributed to a reduction in pediatric liquid nicotine exposures.
  • Despite progress, liquid nicotine remains a substantial hazard for young children.
  • Additional regulatory measures are recommended to enhance child safety regarding electronic cigarette products.

Cholinergic Receptors: Nicotinic01:15

Cholinergic Receptors: Nicotinic

Nicotinic receptors are ligand-gated ion channels that are activated by acetylcholine and nicotine. Upon activation, they cause a rapid increase in the permeability of cells to K+, Na+, and Ca2+, followed by depolarization and excitation. They are in the autonomic ganglia, skeletal neuromuscular junction, CNS, and adrenal medulla.
There are two types of nicotinic receptors: neuromuscular (NM/NM/N1) and neuronal (NN/NN/N2). The two families differ based on their location and selectivity to...

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...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Molecular Comparison of Gases, Liquids, and Solids02:26

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

Rise of Liquid in a Capillary Tube01:18

Rise of Liquid in a Capillary Tube

When very thin cylindrical tubes, called capillaries, are dipped in a liquid, the liquid rises or falls in the tube compared to the surrounding liquid. This phenomenon is called capillary action. Capillary action occurs due to the combination of two opposing forces: the cohesive forces of the liquid, which cause it to stick to itself and form a rounded shape, and the adhesive forces between the liquid and the walls of the container, which cause the liquid to be attracted to the container walls.

Deriving the Speed of Sound in a Liquid01:09

Deriving the Speed of Sound in a Liquid

As with waves on a string, the speed of sound or a mechanical wave in a fluid depends on the fluid's elastic modulus and inertia. The two relevant physical quantities are the bulk modulus and the density of the material. Indeed, it turns out that the relationship between speed and the bulk modulus and density in fluids is the same as that between the speed and the Young's modulus and density in solids.
The speed of sound in fluids can be derived by considering a mechanical wave...
