Stimulants01:29

Stimulants

770
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants

2.0K

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

CNS Depressants: Alcohol and Nicotine

914
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...

Physical Properties Affecting Solubility02:19

Physical Properties Affecting Solubility

25.9K
Solutions of Gases in Liquids
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...

2° Amines to N-Nitrosamines: Reaction with NaNO2

5.2K
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

Solution Equilibrium and Saturation01:59

Solution Equilibrium and Saturation

21.3K
Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...

Summary

Discarded cigarettes in beverages can leach toxic nicotine levels, posing a significant risk to children. Nicotine concentration increases with more cigarettes and longer immersion times in drinks.

Area of Science:

  • Environmental Health
  • Toxicology
  • Analytical Chemistry

Background:

  • Tobacco products, like cigarettes, are often extinguished in beverage containers.
  • Accidental ingestion of these liquids has led to reported cases of nicotine poisoning, particularly in children.
  • Understanding nicotine leaching from immersed cigarettes is crucial for public health risk assessment.

Purpose of the Study:

  • To quantify nicotine concentrations in a beverage after immersing cigarettes.
  • To investigate the relationship between nicotine levels, the number of immersed cigarettes, and immersion duration.
  • To assess the potential toxicity risks associated with discarded cigarette beverages.

Main Methods:

  • Unsmoked cigarettes were immersed in a cola beverage within a soda can.
  • Samples were collected at various time points up to one week.
  • Nicotine concentrations were analyzed using liquid chromatography-mass spectrometry (LC-MS).

Main Results:

  • A mean nicotine concentration of 0.48 mg/ml was measured after 6 hours from one cigarette in 55 ml of cola.
  • Nicotine levels increased significantly in the first 6 hours, then plateaued.
  • A strong positive correlation was observed between nicotine concentration and both the number of cigarettes and immersion time.

Conclusions:

  • Nicotine concentrations from immersed cigarettes in beverages can reach potentially toxic levels, especially for children.
  • Both the quantity of cigarettes and the duration of immersion directly influence nicotine leaching.
  • These findings highlight the dangers of improperly discarded smoking materials in accessible containers.
