Summary
Smoking negatively impacts the nervous system, affecting brain development, function, and increasing risks for diseases. Nicotine in tobacco smoke has multidimensional neurological health consequences.
Area of Science:
- Neuroscience
- Toxicology
- Public Health
Background:
- Tobacco use is a global health issue with over 5000 chemicals in smoke.
- Smoking's detrimental effects on the human body are well-documented.
- The impact of tobacco on the nervous system is a critical area of research.
Purpose of the Study:
- To review recent research (2015-2020) on tobacco's effects on the nervous system.
- To summarize findings on perinatal and adult nervous system development and function.
- To consolidate knowledge on animal and human studies concerning tobacco and the brain.
Main Methods:
- Systematic review of 1245 studies using keywords: tobacco, cigarette, nervous system, brain, morphology, function.
- Analysis of 200 significant abstracts from the reviewed literature.
- Synthesis of findings on neurological impacts across various studies.
Main Results:
- Tobacco significantly impairs nervous system development and neurotransmission.
- Smoking negatively affects cognitive functions and promotes neurodegenerative diseases.
- Cerebrovascular diseases and insomnia are linked to tobacco use, with a noted exception for dopaminergic protection in Parkinson's disease.
Conclusions:
- Recent research highlights numerous detrimental effects of tobacco on neurological health.
- Nicotine in tobacco smoke profoundly impacts the nervous system in multifaceted ways.
- Continued research is vital to understand and mitigate tobacco's neurological risks.

01:23Drugs Acting on Autonomic Ganglia: Stimulants
1.8K
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...

01:27CNS Depressants: Alcohol and Nicotine
601
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...

573
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...

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

01:29Drugs Affecting Neurotransmitter Synthesis
1.8K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
443
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...
