1. Tobacco use is the leading preventable cause of death worldwide, killing over 6 million people annually. This number is projected to rise to over 8 million deaths by 2030.
2. Cigarettes contain over 4,800 chemicals, including 69 that cause cancer. Smoking causes diseases like lung cancer, emphysema, and heart disease and reduces life expectancy by 10-14 years on average.
3. Secondhand smoke kills over 600,000 non-smokers annually through diseases like lung cancer and heart disease. Children exposed to secondhand smoke are also at risk for health issues.
1. Vaping associated lung injury (EVALI) was initially recognized in the summer of 2019, with over 1400 cases reported to the CDC.
2. Clinical features include shortness of breath, cough, hypoxemia, chest pain, nausea, vomiting and abnormalities on chest imaging.
3. Lung biopsies show patterns of acute lung injury including acute fibrinous pneumonitis, diffuse alveolar damage, and organizing pneumonia.
4. Treatment involves supportive care with oxygen and systemic glucocorticoids for more severe cases.
Smoking has been widespread in Britain since the 16th century, though its health risks were not firmly established until the 1950s. Currently, about 12 million British adults smoke, with rates highest among younger people and those from manual socioeconomic groups. Smoking causes over 100,000 deaths per year in the UK due to increased risks of cancer, heart disease, and respiratory illness. While some believe there are benefits to smoking like stress relief, evidence shows smokers have higher stress levels and that smoking provides only temporary relief through addiction, not actual stress reduction.
This document discusses public health concerns about vaping and e-cigarette usage. It provides information on what e-cigarettes are, the health effects which include lung illnesses and diseases, the rise of vaping-related illnesses in Texas, the popularity of e-cigarettes among youths, the federal response which will remove unauthorized flavored e-cigarettes from the market, and proposed changes to local smoking ordinances to expressly include vaping.
Overview of electronic cigarettes including history, components, safety and adverse events, efficacy in smoking cessation, pharmacokinetics and epidemiology. This presentation was originally delivered to 2nd year pharmacy students as part of a two semester class on pharmacology and toxicology.

Tobacco use is the leading preventable cause of death in the United States, killing over 400,000 Americans each year from diseases like lung cancer, heart disease, and stroke. Tobacco contains over 7,000 chemicals, including nicotine, tar, carbon monoxide, ammonia, and arsenic. While tobacco companies promote myths that some tobacco products like cigars, hookahs, and cloves are safer, all tobacco products are addictive and cause serious health issues. Quitting smoking can significantly reduce health risks, and medications and support groups can help in quitting.
The electronic cigarette was invented in China in 2004 by pharmacist Hon Lik. It consists of a battery, cartridge containing liquid (often with nicotine), and atomizer. When used, it produces an aerosol that some studies have found contains toxic chemicals and particles, though at lower levels than cigarette smoke. Nicotine in e-cigarettes is highly addictive and can be toxic at low levels, especially for youth. Major tobacco companies have entered the e-cigarette market due to declining cigarette sales. While e-cigarettes may contain fewer toxins than cigarettes, they are not harmless.
This document summarizes the negative health effects of smoking cigarettes. It discusses how cigarettes contain over 4,000 chemicals, including 60 carcinogens like nicotine, tar, carbon monoxide, and formaldehyde. Smoking temporarily increases heart rate and blood pressure and damages heart and blood vessels over time. Long-term effects include increased risk of lung cancer, COPD, premature aging, wrinkles, low sperm count, emphysema, heart disease, and strokes. The document also notes that smoking during pregnancy can negatively impact the baby's health and development.
The document discusses the health effects of tobacco use and provides advice for quitting smoking. It notes that tobacco use is a leading cause of death globally and is linked to various cancers and respiratory and heart diseases. It then gives tips for creating a quit plan, dealing with withdrawal symptoms, using cessation products, and seeking professional help if needed. The overall document provides information on the dangers of tobacco and guidance for developing a strategy to quit smoking successfully.
The document summarizes smoking statistics and tobacco control efforts in the Philippines. It reports that 22.7% of adults currently smoke, with 40.3% of men and 5.1% of women smoking. Every 10 seconds someone dies from smoking worldwide, and 10 Filipinos die every hour from smoking. The average monthly expenditure on cigarettes in the Philippines is 678.4 pesos. Republic Act 9211 established nationwide smoking bans and restricted tobacco advertising and promotion to reduce smoking prevalence and its health impacts. National smoking cessation programs aim to help smokers quit and support non-smokers in facilitating the cessation process.
Smoking refers to inhaling and exhaling the fumes of burning tobacco in products like cigarettes, cigars, and pipes. It contains over 4000 chemicals, 50 of which cause cancer. Smoking rates in Bangladesh are high, with 48% of the young population smoking. Smoking leads to numerous health risks like cancer, cardiovascular disease, respiratory illness, and premature death. Treatments include nicotine replacements, medications, and behavioral therapies to help people quit this addictive and dangerous habit. Education and prevention efforts can help reduce smoking rates and create a healthier world.

This document discusses the harms of smoking. It begins by defining a cigarette and outlining their history. Cigarettes contain over 4000 chemicals, including 60 carcinogens. People smoke for various reasons like social pressures. Smoking causes serious health issues like cancer, heart disease, and strokes. It also pollutes the air, soil, water and contributes to global warming. The document emphasizes that within just 20 minutes of quitting, the body begins improving and that stopping smoking fully removes the risks of smoking-related illnesses after 10-15 years.
This document discusses smoking, including what it is, reasons people start smoking, health effects and consequences of smoking, how nicotine leads to addiction, solutions to reduce smoking rates, and benefits of quitting smoking. It notes that smoking is the practice of inhaling smoke from burned tobacco or other substances, and the most common method is through cigarettes. Smoking can cause various health diseases and is costly. Nicotine is highly addictive and triggers dopamine release, leading to withdrawal symptoms when not smoking. Suggested solutions include increasing cigarette prices, limiting youth access, and raising awareness of health risks through warnings and campaigns. Benefits of quitting include improved health, more energy, savings of money, and better taste/smell.
The document discusses smoking and its consequences. It defines smoking as inhaling the smoke of burned substances like tobacco. It then lists some common reasons why people smoke, such as following the behaviors of parents/friends or managing stress. The document outlines several potential symptoms of smoking, including bad breath, discolored teeth/fingers, and various respiratory issues. It also discusses some serious health consequences of smoking like various cancers, emphysema, and strokes. The document concludes by providing some tips for quitting smoking and sharing smoking statistics.
A presentation created for Pulmonary Rehab to help patients with smoking cessation. Overview of cigarettes, e-cigarettes, triggers, withdrawals, and nicotine replacement therapies.
The document summarizes the effects of smoking on the human body. Smoking can cause dangerous respiratory diseases like asthma, tuberculosis, lung cancer, and emphysema by damaging the lungs and respiratory system. It also affects the digestive system, causing ulcers, stomach cancer, and heartburn. Long-term smoking significantly increases the risk of lung cancer, heart attacks, strokes, and many other health issues. It is estimated to have caused over 100 million deaths in the 20th century. The presentation emphasizes that smoking not only harms smokers but also bothers others with secondhand smoke.
This document provides guidance on using the 5As method to help patients quit smoking. The 5As include: Ask about smoking status, Advise smokers to quit, Assess willingness to quit, Assist with a plan to quit, and Arrange follow-up support. Key steps involve clearly advising patients of the health risks of smoking, helping set a quit date, recommending pharmacotherapy or other assistance, and following up over the first month to prevent relapse. The overall goal is to help smokers understand smoking dangers and develop a personalized plan to quit through counseling and support.
The document discusses nicotine and tobacco use. It defines nicotine as a toxic and addictive alkaloid found in tobacco. It then describes different routes of nicotine administration including smoking, oral consumption, and nasal inhalation. The effects of nicotine on the body and brain are explained, including increased heart rate and the release of dopamine and endorphins which produce pleasurable feelings. Statistics on tobacco addiction and the health risks of smoking are also presented.
The document discusses smoking cessation and approaches for quitting smoking. It covers the following key points:
- Part I provides an introduction and discusses the health effects of smoking.
- Part II outlines evidence that smoking increases risks of cancer and cardiovascular disease.
- Part III discusses the benefits of quitting smoking.
- Part IV describes two approaches - the 5A's model and 5R's model - that healthcare providers can use to help patients quit smoking through counseling and support. It details the steps in each model including asking about tobacco use, advising patients to quit, assessing willingness and barriers, assisting with treatment options, and arranging follow-up support.
This document discusses the harms of smoking tobacco. It notes that cigarettes contain over 4000 chemicals including 60 carcinogens and toxins like nicotine, tar, carbon monoxide, and arsenic. The document outlines the negative health effects of both active and passive smoking, including impacts on the blood circulation, respiratory, reproductive, and nervous systems as well as reduced immunity and risks to children and older adults. It closes by stating that over 3200 kids under 18 start smoking daily and that the FDA has launched education campaigns to curb smoking rates.
Smoking involves burning a substance, usually tobacco, and inhaling the smoke. Tobacco smoking is the most common form of smoking, practiced by over one billion people worldwide. Smoking has a long history dating back 5000 BC and was used in religious rituals before becoming popular for recreational use due to substances like nicotine. While tobacco and cannabis are most commonly smoked, other drugs like opium were also smoked, though smoking rates have declined in recent decades due to health concerns. Smoking carries significant health risks like cancer, heart disease, and lung damage.
Smoking is highly addictive and causes many serious health risks and diseases. Nicotine is the addictive substance in cigarettes that is as addictive as heroin or cocaine. Teenagers often start smoking due to peer pressure or mistaken beliefs that it makes them look cool or slim. However, smoking can cause cancer, heart disease, COPD and many other illnesses. It is the largest cause of preventable death worldwide. There are many resources available to help people quit smoking such as nicotine replacement therapies and lifestyle changes. Quitting smoking has significant health benefits and is important for both individual and public health.

This document provides information on vaping and tobacco harm reduction. It discusses how smoking kills over 96,000 people annually in the UK and notes that median smokers lose 10 years of life expectancy. It then examines smoking prevalence data in different areas and populations in the UK. The document discusses evidence that vaping is substantially less harmful than smoking and may help smokers quit. It notes concerns that restrictive policies could perpetuate smoking. The summary concludes by outlining a framework for risk-proportionate regulation of tobacco and nicotine products.
This study compared the effects of cigarette smoke, e-cigarette vapor, and pure nicotine on cell viability using HeLa cells. Various concentrations of smoke and vapor condensates collected from a mechanical smoking system were applied to cells for 24 hours. An MTT assay then measured cell viability. Cigarette smoke exposure resulted in lower viability than e-cigarette vapor, but higher than pure nicotine. The results provide insight into the acute toxicity of these substances and whether e-cigarettes may be less harmful than cigarettes.
Tobacco harm reduction - meetings with Hill staff Clive Bates
This document discusses efforts to reduce smoking and associated harms. It notes that while 36.5 million Americans smoke, consuming 264 billion cigarettes in 2015, smoking causes over 480,000 deaths per year at a cost of over $300 billion. New reduced-risk nicotine products like e-cigarettes and heated tobacco have potential to significantly reduce smoking's toll if made accessible through sensible regulation rather than restrictive policies that protect the cigarette trade. The Royal College of Physicians reviewed evidence that e-cigarettes are much less harmful than smoking and effective for smoking cessation. Most youth e-cigarette use involves just flavors without nicotine. Banning flavors could undermine harm reduction efforts. The proposed Cole-Bishop bill offers a responsible
Tobacco Harm Reduction - an introductionClive Bates
This document provides an introduction to tobacco harm reduction and alternative nicotine products such as e-cigarettes. It summarizes statements from public health organizations that find e-cigarettes to be much less harmful than combustible cigarettes. Research shows e-cigarettes help smokers quit at the population level and are effective cessation tools. The document argues for risk-proportionate regulation and taxation of nicotine products to incentivize smokers to switch to less harmful options and further reduce smoking rates.
Innovation for Consumers: E-cigarettes and novel tobacco products - Part of t...Clive Bates
This document discusses e-cigarettes and novel tobacco products. It argues that they are substantially less harmful than combustible cigarettes and have the potential to significantly reduce smoking rates and associated deaths. However, regulations should balance this potential benefit with preventing unintended consequences like perpetuating smoking or increasing youth uptake. The document proposes risk-proportionate regulations and taxes to incentivize switching from cigarettes, along with standards, marketing restrictions, and age limits, while ensuring products remain appealing to smokers trying to quit. The goal is harm reduction for populations according to the WHO framework convention on tobacco control.
This document summarizes information presented at a tobacco harm reduction conference on the public health benefits of tobacco harm reduction. It discusses estimates of the relative harm of nicotine products, value propositions for smokers to switch to lower-risk alternatives like e-cigarettes, real-world examples of smokers switching successfully to e-cigarettes, and projections of global cigarette consumption trends with and without the introduction of reduced-risk nicotine products. It also examines how moral panics have emerged around issues like e-cigarette poisoning, use by youth, hidden toxicants, and youth-oriented flavors.
E-Cigarettes: Promise, Peril, and Probabilistic Population PredictionCertara
E-cigarettes, which deliver nicotine without carcinogenic tar, hold the promise to save the lives of many smokers who switch to them, but risks include failure to quit cigarettes (dual use), increased initiation to nicotine products among youth, relapse of former smokers to e-cigarettes, and e-cigarettes becoming a “gateway to smoking.” To capture these uncertainties and weigh benefits vs. risks, prediction of e-cigarette health impacts must use a broad range of probability-weighted scenarios.
E-cigarettes provide an alternative to nicotine delivery through vapor rather than smoke. While they may be less harmful than conventional cigarettes, there are still health risks and unknown long-term effects. The document discusses both sides of the debate around e-cigarettes. Some view them as a harm reduction tool that can help smokers quit, while others are concerned they could renormalize smoking behaviors and expose users to carcinogens. Long-term studies are still needed to fully understand the safety profile of e-cigarettes and their impacts on public health.
Electronic Cigarettes: Evidenced Based Decision Making PresentationKaylaRobinson29
An assignment for Dental Hygiene Theory 1 was to create an annotated bibliography for a research topic of our choice. This project was designed to challenge our critical thinking and decision making skills. I chose to research electronic cigarettes and their effects on oral health. It was interesting to compare different literature on this subject and the validity that they held. Most of the articles were very similar in the information portrayed and were very educational.
This document discusses electronic cigarettes (ECs) and whether they are safer than combustible cigarettes. It summarizes that while ECs may expose users to fewer harmful chemicals than smoking, the long-term safety of ECs is still unknown. Studies have found potentially harmful chemicals in EC vapor, but in much lower amounts than in cigarette smoke. The regulation of ECs is also debated, as stricter rules may discourage innovation but make the products less appealing to youth and non-smokers. The evidence that ECs help smokers quit is also limited and inconclusive. More research is still needed to understand the public health impact of ECs.
Tobacco Harm Reduction by Somchai Bovornkitti* in Crimson Publishers: Telemedicine and e-Health open access journals
Cigarette smoke contain approximately 250 different chemicals known to be harmful to human health. Thousands of harmful chemical substances produce by the combustion of tobacco. The health impacts such as cancer and chronic lung disease are not only associated with smokers but also people who are exposed to secondhand smoke. Tobacco Harm Reduction is a concept to minimize the impacts of tobacco on the individual and on society at large. A key component of this strategy is using alternative source of nicotine as a substitute to tobacco cigarettes. Electronic cigarette and heated tobacco are alternatives that might have potential in reduce harm from smokes. This paper elaborates on available research associated with electronic cigarette and heated tobacco with harm reduction and risk perspective.

- The document discusses nicotine testing methods and their use in various contexts like insurance, employment, schools, and research. It also covers nicotine metabolism and the differences between nicotine and its metabolite cotinine.
- The Nano-Check Rapid Nicotine Test is described as an immunoassay that detects cotinine in urine at cutoff levels of 200ng/ml or 500ng/ml to determine tobacco use. It provides results in 5-10 minutes and is intended for professional use.
- The test works by detecting cotinine in a urine sample via monoclonal antibodies on a test strip, with positive or negative results depending on whether or not a test line appears within the timeframe.
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

8. UK E-Cig Policy
1. Consumer route
• Notification process
• Minimum standards for safety, quality,
nicotine and size limits
• Standard packaging & labelling
requirements
• Advertising regulations
• Yellow card system for side effects &
safety reporting
2. Medicinal licensing route
• Different standards for safety and
quality, higher nicotine levels
allowed
• Advertising allowed
• But none yet marketed

9. Some issues with E-cig regulations
• No advertising = less presence, less reach = more
smoking
• Addiction warning labels: intimidating message; may put
smokers off (Cox et al. 2018, Addict Beh Reports)
• Caps on nicotine content: may not relieve cravings for
the heaviest smokers; encourages more use &
compensatory puffing (Dawkins et al. 2016, Psychopharm)
• Limits on tanks and bottle sizes = more refills, more
hassle, more to remember = easier to smoke.
• US – limits on change to products = improvements
(including safety) restricted = unnecessary harm

15. What’s wrong with nicotine?
Prof Michael Russell:
“People smoke for nicotine
but they die from the tar”
(1976)
Components of Tobacco Smoke:
Nicotine: main active ingredient = addiction
Tar: Sticks to lungs/airways allowing cancer-
causing compounds to build up resulting in
cancers & respiratory disease
Carbon Monoxide: toxic gas prevents
O2transport & produces cardiovascular disease
TOBACCO HARM REDUCTION: Give smokers the nicotine they desire
without the harmful effects of burning tobacco

Public perceptions of nicotine harms
How much of the
harm from
smoking
cigarettes comes
from nicotine?
2,103 11-18 yr olds in
Great Britain in 2016
17. Is continued nicotine addiction a
problem?
• Long term use of Nicotine Replacement Therapy (NRT) not shown to be
harmful (Murray et al. 2009, Nicotine Tob Res)
• A problem for whom?
• Public health? – no as completely switching to vaping dramatically
reduces the risk of smoking-related disease
• The individual? - maybe if cost, others’ perceptions, enslavement etc. is
an issue
• Limited research but some evidence that nicotine via vaping is less
‘addictive’ than via smoking (e.g. Dawkins et al. 2013, Addiction; Foulds et al. 2017, Prev Med)
19. Nicotine delivery from smoking vs. vaping
• Smokers smoke
intermittently;
vapers ‘graze’
• Less efficient
nicotine delivery
from vaping
• Vapers puff more
with lower nicotine
strength liquids but
maintain a steady
nicotine intake (Soar
et al. 2018)

25.
26. • Burning: combustion is key
• Cigarette smoke: 7000+ compounds, including 70 carcinogens burnt at ~800 °C
• E-cigarette vapour: mainly nicotine, PG/VG, flavourings, heated at ~200 °C
E-cigarette health effects: some things to consider
Need to ensure that research studies use realistic exposure
& measured effects are actually a marker of risk/disease
• Assessing harms is difficult
• Any possible harms of vaping will take years to emerge
• Hard to draw conclusions from animal studies
• Are vapour exposure conditions realistic?
• Human studies: most users are current/past smokers
• Is the biomarker meaningful?
Slide adapted from Shahab, SRNT-E Munich (2018). Source: McNeill et al. (2018). Chapter 9.
27. Using biomarkers to estimate harms
• Biomarker – something that can be measured and which can be used
as an indicator of a particular disease state.
• Can be tested now
• Short-term/reversible
• Have to be reasonably specific and linked to disease (e.g. NNAL)
NNAL
Nitrosamine
(NNK)

41. Pathways of use
• Two surveys from the UK and several US studies found that young
people who have never smoked but have tried an e-cigarette at the
beginning of the study are more likely to have gone on to try smoking
several months or years later.
• This suggests there may be an association but we cannot establish a
cause based on these findings
• ‘Common liability’ likely explains these findings (i.e risk taking
behaviour)
• Some data to suggest the opposite trend – i.e. that e-cigarettes may
be a route out of smoking for some young people

44. Summary of myths/concerns
• There hasn’t been enough research
• They’re not regulated
• Everyone’s using them
• It’s just transferring an addiction to nicotine
• People use them constantly – that must be bad
• They’re always exploding / they catch fire
• They’re just as harmful as smoking
• They don’t help smokers to quit smoking
• They may lead young people to start smoking
