What You'll Learn
Tobacco kills more people than alcohol
Tobacco and alcohol are both harmful substances that contribute to a significant number of deaths worldwide each year. Tobacco is the more deadly of the two, constituting a substantial public health threat.
The World Health Organization (WHO) states that tobacco kills over 8 million people annually worldwide, with more than 7 million of those deaths resulting from direct tobacco use. In comparison, an estimated 100,000 deaths are attributed to alcoholism each year. While both substances significantly impact mortality, the disparity in numbers underscores that tobacco is the more lethal of the two.
The addictive nature of tobacco and the presence of harmful chemicals, such as nicotine, contribute to its high mortality rate. Nicotine addiction is strongly linked to cigarette smoking, and the close association between nicotine addiction and alcoholism is well-established. This comorbidity further exacerbates the health risks for individuals struggling with both addictions.
The dangers of tobacco extend beyond direct consumption. Second-hand smoke, which fills enclosed spaces like homes, offices, and restaurants, poses a serious health risk to non-smokers. Approximately 1.3 million people die prematurely each year due to exposure to second-hand smoke, emphasizing the far-reaching consequences of tobacco use.
While alcohol consumption also contributes to premature deaths and is a causal risk factor for numerous disease conditions, the risk associated with tobacco use increases more rapidly with consumption. Studies comparing alcohol and tobacco use in Canada found that males consuming five drinks per day faced an equivalent risk to smoking 4.9 cigarettes per day, while females consuming the same amount of alcohol experienced a similar risk to smoking 4.2 cigarettes per day. These findings highlight the relatively higher risk associated with tobacco consumption.
In summary, while both tobacco and alcohol are harmful substances, tobacco claims a significantly higher number of lives each year. The addictive nature of tobacco, the presence of harmful chemicals, and the dangers of second-hand smoke exposure all contribute to its status as a leading cause of preventable deaths globally.

80% of alcoholics smoke
Smoking and alcohol consumption are two of the most common causes of preventable deaths globally. Research has shown that smoking kills more people than alcohol, AIDS, car accidents, illegal drugs, murders, and suicides combined. In addition, smokers lose about a decade of their lives due to their smoking habit. Similarly, alcohol consumption is a causal risk factor for over 230 disease conditions.
It is well established that there is a close association between nicotine addiction and alcoholism. An estimated 80% of alcoholics smoke, and 30% of smokers are alcoholics. The mortality rate from cigarette smoking and alcoholism is very high, with an estimated 400,000 deaths from tobacco and 100,000 deaths from alcoholism reported annually in the United States.
The high rates of mortality from tobacco use in abstinent alcoholics have only recently come to light. Studies have shown that abstinence from alcohol essentially eliminates the premature deaths or increased mortality rates associated with active alcoholism. However, similar studies showing a reduction in mortality rates from abstinence in nicotine addiction have not been found. This is because people with a history of heavy drinking and smoking are at a higher risk of developing cancers of the head and neck. Additionally, recovering alcoholics who smoke are more likely to get heart disease, lung disease, and cancers of the head, mouth, and throat. They are also more likely to die earlier than the general population.
The relationship between smoking and drinking is such that smoking can lead to a stronger craving for alcohol. However, quitting smoking during treatment for alcoholism or immediately after can increase one's chances of staying sober. People who have quit smoking for an extended period report feeling more in control of their lives, less anxious, and less depressed than when they smoked. They also feel that their overall health has improved.

1.3 million non-smokers die from second-hand smoke
Smoking kills more people than alcohol, with over 8 million tobacco-related deaths per year worldwide, 7 million of which are a result of direct tobacco use. Around 1.3 million non-smokers die from exposure to second-hand smoke each year. This is because second-hand smoke, which fills restaurants, offices, homes, and other enclosed spaces, causes serious cardiovascular and respiratory diseases, including coronary heart disease and lung cancer. There is no safe level of exposure to second-hand smoke.
The high number of deaths from tobacco use is partly due to the addictive nature of nicotine, which is found in tobacco products. The close association between nicotine addiction and alcoholism is well established, with 80% of alcoholics smoking and 30% of smokers being alcoholics. The mortality rate from cigarette smoking and alcoholism is very high, with an estimated 400,000 deaths from tobacco and 100,000 deaths from alcoholism reported annually.
In addition to the immediate health risks, tobacco use also contributes to poverty, as it diverts household spending from basic needs such as food and shelter. This is especially true in low- and middle-income countries, where 80% of the world's 1.3 billion tobacco users reside.
While the dangers of tobacco are well-known, the risks associated with alcohol consumption are also significant. Alcohol use is a causal risk factor for over 230 disease conditions. In Canada, for example, the risk of premature death increases with the number of drinks consumed per day, with males who consume 5 drinks/day having an equivalent risk as smoking 4.9 cigarettes/day, and females who consume 5 drinks/day having an equivalent risk as smoking 4.2 cigarettes/day.
Overall, the combination of cigarette smoking and alcohol consumption poses a significant threat to public health, resulting in millions of deaths worldwide each year.

Alcohol and tobacco cause certain cancers
Alcohol and tobacco use are leading causes of cancer, with tobacco smoking being the primary cause of lung cancer. Tobacco use accounts for about 25% of all cancer deaths globally, including 30% of all cancer-related deaths. Tobacco products, including cigars, smokeless tobacco, and water pipes, are major contributors to cancer cases. The harmful chemicals in smoked tobacco, approximately 7,000 of them, alter cells in the body, leading to cancer development.
Alcohol consumption is also a causal risk factor for over 230 disease conditions, according to the three-digit International Classification of Diseases, Revision 10 (ICD-10) codes. The International Agency for Research on Cancer (IARC) classified alcohol as a Group 1 carcinogen in 1987 due to sufficient evidence linking it to cancers of the oral cavity, pharynx, larynx, oesophagus, and liver. The National Toxicology Program has listed alcoholic beverage consumption as a known human carcinogen in its Report on Carcinogens since 2000.
The risk of alcohol-related cancers is influenced by a person's genes, particularly those involved in metabolizing alcohol. For example, individuals of East Asian descent with a "superactive" form of ADH that rapidly converts alcohol to toxic acetaldehyde have a higher risk of pancreatic cancer. Additionally, women who consume just one drink per day have a higher risk of breast cancer than those who drink less than one drink per week.
The combination of alcohol and tobacco use significantly increases the risk of specific cancers. People who use both substances have a much higher risk of developing cancers of the oral cavity, pharynx, larynx, and oesophagus than those who use either substance alone. The harmful effects of alcohol and tobacco together are multiplicative, meaning the combined risk is greater than the sum of the individual risks associated with each substance.
Quitting tobacco and reducing alcohol consumption can lower the risk of cancer. According to Dr. Jon Ebbert, "It's never too late to stop. For example, after quitting cigarette smoking, the risk for cancer goes down." Similarly, Dr. Nino Berdzuli, Director of the Division of Country Health Programmes, emphasizes the need for bold policies to prevent cancer and increase public awareness about the cancer-causing effects of alcohol and tobacco.

Males who consume 5 drinks a day have an equivalent risk to smoking 4.9 cigarettes a day
Smoking and alcohol consumption are two of the most common causes of preventable deaths globally. Research has shown that smoking kills more people than alcohol, AIDS, car accidents, illegal drugs, murders, and suicides combined.
While the dangers of smoking are well-known, the risks associated with alcohol consumption are less understood by the public. To address this, studies have been conducted to quantify and communicate the risk equivalencies between alcohol and tobacco consumption in terms of mortality.
One such study from Canada found that males who consumed 5 drinks per day had an equivalent risk of premature death as smoking 4.9 cigarettes per day. It is important to note that a standard drink in Canada contains 13.45 grams of alcohol. The study also found that as alcohol consumption increased, the equivalency ratio decreased for both males and females. For example, a male who consumes 1 drink per day is equivalent to smoking 0.4 cigarettes per day.
These risk equivalencies can help individuals improve their understanding of the mortality risks associated with increased alcohol consumption. Additionally, they highlight the importance of addressing both smoking and alcohol use as significant public health concerns.
In conclusion, while smoking and alcohol consumption both pose serious health risks, the combination of these two habits can significantly increase the chances of premature death. It is crucial for individuals to be aware of these risks and make informed decisions to protect their health and well-being.
