Alcohol is a toxic, psychoactive, and dependence-producing substance that affects everyone differently. While some studies have suggested that light-to-moderate alcohol intake may be associated with certain health benefits, such as a reduced risk of cardiovascular disease, the World Health Organization (WHO) has stated that there is no safe level of alcohol consumption. The more you drink, the more harmful it is, and even low levels of alcohol intake have been linked to various health risks, including an increased risk of cancer, muscle wasting, gout, and damage to the gastrointestinal tract and peripheral nervous system. Therefore, when discussing alcohol intake, it is essential to consider the potential risks and harms associated with drinking.

What You'll Learn
Alcohol is a toxic, psychoactive, and dependence-producing substance
Alcohol is a toxic substance that can cause harm to the human body. It is classified as a Group 1 carcinogen by the International Agency for Research on Cancer, alongside asbestos, radiation, and tobacco. The toxic effects of alcohol are mediated by its carcinogenic byproduct acetaldehyde, which is produced when ethanol (the alcohol found in beverages) breaks down in the body. This means that any beverage containing alcohol, regardless of its price or quality, poses a risk of developing cancer. In addition to cancer, excessive alcohol consumption is associated with various diseases and injuries, including liver disease, cardiovascular disease, and alcohol poisoning, which can be life-threatening.
Alcohol is also a psychoactive substance, which means it interacts with the central nervous system and alters brain function. The effects of alcohol on the brain can include lowered inhibitions, impaired judgment, and changes in sleep and memory. While small doses of ethanol can produce feelings of euphoria and relaxation, heavier consumption can lead to negative consequences such as risky behaviours, accidents, and falls. Additionally, the combination of alcohol with other substances, such as caffeine or cocaine, can increase the craving for more alcohol and have harmful interactions.
Alcohol is well-known for its dependence-producing properties, and alcohol use disorder is a recognised condition. The development of dependence can vary among individuals, with some becoming dependent more quickly than others. Alcohol dependence can lead to withdrawal symptoms upon cessation of alcohol consumption, including anxiety, restlessness, insomnia, tremors, and seizures. The management of alcohol withdrawal often involves the use of benzodiazepines, which can help reduce these symptoms. However, benzodiazepines themselves can also have abuse liability and may not be suitable for all patients.
The World Health Organization (WHO) has stated that there is no safe level of alcohol consumption when it comes to health. The risk of harm from alcohol starts from the first drop of any alcoholic beverage and increases with the amount consumed. The impact of alcohol consumption is influenced by various factors, including frequency of drinking, age, sex, and health status. While some individuals may adopt lower-risk drinking patterns, societal factors such as cultural norms and the availability of alcohol can also play a role in drinking habits and related problems.
In summary, alcohol is a toxic, psychoactive, and dependence-producing substance that poses significant health risks. The harmful effects of alcohol are well-documented, and global initiatives, such as the WHO's Global Alcohol Action Plan 2022-2030, aim to reduce the harmful use of alcohol through evidence-based strategies. It is important for individuals to be aware of the risks associated with alcohol consumption and to seek help if they suspect they have an alcohol problem.

Alcohol affects men and women differently
Women are also more vulnerable to the effects of alcohol on a psychological level. They are more likely to experience mood and behavioural changes, blackouts, and addiction. Research suggests that women are more susceptible to alcohol-induced liver inflammation, cardiovascular disease, memory blackouts, hangovers, and certain cancers. Women may also experience higher rates of depression and anxiety, and are more likely to drink in response to negative emotions and problems with loved ones.
The differences in the effects of alcohol on men and women also have social implications. Alcohol use disorder (AUD) is characterised by symptoms such as excessive time spent drinking, needing to drink more to get the same effect, and the inability to stop drinking despite negative consequences. Problem drinking among women increased by 83% from 2002 to 2013, closing the gender gap that had previously existed. Currently, 5.4 million women over 18 may be considered to have AUD and require treatment. However, due to the stigma of addiction and feelings of guilt or shame, less than 10% of women seek formal help.
While there is evidence that moderate drinking may have some health benefits for both men and women, it is important to note that the risks associated with alcohol consumption outweigh these potential benefits. Alcohol is a toxic, psychoactive, and dependence-producing substance, classified as a Group 1 carcinogen. It contributes to numerous diseases and injuries, including at least seven types of cancer. Therefore, it is crucial to consume alcohol in moderation and be aware of the potential risks involved.

Alcohol can cause peripheral neuropathy
Alcoholic neuropathy, or alcohol-related neuropathy, is a condition caused by consuming large amounts of alcohol over a long period. Alcoholic neuropathy is damage to the nerves that results from excessive drinking. The peripheral nervous system includes all peripheral nerves, which transmit signals between the body, spinal cord, and brain. Peripheral nerves help the body manage important sensory and motor functions.
The exact cause of alcoholic neuropathy is unknown, but it likely includes both a direct poisoning of the nerve by alcohol and the effect of poor nutrition associated with alcoholism. Nutritional deficiencies and alcohol metabolism's direct toxic effects on neurons are also thought to be causes. Alcohol can be toxic to nerve tissue, and people who drink too much may start to feel pain and tingling in their limbs. This is known as alcoholic neuropathy. Up to half of long-term heavy alcohol users develop this condition, and studies have shown that up to 66% of patients with chronic alcohol use disorder may have some form of the disease.
The condition commonly presents with pain, paresthesias, and ataxia in the distal lower extremities. Severe alcoholic neuropathy may cause permanent nerve damage and can affect the upper body and the function of some organs. Alcohol-related neuropathy can damage the nerves involved in movement, which may affect muscles and cause weakness and cramping.
Treatment should be focused on alcohol sobriety and the replacement of key nutrients such as thiamine, folate, and vitamin B12. Abstaining from alcohol can help restore nutritional health, improve symptoms, and prevent further nerve damage. However, some alcohol-induced nerve damage is permanent, and residual neuropathy is common even in patients who quit alcohol.

Alcohol can increase the risk of colorectal cancer
Alcohol is a toxic, psychoactive, and dependence-producing substance. It has been classified as a Group 1 carcinogen, which is the highest-risk group, also including asbestos, radiation, and tobacco. Ethanol (alcohol) causes cancer through biological mechanisms as the compound breaks down in the body. This means that any beverage containing alcohol poses a risk of developing cancer.
Alcohol use is one of the most important preventable risk factors for cancer, along with tobacco use and excess body weight. Alcohol use accounts for about 5% of all cancers and 4% of all cancer deaths in the United States. However, many people are unaware of the link between alcohol and cancer. Drinking alcohol is associated with an increased risk of developing numerous cancers, including colorectal cancer.
Colorectal cancer develops in the large intestines or rectum. The breakdown of ethanol by the gastrointestinal tract can generate toxic substances like acetaldehyde, which can damage the DNA of cells in the colon and rectum. This damage can cause cells to replicate uncontrollably and form a tumor. Ethanol may also cause changes to the gut's microbiome, leading to bowel inflammation and possibly activating enzymes that make an individual more prone to developing cancer.
Research has found that people with alcohol use disorder have a significantly higher chance of developing colorectal cancer than those without the disorder. The risk increases with the duration of alcohol use disorder. Additionally, studies have shown that stopping alcohol consumption is associated with lower risks of colorectal cancer. It may take years for the risks of cancer to return to the level of non-drinkers, but it is never too late to stop drinking and reduce the risks.
In summary, alcohol consumption, even in moderate quantities, can increase the risk of colorectal cancer. The risk increases with the amount and duration of alcohol consumption. Therefore, reducing alcohol intake or abstaining from alcohol can be an important step in lowering the chances of developing colorectal cancer.

Alcohol can be safely managed with benzodiazepines
Alcohol and benzodiazepines should not be mixed under any circumstances. The concurrent use of alcohol and benzodiazepines can be extremely dangerous, as the two interact with the body in similar ways. Both substances are central nervous system (CNS) depressants, and when combined, they can have compounding effects on the body's CNS, which regulates vital bodily functions like breathing.
The effects of combining alcohol and benzodiazepines can be unpredictable and include enhanced risks of injury, falls, driving accidents, violence, risky sexual behavior, and increased risk of alcohol or substance use disorders. The combination may also lead to drowsiness, impaired motor control, unusual behavior, memory problems, disinhibition, amnesia, and sedation, including a severe loss of motor function and altered mental status. Furthermore, the synergistic depressant effects of alcohol and benzodiazepines on the CNS can result in respiratory depression, which can have life-threatening consequences.
While benzodiazepines have been safely used for years to manage acute alcohol withdrawal, this should be done under strict medical supervision. Benzodiazepines are often used to reduce anxiety, restlessness, insomnia, tremors, and withdrawal seizures associated with alcohol withdrawal. However, they come with a risk of abuse and dependency, and individuals should seek professional medical attention when discontinuing their use.
In conclusion, while benzodiazepines can be an effective tool in managing alcohol withdrawal symptoms, they should never be consumed concurrently with alcohol due to the severe and potentially life-threatening risks involved.
