Alcohol is a central nervous system depressant, but when consumed, it initially acts as a stimulant. Alcohol triggers the brain to release dopamine, a neurotransmitter that provides energy, stimulation, and good feelings. This release of dopamine induces feelings of pleasure, increased sociability, and heightened confidence. However, as one continues to drink and the blood alcohol concentration (BAC) rises, the depressant effects of alcohol start to dominate, leading to sedation, impaired judgment, slowed reaction times, and decreased motor coordination. The extent of alcohol's effects depends on various factors, including the amount consumed, speed of consumption, tolerance, physical condition, age, gender, weight, and overall health.

What You'll Learn
Depressant
Alcohol is a central nervous system (CNS) depressant, meaning it slows down brain activity and neural activity. Alcohol is a psychotropic depressant, inhibiting neurons by impacting their ability to transmit impulses. This results in decreased brain activity, with a lag in processing that slows down alertness, balance, movement, and the ability to think.
Alcohol affects the brain's neurotransmitters, which are responsible for carrying messages to neurons. Alcohol binds to certain neurotransmitters, causing them to slow down. This includes the suppression of glutamate, an excitatory neurotransmitter that increases brain activity. Conversely, alcohol enhances the effects of the inhibitory neurotransmitter GABA, which decreases brain activity to calm and slow down the body.
The amount of alcohol consumed determines the type of effect experienced. Initially, alcohol acts as a stimulant, with drinkers experiencing a boost in energy and euphoria. However, as more alcohol is consumed, depressant effects develop. These effects include cognitive impairment, slurred speech, unsteady movement, disturbed perceptions, and an inability to react quickly. Alcohol impairs judgment, vision, and alertness, dulls the senses, affects concentration, and slows reaction time.
Alcohol can also induce negative mental health effects, such as anxiety and depression. While alcohol may initially reduce anxiety, the chemical changes in the brain can soon lead to negative feelings. Alcohol affects the brain's neurotransmitters, reducing the number of neurotransmitters over time. This can result in feelings of depression and anxiety, as the brain becomes dependent on alcohol to produce dopamine and serotonin.
The use of depressants, including alcohol, can lead to dependence and tolerance. People may develop a psychological or physical dependence, craving depressants and prioritising their use over other activities. Withdrawal from depressants can be challenging, with symptoms varying from person to person. It is important to seek professional help when dealing with alcohol or depressant dependence.

Stimulant
Alcohol is a central nervous system depressant, meaning it slows down communication between the brain and body. However, it does have some initial stimulant-like properties. When consumed, alcohol initially acts as a central nervous system depressant by slowing down brain activity and functions such as speech, reactions, and movement. It also affects brain function and neural activity, impairing the ability to think clearly, altering perceptions of one's immediate surroundings, and distorting issues of judgment.
In lower doses, alcohol can have an uplifting, stimulating effect, inducing feelings of pleasure, increased sociability, and heightened confidence. It acts as a stimulant by reducing inhibitions and producing a sense of euphoria. This is caused by a release of dopamine in the brain. Dopamine is the "happy hormone" responsible for good moods, pleasure, and motivation. It increases alertness, boosts energy, and can induce impulsive behaviour.
The effects of alcohol on the human body and mind can be described as a biphasic response, meaning it has two distinct phases. The first phase is stimulating, and the second phase is depressive. The depressive effects of alcohol start to dominate once the blood alcohol concentration (BAC) reaches about 0.08 mg/l. The shift from stimulation to depression is the very essence of the biphasic curve.
The effects of alcohol vary greatly by individual and are influenced by a number of factors, including body chemistry, sex, weight, alcohol tolerance, and the dose of alcohol consumed. Females and males generally process alcohol at different rates.

Carcinogen
Alcohol consumption is associated with an increased risk of cancer. The International Agency for Research on Cancer (IARC) classified alcohol as a Group 1 carcinogen in 1987 or 1988, placing it in the highest-risk category alongside asbestos, radiation, and tobacco. This classification is based on substantial evidence linking alcohol consumption to cancers of the oral cavity, pharynx, larynx, esophagus, and liver. Epidemiological studies have consistently shown that alcohol drinkers have a higher risk of these cancers compared to non-drinkers, and that the risk increases with the amount of alcohol consumed.
The carcinogenic effects of alcohol are primarily attributed to its metabolic breakdown products and their impact on the body. Ethanol, the chemical name for alcohol, is converted by enzymes into a highly toxic metabolite called acetaldehyde. This conversion primarily occurs in the liver, but recent studies suggest it also happens in the oral cavity, influenced by factors like the oral microbiome. Acetaldehyde is a probable human carcinogen, capable of damaging DNA and proteins. It is formed in the liver and is highly carcinogenic, contributing to both local (mouth, throat, esophageal cancers) and distant (skin, liver, breast) cancers.
Additionally, acetaldehyde can lead to the generation of reactive oxygen species, which can further damage DNA, proteins, and lipids through oxidation. Alcohol consumption can also impair the body's ability to absorb essential nutrients associated with cancer risk, such as vitamins A, C, D, and E, as well as carotenoids and the vitamin B complex, including folate. This impairment in nutrient absorption can have detrimental effects on overall health and increase cancer susceptibility.
The risk of cancer associated with alcohol consumption is particularly prominent in tissues that come into direct contact with alcohol upon ingestion, such as the oral cavity, pharynx, and esophagus. This is due to the cytotoxic effects of ethanol, which cause cell death and trigger the division of stem cells to replace the damaged cells. With each division, stem cells become vulnerable to mutations and chromosomal alterations, increasing the likelihood of carcinogenesis.
Furthermore, alcohol consumption can lead to changes in hormone levels, such as increased estrogen and insulin. These hormones act as chemical messengers, and elevated levels can stimulate cell division, thereby enhancing the potential for cancer development. Alcohol also acts as an irritant in the mouth and throat, making it easier for cells in these areas to absorb harmful chemicals that contribute to cellular damage and increase the risk of cancer.

Neurotoxin
Alcohol is a neurotoxin, meaning it is toxic to the brain and nervous system. It can disrupt communication pathways in the brain, affecting the way the brain looks and works. This disruption can change mood and behaviour and make it harder to think clearly, move with coordination, and control balance. It can also cause numbness in the hands and feet.
The neural effects of alcohol consumption can lead to cognitive and physical decline. Alcohol interferes with the brain's communication pathways by slowing neural communication between the brain and body. This interference can cause gaps in memory, known as blackouts, and can also lead to amnesia, lethargy, confusion, loss of sensation, and difficulty breathing.
Alcohol is particularly dangerous to the developing brain during pregnancy, causing congenital disabilities and developmental disorders. It can also alter brain development in adolescents, potentially resulting in long-lasting changes in brain structure and function.
Chronic and heavy alcohol consumption can lead to permanent brain damage, including a decrease in overall brain volume and disruptions to the normal functioning of brain regions. This is caused by neuroinflammation, which releases cytotoxic molecules and compounds that kill neurons and their connections. Alcohol also increases oxidative stress, which damages the proteins, lipids, and DNA that make up neural cell membranes.
The peripheral nervous system is also affected by alcohol, with alcohol misuse linked to peripheral neuropathy, a condition that causes numbness in the arms and legs and painful burning in the feet. Alcohol-related nerve damage may also cause heart arrhythmias, postural hypotension, diarrhoea, and erectile dysfunction.

Diuretic
Alcohol is a diuretic, meaning it increases urine production. When alcohol is consumed, it inhibits the release of an antidiuretic hormone called vasopressin, also known as the antidiuretic hormone (ADH). Without this hormone, the bladder fills up more rapidly, causing frequent urination.
A 2017 study found that four alcoholic beverages can make an individual urinate 600 to 1,000 mL of fluid in just a few hours. The diuretic effect of alcohol can last up to four hours, but this depends on the type of alcoholic beverage consumed. For instance, a 2010 study found that stronger alcoholic drinks, such as wine and spirits, resulted in a higher urine output compared to non-alcoholic counterparts. However, another 2010 study found that there was no difference in urine output between alcoholic and non-alcoholic beer when the body was hypohydrated.
The diuretic effect of alcohol primarily affects the body's water balance, increasing the risk of dehydration. This is particularly true for older adults, who are at a higher risk of dehydration due to physiological changes associated with ageing. To mitigate dehydration, it is recommended to drink plenty of water before, during, and after consuming alcohol.
In addition to increasing urine production, alcohol consumption can also lead to excessive urination by weakening the muscles that control the bladder. This can result in bedwetting, especially in adults with incontinence issues. Regular alcohol consumption can also increase the risk of kidney disease or damage, even without excessive drinking.
