Codeine is a commonly prescribed pain medication categorised as an opioid. It is frequently used to relieve moderate to severe pain resulting from surgeries, injuries, or chronic conditions. However, it’s important to note that codeine is highly addictive and can lead to physical dependence and withdrawal symptoms with prolonged use.
Codeine has an addictive quality because it attaches to opioid receptors in the brain, creating sensations of euphoria, relaxation, and pain relief. With prolonged use, the brain becomes accustomed to these effects, necessitating higher doses of codeine for comparable relief. This can result in dependence, where individuals rely on the drug to feel normal and prevent withdrawal symptoms.
Certain factors can elevate the risk of codeine addiction, such as a past history of substance abuse, underlying mental health conditions, and genetic predisposition. It is crucial for individuals who are prescribed codeine to strictly follow usage instructions and to possess knowledge about the potential dangers associated with addiction.

What is Codeine
Codeine is a medication classified as an opioid. It is frequently prescribed to alleviate mild to moderate pain or alleviate coughing symptoms. To achieve its effects, codeine binds with specific receptors in the brain and spinal cord associated with opioids. This interaction helps diminish the perception of pain and suppresses coughing.
You can find codeine in different forms, such as tablets, capsules, and liquids. It is commonly combined with other pain-relieving medications like paracetamol or ibuprofen to increase its effectiveness.
In the UK, codeine is considered a Schedule II controlled substance because of its high potential for abuse and addiction. Therefore, it is strictly regulated and can only be obtained with a prescription from a healthcare professional. It’s important to use codeine responsibly and under the supervision of a qualified medical provider.

Codeine is a powerful pain reliever, but it carries the risk of addiction. Continued use of codeine can lead to physical dependency, tolerance, and withdrawal symptoms when usage is discontinued. To minimize these risks, it’s crucial to use codeine strictly as prescribed and avoid prolonged usage that goes beyond what is necessary for pain management.
Understanding Addiction
The nature of codeine addiction is multifaceted and not fully comprehended. Nonetheless, certain fundamental principles can provide insights into its development.
Addiction is commonly referred to as a chronic brain disease. This condition is characterized by an overwhelming urge to seek and use drugs, even in the face of negative consequences. Experts believe that addiction arises from a complex interplay between genetics, environmental factors, and developmental influences, which collectively increase an individual’s susceptibility to addiction.
When individuals consume codeine, it triggers the brain’s reward system, causing the release of dopamine, a neurotransmitter that generates sensations of pleasure and contentment. However, with repeated use, the brain adjusts to codeine’s presence by reducing its sensitivity to dopamine. This can result in tolerance, necessitating higher doses of the drug for a similar effect to be achieved.
When a person becomes tolerant to codeine, they may experience withdrawal symptoms if they stop or reduce their dosage. These symptoms can be quite uncomfortable and might include anxiety, restlessness, muscle aches, and difficulty sleeping. To avoid these unpleasant symptoms, individuals may continue taking codeine even when they no longer desire to do so.
Addiction includes more than just tolerance and withdrawal. It also involves alterations in the brain’s reward system, which can make it challenging for individuals to quit using codeine, despite their desire to do so. These changes can result in powerful cravings for the drug, often triggered by environmental cues that are linked to drug use—such as seeing a pill bottle or smelling a pharmacy.
Addiction is a complex issue, influenced by various biological, psychological, and social factors. While the exact mechanisms behind codeine addiction are not fully comprehended, it is evident that it can have severe and enduring effects on individuals facing this struggle.
How Codeine Affects the Brain
Codeine is a type of opioid medication commonly used to alleviate pain. It functions by attaching to specific receptors in the brain that suppress pain signals. Nonetheless, codeine can also induce sensations of euphoria and relaxation, which can potentially lead to addiction.
Once codeine reaches the brain, it undergoes a conversion process and transforms into morphine, which is a stronger opioid. The morphine then attaches itself to mu-opioid receptors in the brain. These receptors play a crucial role in managing pain, reward, and pleasure. Consequently, this attachment activates dopamine release – a neurotransmitter closely associated with feelings of pleasure and reward.
Codeine use can cause a release of dopamine in the brain, resulting in feelings of euphoria and relaxation. When taken regularly, the brain may become reliant on this dopamine surge, leading to addiction.

Codeine not only impacts dopamine levels but also influences other important brain chemicals like serotonin and norepinephrine. These neurotransmitters play a crucial role in regulating mood, sleep, and anxiety. Consequently, codeine usage can disturb the delicate balance of these neurotransmitters, resulting in alterations in mood and behavior.
The effects of codeine on the brain can be both intricate and widespread. While it can effectively alleviate pain, it also carries a high risk for addiction. Gaining an understanding of how codeine impacts the brain is crucial in efforts to prevent and address addiction.
Physical Dependence on Codeine
Codeine is an opioid medication that can lead to physical dependence in individuals. Physical dependence occurs when the body becomes accustomed to having codeine present and relies on it to function normally. If codeine is suddenly stopped, withdrawal symptoms may arise.
Withdrawal symptoms from codeine can include:
- Nausea and vomiting
- Diarrhoea
- Sweating
- Tremors
- Muscle aches and pains
- Insomnia
- Anxiety
The intensity of withdrawal symptoms can vary based on how long and how frequently codeine was used. These symptoms typically start within a few hours after the last dose of codeine and can persist for multiple days.
Continuously using codeine can result in tolerance, where larger amounts of the drug are needed to produce the same effects. This can be dangerous because it raises the risk of an overdose, as individuals might consume higher doses of codeine to achieve their desired results.
It’s crucial to differentiate between physical dependence on codeine and addiction. Physical dependence is a biological response to the drug, while addiction involves psychological and behavioral aspects. However, physical dependence can contribute to the development of addiction because individuals may continue using codeine to avoid experiencing withdrawal symptoms.
Psychological Dependence on Codeine
Many people who misuse codeine develop a psychological dependence on the drug. This means that they form a strong emotional connection to it and experience intense cravings for its effects.
Codeine acts by attaching to opioid receptors in the brain, triggering sensations of pleasure and euphoria. With prolonged use, the brain becomes dependent on these sensations, leading individuals to believe they require the drug to maintain regularity.
Alongside its physical effects, codeine can also have psychological impacts. The drug often induces feelings of relaxation and tranquility, making it an attractive option for individuals dealing with anxiety or stress. Consequently, some people turn to codeine as a form of self-medication, ultimately leading to psychological dependence.
Additionally, individuals who misuse codeine may encounter withdrawal symptoms when they attempt to cease its use. These symptoms can encompass anxiety, depression, difficulty sleeping, and irritability. The apprehension of facing these symptoms may create psychological dependence and hinder individuals from discontinuing their drug use.
In summary, those who abuse codeine can develop a strong psychological dependency on the drug. They may experience intense cravings and emotional attachment that make quitting challenging. It is crucial for individuals dealing with codeine addiction to reach out for professional assistance and support.
