Cross-addiction - definition, types

Cross-addiction often appears at the moment when one form of addiction begins to lead to the emergence of another. A person limiting drugs may reach for alcohol, and someone giving up drugs – start drinking more often. Such combinations not only intensify the effect of each substance, but also increase the risk of serious health complications. Knowledge on this subject is particularly important for addicted people and their environment. Familiarity with potential risk can help eliminate the threat of falling into another addiction.

What addictions are there? List and classification

Addictions can be divided into two main categories – chemical and behavioral. Chemical addictions result from dependence on psychoactive substances that change brain function and lead to the development of tolerance and withdrawal symptoms. The most common include:

• alcoholism

• drug addiction (e.g., amphetamine, cocaine, methamphetamine – so-called "crystal")

• medication addiction (including sedatives, sleeping pills, painkillers)

• nicotine addiction

• abuse of doping agents and other synthetic psychoactive substances.

Behavioral addictions concern established behavior patterns that provide strong emotional or mental stimulation. These may include:

• gambling

• computer, internet, and social media addiction

• compulsive shopping (shopping addiction)

• sex or pornography addiction

What is cross-addiction?

Cross-addiction is a phenomenon in which a person addicted to one substance or behavior gradually develops dependence on another, often with a similar mechanism of action. An example can be a situation when a person gives up alcohol but starts using drugs, or stops stimulants and reaches for sedatives. Typical combinations include alcohol and drugs. Behavioral addictions can increase the risk of cross-addictions, because they activate the same brain areas as psychoactive substances. A person addicted to gambling or games may be more susceptible to reaching for alcohol, drugs, or medications to intensify emotions or alleviate tension. In this way, behavioral addiction can become a starting point for chemical addiction and vice versa.

Mechanism of action of cross-addiction

Cross-addiction is based on biological and psychological connections that make a person particularly susceptible to reaching for other substances acting in a similar way. On a biological level, the main role is played by the reward system in the brain, that is, structures responsible for experiencing pleasure and motivation. Psychoactive substances, regardless of type, stimulate dopamine release, which causes the brain to learn to respond with strong desire to stimuli associated with euphoria or relief. The brain easily transitions from one substance to another, because different psychoactive substances can stimulate the same neural areas. For an addicted person, this means that interrupting contact with one substance does not remove the problem. Addiction mechanisms remain active, and the need to stimulate the reward system can be satisfied by another substance. Therefore, combinations such as alcohol and drugs are particularly risky – they facilitate the entrenchment of addictive patterns and lead to faster deepening of addiction.

Alcohol and drugs – exceptionally harmful mixed addiction

The combination of alcohol with drugs is one of the most dangerous variants of mixed addiction. Alcohol acts depressively on the central nervous system, while many drugs act stimulantly or hallucinogenically. Such a mixture disrupts heart function, breathing, thermoregulation, and motor coordination, while weakening behavioral control, increasing the risk of accidents, violence, or overdose. The body is forced to simultaneously fight many toxins, which burdens the liver, kidneys, and nervous system significantly more than in the case of one substance.

Amphetamine and alcohol – how these substances mutually affect the body

Amphetamine strongly stimulates the nervous system, raises blood pressure, and accelerates heart function. Alcohol, on the other hand, acts inhibitingly, but initially can cause an effect of euphoria and relaxation. The combination of these substances masks signs of alcohol intoxication, whereby a person under the influence of amphetamine can drink significantly more without feeling drunk. This increases the risk of alcohol poisoning, dehydration, stroke, and heart rhythm disorders.

Cocaine and alcohol – double risk

Simultaneous use of cocaine and alcohol leads in the body to the production of cocaethylene – a toxic chemical compound that acts stronger than cocaine itself and has a longer retention time in the blood. Cocaethylene intensifies euphoria, but simultaneously significantly increases the risk of liver damage, arrhythmia, heart attack, or sudden cardiac death. Long-term combination of these substances accelerates degradation of the nervous system and causes addiction in a shorter time.

Crystal and alcohol – consequences for the nervous system

"Crystal," that is methamphetamine, is a strong stimulant that causes a sudden increase in dopamine level, as well as intense psychomotor agitation. In combination with alcohol, there is enormous burden on the nervous system. Blood pressure spikes, heart rhythm disorders, paranoid states appear, and in extreme cases acute psychoses. Alcohol additionally weakens impulse control, which in combination with aggressive agitation after methamphetamine can lead to dangerous behavior and permanent brain damage.

Treatment and therapy of cross-addictions

Effective therapy of cross-addictions requires a holistic approach. If treatment covers only alcohol, and the patient still uses drugs or medications, addiction mechanisms will remain active and the risk of relapse will be very high. Therefore, diagnosis should take into account the full picture of substances used and behaviors. The first stage of treatment is often detoxification, that is, medically controlled cleansing of the body from toxins. This process helps alleviate withdrawal symptoms, stabilize the patient's physical condition, and prepare them for further therapy. Detox alone is not enough. Psychotherapy is very important, which allows understanding addiction, learning to cope without substances or addictive activities, and avoiding situations that trigger relapse. In the case of cross-addictions, psychological therapy must cover all substances and addictive behaviors, even if the patient believes that the problem concerns only one of them.

How to minimize the risk of transition from one addiction to another

Cross-addictions consist in transferring the addiction mechanism from one substance or behavior to others, often with similar action on the brain. They can cover both chemical substances and behavioral addictions. To minimize the risk of such transition, comprehensive treatment covering all addictions is important, avoiding substances with similar action, constant therapeutic support, control of relapse signals, as well as building healthy habits and relationships. Awareness of the addiction mechanism and work on high-risk behaviors allow maintaining lasting sobriety.
