What is addiction?
Addiction is a psychological and physical inability to stop consuming a chemical, drug, activity, or substance, even though it is causing psychological and physical harm.
The term addiction does not only refer to dependence on substances such as heroin or cocaine. A person who cannot stop taking a particular drug or chemical has a substance dependence. Some addictions also involve an inability to stop partaking in activities, such as gambling, eating, or working. In these circumstances, a person has a behavioral addiction.
Addiction is a chronic disease that can also result from taking medications. The overuse of prescribed opioid painkillers, for example, causes 115 deaths every day in the United States. When a person experiences addiction, they cannot control how they use a substance or partake in an activity, and they become dependent on it to cope with daily life.
Every year, addiction to alcohol, tobacco, illicit drugs, and prescription opioids costs the U.S. economy upward of $740 billion in treatment costs, lost work, and the effects of crime. Most people start using a drug or first engage in an activity voluntarily. However, addiction can take over and reduce self-control.
Addiction vs. misuse
Drug addiction and drug misuse are different.
Misuse refers to the incorrect, excessive, or non-therapeutic use of body- and mind-altering substances.
However, not everybody that misuses a substance has an addiction. Addiction is the long-term inability to moderate or cease intake.
For example, a person who drinks alcohol heavily on a night out may experience both the euphoric and harmful effects of the substance.
However, this does not qualify as an addiction until the person feels the need to consume this amount of alcohol regularly, alone, or at times of day when the alcohol will likely impair regular activities, such as in the morning.
A person who has not yet developed an addiction may be put off further use by the harmful side effects of substance abuse. For example, vomiting or waking up with a hangover after drinking too much alcohol may deter some people from drinking that amount anytime soon.
Someone with an addiction will continue to misuse the substance in spite of the harmful effects.
The primary indications of addiction are:
uncontrollably seeking drugs
uncontrollably engaging in harmful levels of habit-forming behavior
neglecting or losing interest in activities that do not involve the harmful substance or behavior
relationship difficulties, which often involve lashing out at people who identify the dependency
an inability to stop using a drug, though it may be causing health problems or personal problems, such as issues with employment or relationships
hiding substances or behaviors and otherwise exercising secrecy, for example, by refusing to explain injuries that occurred while under the influence
profound changes in appearance, including a noticeable abandonment of hygiene
increased risk-taking, both to access the substance or activity and while using it or engaging in it
When a person has an addiction, and they stop taking the substance or engaging in the behavior, they may experience certain symptoms.
These symptoms include:
tremors and shaking
a loss of appetite
If a person has regularly used alcohol or benzodiazepines, and they stop suddenly or without medical supervision, withdrawal can be fatal.
Medicinal advances and progress in diagnosing have helped the medical community develop various ways to manage and resolve addiction. Methods include:
behavioral therapy and counseling
medication and drug-based treatment
medical devices to treat withdrawal
treating related psychological factors, such as depression
ongoing care to reduce the risk of relapse
