Am I Addicted to Caffeine? Signs & Symptoms

Although caffeine addiction may seem like a playful joke, caffeine dependence is a real issue that many people face. Learn how it is treated.

Caffeine is amild stimulantthat is often contained in tea, coffee, carbonated beverages and energy foods and drinks. It is consumed by many people in varying quantities and is thought of as the most commonly used psychoactive drug worldwide. Based on surveydata published in 2014, about 85% of the U.S. population drank at least one caffeinated beverage every day. There is some debate as to whether true addiction to caffeine is possible. It is certainly true that people can become physicallydependenton caffeine, since mildwithdrawal may occurwhen use is stopped.Caffeine may also cause certain symptoms(psychological and behavioral) similar to other addictive processes.

Many people use caffeine due to its stimulant properties since it can help with mental alertness and reaction time. Some research has shown that people who use caffeine regularly have less depression. Caffeine is also appealing because it can help with exercise performance and increase metabolic rate.

How Addictive Is Caffeine?

Although caffeine is a mild stimulant, it does not have the same addiction potential as more potent stimulant substances. In fact, many addiction experts disagree as to whether true caffeine addiction is possible. One definition ofsubstance addictiondescribes continued substance use despite negative consequences. People who use caffeine heavily often do not notice negative consequences in their lives, and it is unlikely that caffeine use causes serious harm in any way.

Many well-known addictivesubstances cause increases in the brain chemicalcalled dopamine. Dopamine is involved in the reward circuit within the brain and is thought to be a major contributor in various substance use disorders. Although caffeine use may cause a small rise in dopamine levels, it probably does not cause a large enough increase to upset the dopamine balance substantially. Also, since the adverse effects of high caffeine use (like agitation and fidgeting) are uncomfortable for many people, most people do not use extreme amounts of caffeine.

There is currently not enough research to determine whethercaffeine use disordershould be an official psychological diagnosis, mostly because the relative harm related to caffeine use is difficult to define.

Caffeine is known to be associated with physical and psychological dependence, however. Many people feel like they have trouble functioning without their morning cup of coffee. Caffeinewithdrawal symptomsdo exist, and they include many symptoms including headache, fatigue and decreased alertness.

How Long Does it Take to Get Addicted to Caffeine?
