These triggers set off biochemical changes in a person’s brain that strongly influence addictive behavior. The difference between addiction and dependence can be difficult to understand. Some organizations have different definitions, use the words interchangeably or even abandon both terms altogether. (Substance use disorder, or SUD, is a preferred term in the scientific community.) Because of this lack of consistency, some ground rules can help differentiate between the two terms.
- By Buddy TBuddy T is a writer and founding member of the Online Al-Anon Outreach Committee with decades of experience writing about alcoholism.
- Physical dependence is a natural expected physiological response to drugs such as opioids, benzodiazepines, antidepressants, stimulants, and corticosteroids.
- These symptoms, including withdrawal, define physical dependence, which can occur even with short-term use in some cases.
- As substance abuse becomes more frequent, the likelihood of developing a dependence disorder becomes greater.
- Even the people who dedicate their lives to researching addiction, and who are responsible for the very medical texts that we use to diagnose addiction, haven’t been able to arrive at a clear consensus about which terms should be used.
Mental Dependence Vs. Physical Dependence
He currently serves on the National Education Goals Panel Resource Group on Safe and Drug Free Schools and was a member of the Committee on Prevention of Mental Disorders of the Institute of Medicine at the National Academy of Sciences. Long-term inpatient treatment programs vary in length, but typically last between 3 to 18 months. This type of rehab is best suited to individuals with long-term chronic addictions, especially those who have co-occurring mental health issues. Depending on the severity of the addiction, long-term treatment may be a good option, especially as many programs address the underlying emotional causes of one’s drug abuse.
What causes physical drug dependence?
- However, these recent changes mean that “dependence” now includes both physical and physiological dependence (in terms of tolerance and withdrawal symptoms).
- After a careful vote, “addiction” was changed to “substance dependence” and it remained that way until the DSM entered its 5th edition in 2013.
- At the same time, the distinction between addiction and dependence is not trivial.
- Smith and Farah (2011) reported findings from both amphetamine and methylphenidate that appeared mixed, with no indication that types of task influenced results; however, studies with significant findings also resulted in small to large effects.
- Alcohol abuse was defined as a condition in which a person continues to drink despite recurrent social, interpersonal, health, or legal problems as a result of their alcohol use.
- It is important to note, however, that differential effects may exist based on type of attention.
Alcohol abuse refers to continuing to use alcohol, often excessively, even though it creates problems in a person’s life, including health, relationship, and work-related consequences. However, the study did find that people who engaged in binge drinking more often were also more likely to be alcohol dependent. Some people inherit a genetic predisposition to be more sensitive to certain substances, and factors like age and developmental stage can make us more vulnerable. It can occur even with prescribed medications when used as addiction vs dependence directed and doesn’t necessarily signify a loss of control.
Determining Whether You’re Dependent or Addicted
Among youths, however, the rates of use are about the same for the three groups. The extent of the impact of substance abuse on U.S. society calls for a review of federal intervention efforts, whether at the level of supply reduction, treatment, or prevention. The purpose of this paper, however, is not to analyze the federal response to substance abuse, but to provide background information for those interested in understanding the scope of the problem. We know opioids, for example, can be highly addictive, and that addiction can develop quickly. They deliver a double punch — they don’t just increase the feel-good dopamine in the brain, but there’s also a need to take them consistently to avoid painful withdrawal symptoms. The term “addiction” has been somewhat controversial history over the years.
History of the Terms Dependence and Addiction
- Indeed, significant but small effects of amphetamine and methylphenidate were supported for working memory in Ilieva et al.’s (2015) meta-analytic study.
- Addiction or substance use disorder occurs when individuals are largely unable to function without the drug.
- Specifically, studies with low doses, which also exclusively included studies with male participants only and retention of memory assessed at greater intervals, demonstrated the greatest effects (Ilieva et al., 2015).
- Addiction involves a powerful psychological component that drives individuals to continue using substances or engaging in behaviors despite the detrimental effects on their health, relationships, and daily life.
- Educate yourselves about addiction, offer unwavering support, and encourage your loved ones to seek professional help.
- To confuse matters further, “substance dependence” was then changed to “substance use disorder” in the new DSM-5.
As noted previously, preliminary studies suggest prescription stimulants may proffer modest effects for cognitive neuroenhancement in adults in general; however, additional, double-blind, placebo-controlled studies are needed to adequately address this issue with healthy controls. In addition, future studies are needed to elucidate whether and how baseline cognitive functioning, genetic factors, timing of medication ingestion relative to assessment of performance, medication doses, medication formulations, and different tasks moderate the effects of stimulants on performance. Alternatively, society may choose to embrace “cosmetic” psychopharmacology due to the small, but significant cognitive effects found across multiple cognitive domains (Greely et al., 2008; Kramer, P., 1993; Marraccini et al., under review; Sahakian & Morein-Zamir, 2007). Proponents of this approach maintain that allowing anyone (medically supervised) access to these medications, regardless of ADHD status, may ultimately allow humans to reach their maximum cognitive potential (Dubljević, 2013; Greely, 2013).
Speak with your doctor if you have become physically dependent on a medication or other substance. Speak with your doctor if you develop a tolerance to your medication or any other substance. If you are taking a prescription medication, your doctor may change the class of medication, which may affect your body in a different way. If it is not a prescription medication, your doctor may be able to help you reduce your use of the substance with the least side effects. The National Center for Drug Abuse Statistics says more than 20 million people over the age of 12 in the United States have substance use disorder.
If the person’s healthcare provider determines that their substance use is problematic and they have substance use disorder, they may require treatment. While tolerance is observable during active drug use, withdrawal symptoms become evident in the hours or days following cessation. By slowly reducing the dose, patients can minimize withdrawal symptoms and ease the transition off the medication. Many symptoms can be managed at home, but moderate to severe withdrawal should be supervised by a healthcare professional and may require inpatient treatment.
The session will address treatment for substance abuse in broad terms, including some of the trends in pharmacological research that are showing promise, and discuss the latest information on what can work in terms of prevention. Drug abuse and addiction (now more commonly known as “substance use disorder” or “problematic substance use”) have led to a major health crisis in the U.S. Not only are millions of Americans struggling with substance use disorder, but in 2014 alone, there were more than 45,000 overdose deaths, over half of which involved prescription opioids and heroin. Alcohol abuse is also a continuing problem in the country, with over 65 million people binge drinking in the past month. Today, the APA classifies substance use disorders as mild, moderate, or severe. It doesn’t use the terms abuse and dependence to categorize the severity of an addiction.
Medically, and in practice, addiction is most often diagnosed using the DSM-5 category of substance use disorder. Unhelpfully, however, nowhere in the DSM-5 is this explicitly and transparently mentioned. In fact, the American Psychiatric Association (APA), who are the developers of the DSM, nonchalantly utilize the terms “substance use disorder” and “addiction” interchangeably on their website. One of the main medical texts that are used by mental health professionals to diagnose addiction is the Diagnostic and Statistical Manual of Mental Disorders (the DSM), which is currently in its fifth edition. Our state-specific resource guides offer a comprehensive overview of drug and alcohol addiction treatment options available in your area.
