If an individual with drug dependence stops taking that drug suddenly, that person will experience predictable and measurable symptoms, known as a withdrawal syndrome.

Dependence is caused by changes in the body as a result of constant exposure to a drug. Drug dependence is a medically treatable condition. The goal is to separate the patient from the drug slowly, instead of suddenly, to allow the body to readjust to normal functioning.

For patients who have developed dependence as a side effect of taking a Drug dependence medication e. They may also substitute dangerous drugs with similar—but safer—drugs to manage dependence.

For example, people detoxing from heroin are often given a longer-acting opioid like methadone or buprenorphine to alleviate withdrawal symptoms and cravings. Detox is a relatively short-term process lasting several days to several weeks that helps drug abusers safely stop taking drugs while avoiding dangerous withdrawal symptoms.

While the detox process is a necessary step towards recovery, detox does little itself to treat addiction in the long term. Research has shown that individuals who do not participate in drug treatment programs after undergoing detox are likely to relapse and end up needing detox again in the future 5.

Just as some drugs that cause dependence are not addictive, there are also highly addictive drugs that do not produce physical withdrawal symptoms. Even after long periods of abuse, psychostimulant drugs, including cocaine and methamphetaminedo not produce pronounced physical withdrawal symptoms like vomiting and shaking, although there can be psychological symptoms such as depression, anxiety, and drug cravings 6.

Individuals can develop addictions to illicit street drugs, prescription medications, and even activities such as gambling. Addictions are persistent, and addicted individuals can relapse into drug use after years of abstaining. Although addiction used to be thought of as a sign of moral weakness, it is now understood by the majority of those in the substance abuse and addiction treatment sphere to be a condition that arises in association with changes in the brain caused by the use of addictive substances.

This is because nearly all addictive drugs either directly or indirectly activate an area of the brain, the nucleus accumbens, that is normally stimulated by naturally rewarding activities important for survival like eating, having sex, or spending time with friends.

To the addicted brain, obtaining and taking drugs can literally feel like a matter of life and death. Addictive drugs stimulate pleasure and motivation pathways in the brain much more strongly than natural rewards. Therefore, repeated exposure to these drugs can fool the brain into prioritizing drug-taking over normal, healthy activities.

The inability to limit or cease substance use. The irresistible urge to continue seeking and taking the drug despite serious negative consequences.
