For example, instead of swallowing your tablets, you might crush and then snort or inject them. Using the medicine for another purpose, such as getting high.
• Misusing over-the-counter medicines, including using them for another purpose or in a different way than you are supposed to.

Drug use is dangerous. It can harm your brain and body, sometimes permanently. It can hurt the people around you, including friends, families, and kids. If you are pregnant, it can harm your fetus. Drug use can also lead to mild, moderate, or severe substance use disorders. Substance use disorders are sometimes called addiction.

What is drug addiction?

From: MedlinePlus, National Library of Medicine

Drug addiction is a chronic brain disease. It causes a person to take drugs repeatedly, despite the harm they cause. Repeated drug use can change the brain and lead to addiction.

The brain changes from addiction can be lasting, so drug addiction is considered a "relapsing" disease. This means that people in recovery are at risk for taking drugs again, even after years of not taking them.

Does everyone who takes drugs become addicted?

From: MedlinePlus, National Library of Medicine

Not everyone who uses drugs becomes addicted. Everyone's bodies and brains are different, so their reactions to drugs can also be different. Some people may become addicted quickly, or it may happen over time. Other people never become addicted. Whether or not someone becomes addicted depends on many factors. They include genetic, environmental, and developmental factors.

Who is at risk for drug addiction?

From: MedlinePlus, National Library of Medicine

Various risk factors can make you more likely to become addicted to drugs, including:

• Your biology. People can react to drugs differently. Some people like the feeling the first time they try a drug and want more. Others hate how it feels and never try it again.
• Mental health problems. People who have untreated mental health problems, such as depression, anxiety, or attention deficit/hyperactivity disorder (ADHD) are more likely to become addicted. This can happen because drug use and mental health problems affect the same parts of the brain. Also, people with these problems may use drugs to try to feel better.
• Trouble at home. If your home is an unhappy place or was when you were growing up, you might be more likely to have a drug problem.
• Trouble in school, at work, or with making friends. You might use drugs to get your mind off these problems.
• Hanging around other people who use drugs. They might encourage you to try drugs.
• Starting drug use when you're young. When kids use drugs, it affects how their bodies and brains finish growing. This increases your chances of becoming addicted when you're an adult.

What are the signs that someone has a drug problem?

From: MedlinePlus, National Library of Medicine

• Changing friends a lot
• Spending a lot of time alone
• Losing interest in favorite things
• Not taking care of themselves - for example, not taking showers, changing clothes, or brushing their teeth
• Being very energetic, talking fast, or saying things that don't make sense
• Quickly changing between feeling bad and feeling good
• Having different eating or sleeping habits
• Missing important appointments
• Having problems at work or at school
• Having problems in personal or family relationships

What are the treatments for drug addiction?

From: MedlinePlus, National Library of Medicine

Treatments for drug addiction include counseling, medicines, or both. Research shows that combining medicines with counseling gives most people the best chance of success.

The counseling may be individual, family, and/or group therapy. It can help you:

• Understand why the drug addiction began
• See how drugs changed your behavior
• Learn how to manage personal problems
• Learn to avoid places, people, and situations where drugs are accessible

If you stop or cut back on drugs you've used for a while, you may display different symptoms for different drugs. This is called withdrawal. Medicines can help with the symptoms of withdrawal. For addiction to certain drugs, there are also medicines that can help you re-establish normal brain function and decrease your cravings.

If you have a mental disorder along with an addiction, it is known as a dual diagnosis. It is important to treat both problems. This will increase your chance of success.

If you have a severe addiction, you may need hospital-based or residential treatment. Residential treatment programs combine housing and treatment services.

Can drug use and addiction be prevented?

From: MedlinePlus, National Library of Medicine

Drug use and addiction are preventable. Prevention programs involving families, schools, communities, and the media may prevent or reduce drug use and addiction. These programs include education and outreach to help people understand the risks of drug use.

Which doctor should you see?

The suggested department for discussing Drug Use and Addiction is Psychiatry, with a psychiatrist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• How are symptoms affecting safety, sleep, relationships and everyday function?
• What roles could psychological treatment, medicines or support services have?
• Who should be contacted if safety or functioning deteriorates?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
