Addiction

Addiction affects the brain's reward, motivation and self-control systems. Over time, a substance or behavior that once brought pleasure or relief becomes something a person feels compelled to repeat, even as it damages health, relationships, work or finances.

Substance use disorder can involve alcohol, opioids, cannabis, stimulants, sedatives, nicotine and other drugs. It ranges from mild to severe depending on how many signs are present. Behavioral addictions, such as gambling addiction, follow similar patterns of craving, loss of control and continued use despite harm.

Drug addiction and other forms of addiction are not a sign of weak willpower or bad character. Genetics, mental health, life circumstances and the substance itself all play a role. Stigma often stops people from seeking help, yet addiction responds to treatment much like other long-term health conditions. Many people reduce harm, stop using and build fulfilling lives in recovery.

Signs of addiction can be physical, psychological and social. They may include:

• Using more, or for longer, than intended
• Wanting to cut down but being unable to
• Spending a lot of time obtaining, using or recovering from a substance
• Strong cravings or urges
• Neglecting responsibilities at work, school or home
• Continuing despite relationship problems or health issues
• Giving up activities that used to matter
• Using in risky situations, such as while driving
• Needing more to get the same effect (tolerance)
• Withdrawal symptoms when stopping, such as shakiness, sweating, anxiety or nausea
• Secrecy, mood swings or changes in friends and routines

Not everyone shows every sign. If you recognize several of these in yourself or someone close to you, it is worth speaking to a doctor or addiction specialist. Some withdrawal symptoms, particularly from alcohol or sedatives, can be dangerous, so stopping suddenly should be discussed with a medical professional.

Addiction usually develops from a combination of factors rather than a single cause:

• Genetics and family history of substance use
• Early exposure to alcohol or drugs, especially during adolescence
• Mental health conditions such as depression, anxiety, ADHD, PTSD or bipolar disorder
• Trauma, including childhood adversity
• Chronic stress, loneliness or social isolation
• Peer, family or community environments where substance use is common
• Easy access to substances
• The nature of the substance, as some are more addictive than others

Many people use substances to cope with emotional pain, stress or difficult memories. What begins as relief can turn into dependence. This is why treating co-occurring mental health problems is an important part of effective care.

Addiction treatment is tailored to the person, the substance and the severity of the problem. Options include:

• Medically supervised detox, when withdrawal could be uncomfortable or dangerous
• Outpatient therapy, where you attend sessions while living at home
• Intensive outpatient or day programs for more structure
• Residential treatment, often called rehab, which provides a supportive environment away from everyday triggers
• Medication-assisted treatment for some substance use disorders, prescribed and monitored by a doctor

Psychological therapies with good evidence include cognitive behavioral therapy (CBT), motivational interviewing, contingency management and family or couples therapy. Mindfulness-based relapse prevention and support for co-occurring conditions can also help. Mutual-support groups and peer recovery communities offer connection and encouragement for many people.

Harm reduction, which focuses on reducing the dangers of use for people who aren't ready to stop, is also a valid part of addiction care.

A psychologist, clinical psychologist or psychiatrist experienced in addiction can assess the problem and recommend treatment. Your primary care doctor is often a good first contact and can help with medical needs such as withdrawal.

At a first appointment, you'll be asked about what you use, how often, how it affects your life and whether you've tried to stop before. You may also be asked about mental health, physical health and your support network. Honesty helps the professional recommend the right level of care, and these conversations are confidential within legal limits.

Addiction recovery is often a process rather than a single event. Lapses can happen and are not a sign of failure. They are opportunities to learn and adjust the plan. Ongoing support after initial treatment greatly improves outcomes.

If someone is at risk of overdose, unresponsive or having trouble breathing, call 911 in the US or your local emergency number immediately. If substance use is linked to thoughts of suicide, call or text 988 in the US or call Samaritans on 116 123 in the UK and Ireland.

Watching someone you love struggle with addiction is painful. These steps can help:

• Choose a calm moment to talk, and use "I" statements about what you've noticed and how you feel
• Avoid labels, blame or lectures, which often lead to defensiveness
• Express care and offer concrete support, such as helping find a treatment provider
• Set clear boundaries to protect your wellbeing, and follow through on them
• Avoid covering up consequences, such as making excuses or paying debts
• Learn about addiction and recovery
• Seek support for yourself, such as therapy or family support groups

Many families find that the language of "addict" feels harsh; people-first terms like "a person with an addiction" can make conversations easier. You can't force someone to change, but you can encourage help and look after yourself along the way.
