One of the defining features of drug and alcohol addiction is that it often starts as an attempt to manage pain, stress, or emotional discomfort. When someone loses a job, experiences a breakup, lives with chronic pain, or faces unresolved trauma, the emotions that follow can feel overwhelming. Using substances to “take the edge off” can quickly become a pattern of self-medication.

Drugs and alcohol are chemicals that act on the brain’s reward system, releasing large amounts of dopamine and other neurotransmitters that create pleasurable sensations or a euphoric high.(Source) When a person repeatedly turns to substances to cope with stress or difficult feelings, the brain begins to adapt. Over time, the person may feel unable to function or feel “normal” without using, and addiction develops.(Source)

Even after someone recognizes their addiction—whether through a personal wake-up call, a medical crisis, or an intervention by loved ones—and completes a rehab program, the underlying condition does not simply disappear. Addiction is now widely recognized as a chronic brain disease, similar in many ways to other chronic illnesses that require ongoing management.(Source)

Relapse is common in addiction recovery and does not mean treatment has failed. Large studies have found that relapse rates for substance use disorders are similar to those for other chronic conditions such as diabetes, hypertension, and asthma.(Source) What matters most is how quickly someone responds to a slip or relapse, and whether they use it as a signal to adjust their recovery plan.

The cycle of addiction is often described in three main stages:(Source)

1. Binge/Intoxication – A strong urge or compulsion to seek and use the substance, followed by intoxication.
2. Withdrawal – When the substance wears off, the person may experience physical and emotional withdrawal symptoms, such as anxiety, irritability, low mood, or physical discomfort.
3. Craving/Relapse – The brain becomes preoccupied with obtaining and using the substance again, leading to cravings and a high risk of relapse.

This cycle can feel impossible to break, but it is not permanent. With the right treatment, support, and coping skills, people can interrupt this pattern, reduce cravings, and build a stable, substance-free life.
