This three-pound mass of gray and white matter sits at the center of all human activity—you need it to drive a car, to enjoy a meal, to breathe, to create an artistic masterpiece, and to enjoy everyday activities. The brain regulates your body’s basic functions, enables you to interpret and respond to everything you experience, and shapes your behavior. In short, your brain is you—everything you think and feel, and who you are.
How Opioids Affect Your Brain in the Long and Short Term
Initially, they can provide pain relief and feelings of euphoria that are pleasurable and rewarding. But if you take opioids for too long, your brain will eventually start encouraging you to take more. This is why a person who misuses drugs eventually feels flat, without motivation, lifeless, and/or depressed, and is unable to enjoy things that were previously pleasurable. Now, the person needs to keep taking drugs to experience even a normal level of reward—which only makes the problem worse, like a vicious cycle.
Stage 2 Tolerance
But therapy and community help increase the chances you stick with it. A drug like heroin creates a tidal wave in the reward circuits of the brain. But on the inside you feel like a master of the universe, like you’re being “hugged by Jesus,” as one user said; there’s peace in your skin and not a single demi moore sober feeling of pain.

When opioid receptors adapt to heroin and become less responsive, other changes occur that make the brain rely on the drug to function how to help someone with a drinking problem normally. Without heroin, the opioid receptors of a dependent person act abnormally. As research progresses, we may discover new approaches to mitigating the harmful effects of heroin on the brain. For instance, understanding the interactions between different drugs and neurotransmitter systems, such as Suboxone and dopamine, can lead to more effective medication-assisted treatments for opioid addiction. The initial effects of heroin occur when the drug attaches to opioid receptors in the brain. It takes less than 20 minutes for the body to convert heroin to morphine and 6-MAM.
That’s why many people say using heroin feels like extreme happiness or relaxation. Heroin has been around since the 1870s, and its addictive properties came to light very quickly. It works by converting to morphine in the body and binding to your opioid receptors, which causes pleasurable feelings, a sensation of heaviness but also itching, nausea and sometimes vomiting. One of the most significant long-term effects is the alteration of the brain’s reward system. Repeated exposure to heroin can lead to a decrease in the brain’s natural ability to produce dopamine and respond to natural rewards. This change can result in anhedonia, a condition where individuals struggle to experience pleasure from activities they once enjoyed.
Some people are what is drinker’s nose able to fully recover because they weren’t without oxygen for enough time for brain cells to die. With significant physiological dependence, an individual may continue to compulsively use heroin to avoid unwanted and unpleasant withdrawal symptoms. You naturally produce endorphins, the body’s own version of opioids, which act in the reward circuits of the brain to make you feel good after you work out, hug a friend or eat your favorite foods. Some turn to heroin because prescription painkillers are tough to get. Fentanyl, which is 50 times more potent than heroin, has snaked its way into other drugs like cocaine, Xanax and MDMA, widening the epidemic. Chronic drug use leads to ‘hypofrontality’, which causes the prefrontal cortex to become less effective.
Challenges of overcoming heroin addiction
Treatment centers that promote abstinence are at odds with the medical standard of care — long-term use of medications, like buprenorphine, methadone and naltrexone. Scoring the next fix feels like a race against the clock of withdrawal. It makes no sense, but this compulsion takes over all logic, judgment and self-interest. Overdoses have passed car crashes and gun violence to become the leading cause of death for Americans under 55.

- This comparative approach can provide valuable insights into the nature of addiction and inform more effective treatment strategies across different substance use disorders.
- The immediate effects of heroin on the brain are profound and multifaceted.
Symptoms of withdrawal include restlessness, muscle and bone pain, insomnia, diarrhea, vomiting, cold flashes with goose bumps (“cold turkey”), and leg movements. Major withdrawal symptoms peak between 24–48 hours after the last dose of heroin and subside after about a week. However, some people have shown persistent withdrawal signs for many months. Once a person has heroin use disorder, seeking and using the drug becomes their primary purpose in life.
Morphine and 6-MAM stay in the brain for longer periods of time. These drugs continue to attach to opioid receptors for several hours. They likely cause prolonged effects that are milder than the initial high caused by heroin, according to a 2013 study published in the British Journal of Pharmacology.
