What Are The Physical Effects Of Heroin Addiction

How do drugs affect the brain? – Sara Garofalo

While the psychological effects of heroin addiction are not to be minimized, the physical effects of heroin are as wide-ranging as they are damaging, working to destroy the body from all sides. It starts with a general decline in personal hygiene and addressing basic needs like eating properly and getting enough sleep, in other words, things that used to release dopamine but now pale in comparison to what heroin can provide.

Some physical effects of heroin addiction on the body include:

Why Heroin Causes Pleasure & Pain Relief

When the body feels pleasure, such as when you hug a loved one, a small amount of endorphins attach to the brains opioid receptors. But heroin overwhelms the receptors, causing a large surge in happiness. Thats why many people say using heroin feels like extreme happiness or relaxation.

Opioid receptors affect more than happiness. Heroin can temporarily relieve feelings of depression or anxiety. The drug can also relieve pain the same way that prescription opioids relieve pain. High doses of opioids attach to opioid receptors, which prevents the brain from making you feel any type of pain.

The immediate positives associated with heroin arent worth the risks. Opioid receptors control important life functions, and heroin disrupts these processes. When the brain is flooded with heroin, opioid receptors in the brain can no longer tell the body how to function properly.

How Heroin Creates Addiction

Each time people use heroin, it reinforces changes in the brains reward system that cause cravings. Brain receptors continue to adapt to heroin exposure, making people more dependent on the drug as they continue to use it.

Depending on a variety of genetic and environmental factors, some people develop a disease called heroin addiction because of changes to areas of the brain that affect self-control, motivation and pleasure. Most of the time, these people seek heroin for the sole purpose of avoiding withdrawal.

Without heroin treatmetn, people addicted to the drug may be unable to quit. They are often incapable of reversing the long-term changes that heroin has caused without professional help.

Detoxing from heroin helps the brain recover from adaptations that cause dependence. Once people complete detox and overcome withdrawal, counseling and therapy can help them learn how to control cravings and make healthy decisions.

What Happens To Your Brain When You Use Methamphetamine

All drugs change the way the brain works by changing the way nerve cells communicate. Nerve cells, called neurons, send messages to each other by releasing chemicals called neurotransmitters, telling us how to act and behave. These neurotransmitters attach to molecules on neurons called receptors.

There are many neurotransmitters, but dopamine is the one that reinforces cravings for pleasurable behaviors,  like eating a piece of chocolate cake or playing a video game. With repeated use, stimulants like methamphetamine can disrupt how the brains dopamine system works, reducing a persons ability to feel pleasure from normal, everyday activities. People will often develop tolerance, which means they must take more of the drug to get the desired effect. If a person becomes addicted, they might take the drug just to feel normal.

After the “high” of methamphetamine wears off, many people experience a “crash” and feel tired or sad for days. They also experience a strong craving to take methamphetamine again to try to feel better.

Pharmacological Interventions And Treatment Implications

How Does Heroin Withdrawal Affect the Brain?

In summary, the various biological models of drug addiction are complementary and broadly applicable to chemical addictions. Long-term pharmacotherapies for opioid dependence and addiction counteract or reverse the abnormalities underlying those conditions, thereby enhancing programs of psychological rehabilitation. Short-term treatments for relieving withdrawal symptoms and increasing abstinence are beyond the scope of this article; instead, we refer readers elsewhere for detailed neurobiological explanations of the various nonopioid-based abstinence initiation approaches such as clonidine and clonidine-naltrex-one for rapid detoxification .

The medications most commonly used to treat opioid abuse attach to the brain cells mu opioid receptors, like the addictive opioids themselves. Methadone and LAAM stimulate the cells much as the illicit opioids do, but they have different effects because of their different durations of action. Naltrexone and buprenorphine stimulate the cells in ways quite distinct from the addictive opioids. Each medication can play a role in comprehensive treatment for opioid addiction.

How Heroin Causes Tolerance

After repeated heroin use, opioid receptors in the brain adapt by becoming less responsive. This is called tolerance. People with a high tolerance to heroin feel less pleasure when using the drug because their opioid receptors have become less sensitive to its effects. Some people with a high tolerance end up taking higher doses of heroin to feel pleasure. As the person continues to use heroin, opioid receptors continuously adapt to the increasing doses. Thus, the persons tolerance continues to increase.

Why Are More People Using Heroin

The number of people in the United States who use heroin has risen steadily since 2007.

One thing that plays a role in the rise is the growing abuse of prescription painkillers such as oxycodone and hydrocodone, which are also made from the poppy plant and are chemically related to heroin. People who misuse these drugs may start looking for a stronger, cheaper high. Heroin is both. But it’s also more dangerous. Thereâs no way to know what youâre taking or how strong it is.

The U.S. heroin overdose death rate rose nearly 400% between 2010 and 2017. Some of these deaths happen because heroin is laced with other drugs, such as the powerful painkiller fentanyl.

The Effects Of Drugs On The Human Brain

Our brains consist of different centers that control various bodily functions, enable thinking and reasoning, elicit emotional responses, and more. Three of the primary centers of the brain that drugs can effect include

1. Limbic System:

The limbic system is often referred to as the brains reward center. It is responsible for making us feel pleasure when we eat, socialize, or have sex. It also affects our emotional responses to help us distinguish between positive emotions, like joy, and negative ones, like sadness.

Our brain remembers what types of activities bring us pleasure and make us feel happy. In a way, it encourages us to repeat these types of behaviors and avoid those that create negative responses.

2. Cerebral Cortex:

The cerebral cortex helps us process and interpret information from different sources using the senses of sight, smell, taste, sound, and touch. For instance, you accidentally touch a hot burner, and the cerebral cortex interprets this action as painful since we burned our hand. Conversely, touching something soft and warm can be interpreted as inviting and good.

The frontal cortex, situated at the front of the cerebral cortex, is where all of our thinking and thought processes occur. This part of the brain helps us reason, make decisions, solve problems, determine risks and rewards of our behaviors and actions, and communicate with others.

What Happens To Your Brain When You Use Heroin

How heroin affects the mind and body — The Doctors

When heroin enters the brain, it attaches to molecules on cells known as opioid receptors. These receptors are located in many areas of the brain and body, especially areas involved in the perception of pain and pleasure, as well as a part of the brain that regulates breathing.

Short-term effects of heroin include a rush of good feelings and clouded thinking. These effects can last for a few hours, and during this time people feel drowsy, and their heart rate and breathing slow down. When the drug wears off, people experience a depressed mood and often crave the drug to regain the good feelings.

Regular heroin use changes the functioning of the brain. Using heroin repeatedly can result in:

  • tolerance: more of the drug is needed to achieve the same high
  • dependence: the need to continue use of the drug to avoid withdrawal symptoms
  • addiction: a devastating brain disease where, without proper treatment, people have trouble stopping using drugs even when they really want to and even after it causes terrible consequences to their health and other parts of their lives. Because of changes to how the brain functions after repeated drug use, people that are addicted crave the drug just to feel normal.

What Part Of The Brain Is Responsible For Heroin Addiction

The feeling of pleasure plays an important role in a healthy brain, as it helps us identify and reinforce healthy behaviors. We are hard-wired to repeat pleasurable behaviors and experiences which trigger our reward circuit in the brain and cause a burst of the neurotransmitter dopamine. This is how healthy, desirable habits and routines are formed.1

But the problem is that the mechanism is the same when it comes to unhealthy, detrimental habits such as drug-seeking behavior and drug use. Namely, drugs such as heroin produce intense euphoria and an intense surge of dopamine.1

In doing so, they reinforce the connection between drug use and the pleasure derived from it. This learned reflex can cause lasting changes in the reward circuit. The brain also remembers any external cues associated with the experience, which can trigger uncontrollable cravings even in people who have been off heroin for a decade.1

Effects Of Prescription Opioids And Heroin On The Brain

Opioids work as central nervous system depressants to slow down the brains activity. When taken, opioids attach themselves to the receptors in the brain and mimic the behaviors of a natural neurotransmitter. While this makes opioids effective at blocking pain and creating a calming effect throughout the body, they can also dangerously slow down breathing and heart rate.

Opioid painkillers and heroin are among the most addictive drugs. Dependence on these drugs can form quickly because of their ability to create what users describe as a euphoric high almost instantaneously. While this may be true, the pleasurable high is only part of the reason that opioids are so addictive.

Prescription opioids and heroin are also addictive because they activate the reward center in the brain. In order to activate the reward center, opioids flood your system with the feel-good chemical dopamine. Your mind is wired to remember and seek out the activities that stimulated your reward center and teaches you to do these things again and again to get the same euphoric rush. Due to this, your brain can form a dependence to opioids quite rapidly.

Can A Person Overdose On Heroin

17+ best images about Science of Addiction on Pinterest ...

Yes, a person can overdose on heroin. A heroin overdose occurs when a person uses enough of the drug to produce a life-threatening reaction or death. Heroin overdoses have increased in recent years.

When people overdose on heroin, their breathing often slows or stops. This can decrease the amount of oxygen that reaches the brain, a condition called hypoxia. Hypoxia can have short- and long-term mental effects and effects on the nervous system, including coma and permanent brain damage.

How Does The Brain Work

The brain is often likened to an incredibly complex and intricate computer. Instead of electrical circuits on the silicon chips that control our electronic devices, the brain consists of billions of cells, called neurons, which are organized into circuits and networks. Each neuron acts as a switch controlling the flow of information. If a neuron receives enough signals from other neurons that it is connected to, it fires, sending its own signal on to other neurons in the circuit.

The brain is made up of many parts with interconnected circuits that all work together as a team. Different brain circuits are responsible for coordinating and performing specific functions. Networks of neurons send signals back and forth to each other and among different parts of the brain, the spinal cord, and nerves in the rest of the body .

To send a message, a neuron releases a neurotransmitter into the gap  between it and the next cell. The neurotransmitter crosses the synapse and attaches to receptors on the receiving neuron, like a key into a lock. This causes changes in the receiving cell. Other molecules called transporters recycle neurotransmitters , thereby limiting or shutting off the signal between neurons.

Withdrawal From Heroin Abuse

Another impact of heroin on the body is withdrawal. When a physical dependence on heroin exists and the drug is stopped, a person will begin to experience withdrawal. Heroin withdrawal symptoms last anywhere from a few days to more than a week. Typically, they start within six to 12 hours of the last dose, peak in two to three days, and last up to 10 days in total.

Withdrawal may include the following symptoms:

  • cold flashes with goosebumps

What Does Heroin Do To Your Body And Brain

What does Heroin do to your brain and body? | Earth Lab

Any kind of drug or chemical that is put into the body is going to have effects on how the body naturally functions. Drugs such as heroin can cause significant damage to the brain and other vital organs. Some of these damaging effects can be seen almost immediately while others take time to manifest their symptoms. Not only does heroin directly cause significant effects to the body itself, but it is also accompanied by the dangers of the lifestyle that goes along with heroin use, such as sharing needles and doses that are mixed with other street drugs. Although the accumulated potential damage that users contribute to each time that they use is significant, the largest danger from this drug is that each dose could be fatal.

The Issue Of Addiction

Stimulation is, in part, why people become dependent on drugs. Consistent drug use leads to tolerance, enjoyment, and mind-altering effects. The more someone changes normal brain function, the more likely dependence will occur.

Say youve taken opioids over an extended period. Your brain has released excessive amounts of dopamine, the pleasure neuron, the entire time. If you abruptly stop taking the opioids, your brain will crave that same unnatural level of dopamine release, reinforcing the need to use.

Drugs affect all parts of the brain  the prefrontal cortex, the amygdala , the limbic system, and more. They drastically affect our neurotransmitters, causing irregular messages to be sent throughout our nervous system. This affects how we walk, talk, and remember things, as well as our ability to develop and learn.

Once the brain adapts to consistent drug use, it becomes reliant on it, triggering dangerous and risky behaviors all to support the intention of getting more of the drug, at any cost. This is why people who were once clean, kind, and compassionate are driven to steal money from family members or engage in other illegal activities. The addiction has taken over at this point; the individual has less and less control over their actions. They are fighting their own brains, trying to stop overwhelming urges. This is why its essential to treat addiction as a disease, not a choice.

What Effects Does Heroin Have On The Body

Heroin binds to and activates specific receptors in the brain called mu-opioid receptors . Our bodies contain naturally occurring chemicals called neurotransmitters that bind to these receptors throughout the brain and body to regulate pain, hormone release, and feelings of well-being. When MORs are activated in the reward center of the brain, they stimulate the release of the neurotransmitter dopamine, causing a reinforcement of drug taking behavior. The consequences of activating opioid receptors with externally administered opioids such as heroin depend on a variety of factors: how much is used, where in the brain or body it binds, how strongly it binds and for how long, how quickly it gets there, and what happens afterward.

How Drugs Affect The Brain

Not only do drugs have a plethora of harmful effects, different drugs have very different effects. For example, the brains response to marijuana is much different than its response to cocaine or heroin.

There are many kinds of neurotransmitters in the brain, not just one. Youve likely heard of many of them dopamine, serotonin, and endorphins, for example. Each neurotransmitter is responsible for something different, whether that be our pleasure and reward system or our impulse control.

When someone uses drugs, these neurotransmitters are either enhanced or depleted. Certain drugs, like marijuana, mimic chemicals and actions that already occur within the brain. Although theyre similar, the signals are still different enough that they cause your brain to work harder to process any internal messages sent.

Other drugs, such as heroin or cocaine, have almost the opposite effect. They either under- or over-stimulate these neurotransmitters, causing either a huge release or an overwhelming lull. This disrupts any of the conversations we have going on between our brain and the nervous system.

Cause Of Opiate Addiction

How heroin affects the body

The likelihood that a drug will lead to addiction is linked to the speed with which that drug promotes dopamine, the intensity of dopamine effects and the reliability that dopamine effects will occur.

Opiates like heroin, morphine and oxycodone are fast acting, produce a lot of dopamine and work close to 100% of the time. Thats why these three opiates in particular have been linked to several opiate addiction epidemics. The U.S. is currently coming out of an oxycodone epidemic and were currently in another heroin epidemic. The only morphine epidemic began during the Civil War and was quickly supplanted by heroin at the beginning of the 20th century.

How Does Heroin Cause Tolerance

Normally, people have the ability to derive pleasure from naturally rewarding activities. With prolonged, repeated use of heroin, the person loses this ability. This is because, unlike natural rewards, drug rewards have an abnormal effect on the brain. The person enters a vicious circle in which they can no longer enjoy other activities that they used to find pleasurable and can only derive pleasure from seeking and using heroin.1 

Because of heroins potent effect on the reward system in the brain, the person needs to maintain a consistent level of exposure to heroin to experience a normal level of reward. Repetitive use of heroin leads to increased tolerance to the drug and the person needs increasingly high doses to experience the familiar high. The next step is physical dependence.1

How Long Does Heroin Work

6MAM has a short elimination half-life, which ranges between 6-25 minutes. Therefore, approximately 30 minutes after heroin is administered, over half of 6MAM molecules will have metabolized into heroins second metabolite, that is to say morphine. Morphines half-life is around 2.5 5 hours. Heroins half-life is considered the total of these two, and that means heroins half-life is a little less than 3 5.5 hours. The drug-effects of heroin last between one and two half-lives or 3 11 hours. The mean average being 7 hours.

Morphine activates opioid receptors longer than all other active metabolites of heroin. Therefore, the lingering drug effects are more connected to morphine, while the acute drug effects are more connected to 6MAM, but they do overlap.

Psychological And Physical Effects Of Long

There is no denying that heroin is an incredibly dangerous drug. In the midst of the opioid crisis, heroin abuse has resulted in tens of thousands of overdose deaths, accounting for nearly 16,000 deaths in the United States in 2016.

The high chances of a fatal overdose are certainly frightening enough, especially when considering how often heroin is cut with the deadly synthetic opioid analog fentanyl. However, even if someone avoids overdosing, the long-term effects of heroin can cause serious, potentially fatal issues both physically and psychologically.

Heroin addiction has the power to take a healthy person and leave them crippled with severe health problems, vulnerable to infectious diseases, and with potentially permanent damage to their brain functioning and major bodily organs.

Overdosing on heroin is a danger that should never be taken lightly, but it is also incredibly important that people understand the long-term effects of heroin abuse and how addiction can destroy your body and your brain without ever experiencing an overdose.

What Happens To Your Brain When You Misuse Anabolic Steroids

Anabolic steroids affect a part of the brain called the limbic system, which controls mood. They dont cause a high like some other drugs, but can cause harmful effects.

Long-term steroid misuse can lead to aggressive behavior and extreme mood swings. This is sometimes referred to as roid rage. It can also lead to feeling paranoid , jealous, delusional , and invincible .

Heroin Dependence And Tolerance

As with some other drugs, a person can build up a tolerance to heroin. After only a short time, the person using heroin will need to take larger doses to achieve the same effect. Soon their body will start to depend on heroin in order to function normally.For some people who are dependent on heroin, nothing else in life matters except the drug. They may ignore their career, relationships and even basic needs like eating. Financial, legal and other personal problems may be related to heroin use. The person craves the drug and this psychological dependence makes them panic if they cannot have it, even temporarily.

Why Is This Happening

Firstly, and most importantly: you havent failed. There are many paths that lead people to drugs. But when your loved one misuses substances, it impacts the family; and, if not stopped, will have long-term effects on their future.  Drug use is progressive. The internal rule books we use as adults – the shouldnts, wouldnts, wonts – no longer apply. And once someone has gotten hooked on a substance, theyll move on to something stronger. Falling in with the wrong crowd, societal pressures, anxiety and mental health issues can all have a profound impact. This is how addiction spirals.

We might know that the person in question has a few casual glasses of wine with dinner but be shocked to learn about the Xanax they took beforehand. We might suspect they smoke cannabis but have no clue theyre actually buying or dealing. Perhaps we joke with them about staying up late but are unaware that theyve barely been sleeping – because its easier to engage in these kinds of behaviours while everyone else is asleep.
