Heroin Rehab in NJ: Signs, Effects, and Addiction Treatment Options

Heroin addiction can be a devastating and dangerous substance use disorder to face. In New Jersey, the opioid crisis has kept heroin and fentanyl-laced heroin at the center of the overdose epidemic for many years, claiming thousands of lives and leaving families searching for answers.

If you or someone you care about is struggling with heroin addiction, you should know that recovery is possible and that professional treatment significantly increases the odds of it. At Meridian Recovery, we provide effective and empathetic heroin addiction treatment carefully designed to meet your needs.

  • Heroin is a highly addictive illicit opioid derived from morphine, often mixed with fentanyl, which greatly increases the risk of overdose.
  • It rapidly floods the brain with dopamine, creating intense euphoria and quickly leading to tolerance, dependence, and compulsive use.
  • Signs of heroin use include drowsiness, pinpoint pupils, track marks, weight loss, mood changes, and continued use despite serious consequences.
  • Long-term use can cause severe health issues such as brain damage, heart infections, respiratory problems, and increased risk of infectious diseases.
  • Effective treatment typically includes medication-assisted treatment (like buprenorphine or methadone) combined with behavioral therapy and support for co-occurring mental health conditions.

What Is Heroin?


Heroin is an illicit drug derived from morphine, which is naturally produced from the seed pods of the opium poppy plant. It is classified as a Schedule I controlled substance, meaning that it has no accepted medical use and a high potential for abuse.[1]

Heroin sold in New Jersey and throughout the country is frequently mixed with illicitly manufactured fentanyl, an opioid many times more potent than heroin itself.[2]  For this reason, it has become increasingly difficult for heroin users to know the true potency of what they are using, greatly increasing the incidence of overdose. According to the CDC, synthetic opioids, including fentanyl, are involved in the overwhelming majority of overdose deaths caused by heroin in the United States.[3]

 

What Does Heroin Look Like?

Heroin can be found as a white or brown powder, or as a sticky black tar substance (commonly referred to as black tar heroin), and can be injected, snorted, or smoked, with injection providing the quickest and most intense euphoric effect.

 

Why Is Heroin So Addictive?


Heroin quickly and powerfully binds to both the brain and body’s opioid receptors when it is used, creating a flood of dopamine to the brain’s pleasure and reward areas.[4] This produces an intense rush of euphoria, and it’s this powerful reward signal that is the root cause of heroin’s addictive potential. The brain immediately registers the pleasurable experience and begins creating associations that drive the compulsive drug-seeking behavior that those addicted to heroin are known for.[5]

With repeated use, the body begins to decrease its production of naturally occurring dopamine, ultimately developing dependence on heroin to achieve a baseline level of function. Rapid tolerance develops, requiring progressively larger and more frequent doses in order to prevent withdrawal. The cycle of using heroin to avoid withdrawal as opposed to using it for pleasure usually follows and is one of the most difficult challenges to overcome, and often the reason people are unable to stop using without professional intervention.[6]

 

Signs of Heroin Use


There are a number of signs of heroin use that vary from subtle during early stages to unmistakable once an addiction has developed. People who are using heroin may display many of the following warning signs:

  • Extreme drowsiness or falling asleep while talking
  • Constricted (pinpoint) pupils, regardless of the lighting
  • Slurred speech or impaired coordination
  • Evidence of injecting drugs: track marks, bruising, collapsed veins from repeated use
  • Burnt spoons, syringes, or small folded papers found in personal space
  • Noticeably dramatic decline in weight or changes in appearance
  • Wearing long-sleeved clothing during warm weather to cover evidence of injections
  • Isolating themselves from family, friends, and responsibilities
  • Significant changes in mood; cycling between calm and frantic
  • Unexplained financial difficulties or disappearing valuables
  • Continued use despite knowing the risk of overdose

Heroin addiction is a serious condition, but one that can be treated and one that people overcome every day.

Effects and Long-Term Consequences of Heroin Use

Heroin use has short-term effects such as an initial euphoric rush, sedation, dry mouth, and slowed breathing. However, if someone takes a higher dose or takes heroin laced with fentanyl, they could also experience respiratory depression, which could be fatal.

The following are some of the long-term effects of heroin use:[7]

  • Neurological System: Deterioration of the brain’s white matter, affecting decision making, behavior regulation, and stress response.
  • Cardiovascular System: Increased risk of heart lining infection, known as endocarditis, especially for intravenous users.
  • Infectious Disease: Use of shared equipment and needles increases the risk for HIV, Hepatitis B, and Hepatitis C.
  • Respiratory System: Chronic pneumonia and other pulmonary complications.
  • Liver and Kidney: Organs progressively become damaged over time due to long-term heroin use.
  • Mental Health: Worsening of depression and anxiety, as well as trauma-related disorders for some, due to the consequences of addiction.

 

What To Expect From Heroin Addiction Treatment


The health complications associated with long-term use of heroin make it critically important for early intervention and access to comprehensive heroin rehabilitation. 

Medication-Assisted Treatment (MAT)

There is a wealth of research backing the effectiveness of MAT for treating opioid dependence. It has been endorsed by SAMSHA, NIDA, and the medical community as the gold standard for treating heroin addiction.[8] 

Three examples of FDA-approved medications used in the treatment of heroin use disorder include:

  • Buprenorphine (Suboxone): Reduces cravings and withdrawal symptoms, stabilizes brain chemistry, and dramatically reduces overdose risk. One of the most commonly used and effective medications in heroin addiction treatment.
  • Methadone: A long-acting opioid agonist, particularly effective for those with severe or long-standing heroin dependence.
  • Naltrexone (Vivitrol): Blocks the euphoric effects of heroin entirely. Best suited for people who have completed detox and are fully opioid-free before beginning treatment.

Alongside MAT, behavioral therapy addresses the psychological patterns, trauma, and underlying mental health conditions that sustain heroin use. 

Heroin and Co-Occurring Disorder Treatment

At Meridian Recovery, our heroin rehabilitation program helps people suffering from heroin addiction as well as any co-occurring mental health disorders they may have. Many people with heroin use disorder also struggle with depression, anxiety, post-traumatic stress disorder (PTSD), and other co-occurring mental disorders. Effective treatment requires addressing both the physical dependence and the psychological, emotional, and social aspects of addiction.

 

Untreated mental disorders or co-occurring disorders are among the root causes for heroin usage and eventual addiction, as many start their use as a way to self-manage these conditions.[9] 

Our dual diagnosis approach provides integrated treatment for both the heroin addiction itself and the underlying mental health conditions that may have contributed to it.

Why is heroin so addictive?

Heroin creates an addictive cycle because it quickly binds to the opioid receptors in the brain, creating a rapid increase in dopamine, which is then encoded by the reward system as a priority. After using heroin repeatedly, the brain decreases its natural production of dopamine, leading to a state of dependence and causing stopping the use of the drug to feel almost impossible without assistance. Both the speed in which the addiction creates itself and the severity of withdrawal make heroin one of the most difficult substances to stop using without professional help.

What does heroin withdrawal feel like?

Heroin withdrawal is extremely uncomfortable and begins approximately 6-12 hours after the last use, reaching maximum intensity approximately 48-72 hours after the last use and generally improving after about 7 days for most people. Symptoms include severe muscle pain, heavy sweating, chills, vomiting, nausea, diarrhea, insomnia, anxiety, and uncontrollable desire for heroin.

What kind of heroin treatment options are available in New Jersey?

The state of New Jersey has a variety of treatment options available for patients with heroin use disorder, including medically supervised detox, partial hospitalization programs (PHP), intensive outpatient programs (IOP), standard outpatient treatment, and aftercare programs. At Meridian Recovery, we offer PHP, IOP, and outpatient care for patients recovering from heroin addiction.

How does medication-assisted treatment help with heroin addiction?

MAT reduces craving and withdrawal symptoms, maintains a stable chemistry in the brain, and greatly reduces the risk of overdose and relapse. Additionally, the research has shown that people being treated using MAT will have better treatment outcomes compared to people who are treated via only abstinence, including a decrease in rates of overdose deaths, better treatment retention, and an increase in quality of life.
