What Are Co-Occurring Disorders

Key Takeaways

  • Fentanyl is a powerful opioid that becomes especially dangerous when made illegally or hidden in counterfeit pills and other drugs.
  • Fentanyl abuse can lead to dependence, withdrawal, addiction, and overdose, sometimes from a very small amount.
  • Treatment may include medical detox, residential care, therapy, mental health support, family education, and aftercare.

Like many other drugs, and certainly other opioids, there is still a lot of confusion about fentanyl, a powerful synthetic opioid that can be used safely in medical settings but can be deadly when made or sold illegally. For example, most people may not realize that fentanyl is not a recent development. It has actually existed since Dr. Paul Janssen developed it in 1959. The average person may also be surprised to learn that fentanyl is regularly used for pain relief in hospitals across the country.

But perhaps the biggest misconception around fentanyl may just be how deadly it is when taken illicitly, especially when it is mixed into counterfeit pills, heroin, cocaine, methamphetamine, or other street drugs without the person knowing. Today, fentanyl is one of the clearest examples of why opioid addiction, overdose prevention, and professional treatment matter so much..

At Midwest Recovery Centers, we help people struggling with fentanyl abuse and opioid addiction find safety, structure, and support. With the right treatment, long-term recovery is possible

“Fentanyl has dramatically changed the landscape of addiction because of its extreme potency and the growing presence of fentanyl in counterfeit pills and other illicit substances. Many people are exposed without realizing it, which significantly increases the risk of overdose, dependence, and death. Early intervention and professional treatment can be critical for improving safety and supporting long-term recovery.”

What is Fentanyl?

fentanyl is a synthetic opioid, which means it is created in a laboratory and meant to produce the same effect as natural opioids like morphine and codeine. Fentanyl is prescribed for severe pain because it attaches to opioid receptors in the brain and body, helping reduce pain signals while also causing relaxation or sedation. There are two very different forms of fentanyl, pharmaceutical fentanyl and illicitly manufactured fentanyl. 

Pharmaceutical fentanyl is prescribed by a doctor and used in medical settings with medical supervision to treat extreme pain, including pain after surgery or pain related to advanced-stage cancer. It may be given through IV medication, patches, tablets, nasal sprays, lozenges, or medication placed under the tongue

When people talk about the dangers of fentanyl, they’re referring to illicitly manufactured fentanyl. This form of the drug is sold and used illegally, most often in powder form or liquid form that may be turned into nasal sprays, eye drops, or added to blotter paper or edible candies. Some people may use illicit fentanyl to numb pain, while others use it for its euphoric effects. In many cases, though, people do not know they are taking fentanyl at all because it may be pressed into fake prescription pills or mixed into other substances.

According to the United States Drug Enforcement Administration (DEA), illicitly manufactured fentanyl is primarily manufactured abroad and smuggled into the U.S. for sale on the drug market. This illegal supply is especially dangerous because there is no medical oversight, no controlled dose, and no reliable way for a person to know exactly what they are taking.

“Fentanyl abuse can become life-threatening very quickly due to the drug’s potency and the widespread presence of fentanyl in counterfeit pills. Because even small amounts can cause overdose, professional treatment, medical detox, therapy, and ongoing recovery support are often essential for long-term recovery and overdose prevention.”

How Potent Is Fentanyl Compared to Other Opioids?

Fentanyl is dangerous for many reasons, but its potency is one of the biggest. Fentanyl is far stronger than many opioids people may be more familiar with, which is one reason fentanyl abuse can become life-threatening so quickly.

In general, fentanyl is estimated to be:

  • About 50 times stronger than heroin
  • About 100 times stronger than morphine
  • Much more potent than many prescription opioids when taken outside a medical setting

When used properly in a hospital or under a physician’s care, fentanyl can serve an appropriate medical purpose. The danger rises sharply when fentanyl is made illegally, mixed into other substances, or taken without knowing the dose. With illicit fentanyl, even a tiny miscalculation can make the difference between getting high and experiencing a fatal overdose.

This is also why comparing fentanyl to other opioids matters. Someone who has used heroin, oxycodone, or another opioid may assume they understand their tolerance, but fentanyl can overpower the body much faster. That level of potency makes fentanyl abuse especially risky for people who are using alone, mixing substances, or taking counterfeit pills.

What Are the Stats Around Fentanyl Usage and Overdose?

On the Fentanyl DrugFacts page on its official website, the National Institute on Drug Abuse reports that “Synthetic opioids, including fentanyl, are now the most common drugs involved in drug overdose deaths in the United States.”

We also know that both usage of and deaths related to illicitly manufactured fentanyl remain a serious public health concern. 

Although overdose deaths involving synthetic opioids have recently declined, fentanyl remains one of the most dangerous drugs driving the overdose crisis in the United States. 

According to the CDC, 47,735 overdose deaths in 2024 involved synthetic opioids other than methadone, a category that includes fentanyl and fentanyl analogs. The risk is not limited to adults. Among adolescents ages 10 to 19, CDC research found that 84% of overdose deaths studied involved illicitly manufactured fentanyls, showing how deeply fentanyl has affected young people as well as adults.

Fentanyl overdose risk is not limited to people with a long history of opioid use. This danger is especially high when medications are obtained or used outside of a medical setting. A person may think they are taking oxycodone, hydrocodone, Xanax, or another prescription medication, but if the pill is counterfeit, it may contain fentanyl without their knowledge.

What Does Fentanyl Do to the Body?

As with other opioids like heroin and morphine, fentanyl attaches to receptors in the brain responsible for delivering sensations of pain and pleasure. This can cause a wide range of experiences for the user, including extreme happiness, reduction in pain, drowsiness, nausea, confusion, constipation, sedation, problems breathing, unconsciousness, and death.

The most dangerous effect of fentanyl is slowed or stopped breathing. When breathing becomes too shallow, the brain and body do not get enough oxygen, which can quickly lead to brain injury, coma, or a fatal overdose. Because fentanyl is so potent, this can happen faster than many people expect.

Common signs of a fentanyl overdose may include:

  • Slow, weak, or stopped breathing
  • Blue or gray lips and fingernails
  • Pinpoint pupils
  • Extreme sleepiness or inability to wake up
  • Cold or clammy skin
  • Gurgling, choking, or snoring-like sounds
  • Limp body

If someone may be overdosing, call 911 immediately and use naloxone if it is available. Naloxone can reverse an opioid overdose, but emergency care is still necessary.

How Does Fentanyl Use Lead to Addiction?

Fentanyl is an extremely powerful drug, and repeated use can quickly increase the risk of addiction. Like many other substances, fentanyl use can lead to tolerance, meaning the brain and body become used to the drug over time. When this happens, the same amount may no longer produce the same effect. A person may then feel driven to use more fentanyl or use it more often, which can deepen dependence and make the cycle of addiction harder to break

Over time, fentanyl can change the brain’s reward system. A person may begin using it to feel good, but later feel like they need it just to avoid withdrawal symptoms. This cycle can make fentanyl addiction feel overwhelming and difficult to stop without professional support.

Signs of fentanyl addiction may include:

  • Using fentanyl or other opioids more often than intended
  • Feeling unable to cut back or stop
  • Strong cravings
  • Withdrawal symptoms when not using
  • Spending significant time finding, using, or recovering from fentanyl
  • Continuing to use despite health, family, work, school, or legal consequences
  • Using alone or taking bigger risks to avoid withdrawal

Why is Fentanyl So Dangerous?

Fentanyl is dangerous for several reasons, but the biggest concern is how unpredictable it can be when it is made or sold illegally. Its strength, the risk of hidden exposure, and the difficulty of knowing the dose all make fentanyl one of the most serious drug threats in the United States.

Fentanyl Is Extremely Potent

One of the main reasons fentanyl is so dangerous is its strength. According to the CDC, fentanyl is up to 50 times stronger than heroin and 100 times stronger than morphine. Because of this, even a very small amount can cause a fatal overdose, especially in someone with little or no opioid tolerance.

A Small Amount Can Be Deadly

The DEA reports that 2 milligrams of fentanyl can be a potentially deadly dose, depending on a person’s size, tolerance, and other factors. This is part of what makes illicit fentanyl so unpredictable. A person may not be able to see, measure, or recognize how much fentanyl is in a pill, powder, or other substance.

To show the scale of the crisis, the DEA reported that its 2025 seizures included more than 47 million fentanyl-laced counterfeit pills and nearly 10,000 pounds of fentanyl powder, which the agency estimated was equal to more than 369 million lethal doses.

Fentanyl Is Often Hidden in Other Drugs

Another major reason fentanyl is so dangerous is that many people do not know they are taking it. Illicitly manufactured fentanyl may be mixed into heroin, cocaine, methamphetamine, and other substances. It may also be pressed into counterfeit pills made to look like prescription medications.

Because fentanyl cannot be seen, smelled, or tasted, a person may believe they are taking one substance while actually taking fentanyl. That hidden exposure is one of the reasons overdose can happen so suddenly.

Counterfeit Pills Can Contain Deadly Amounts

Even when a pill looks like a prescription medication, there is no guarantee it came from a pharmacy or contains what the person thinks it does. DEA testing reported in late 2024 found that 5 out of 10 fentanyl-tested pills contained a potentially deadly dose. This was down from previous years, but it still shows how dangerous counterfeit pills remain.

The Dose Is Unpredictable

With illicit fentanyl, there is no reliable way for someone to know how much they are taking. One pill or powder sample may contain a small amount, while another may contain enough to cause an overdose. That lack of consistency is one of the biggest reasons fentanyl use is so dangerous.

Because fentanyl is so potent, often hidden, and difficult to dose safely outside of medical care, it remains one of the clearest examples of why overdose prevention, education, and professional addiction treatment matter.

Why Counterfeit Pills Make Fentanyl Abuse More Dangerous

One of the most frightening parts of the fentanyl crisis is that many people do not know they are taking fentanyl. Illicit fentanyl is often pressed into pills made to look like prescription medications, including opioids, anxiety medications, or stimulants. A person may believe they are taking a familiar pill, when in reality, the drug may contain a potentially lethal amount of fentanyl.

Counterfeit pills can be especially dangerous because they may look nearly identical to medications someone has seen before. The shape, color, markings, or packaging may seem convincing, but there is no way to confirm what is actually inside without testing. Even pills from the same batch may contain different amounts of fentanyl.

This unpredictability increases overdose risk. Fentanyl abuse is not always intentional in the way people expect; sometimes, a person is exposed to fentanyl while trying to use another substance. That is why education, prevention, and fast access to treatment are so important.

What Do You Do If You Have a Fentanyl Addiction?

Fentanyl addiction is serious, and stopping without support can be difficult and unsafe. The safest next step is to reach out for professional help and follow a structured treatment plan.

Step What to Do Why It Matters
Step 1 Contact a treatment center
  • Get help as soon as possible
  • Lower the risk of continued use
  • Start with professional guidance
Step 2 Begin medically supervised detox
  • Manage withdrawal symptoms safely
  • Receive 24/7 care and support
  • Reduce the risk of relapse during withdrawal
Step 3 Continue into addiction treatment
  • Detox alone is not full treatment
  • Address triggers and cravings
  • Build recovery skills through therapy and peer support
Step 4 Create a long-term recovery plan
  • Learn relapse prevention tools
  • Build healthy routines
  • Stay connected to ongoing support

At Midwest Recovery Centers, clients can begin with residential detox and continue into a multi-phase treatment program that supports long-term recovery from fentanyl addiction.

Fentanyl Addiction Treatment at Midwest Recovery Centers

Fentanyl addiction can affect every part of a person’s life, from physical health and mental well-being to relationships, work, and long-term stability. At Midwest Recovery Centers, treatment is built to support people at different points in recovery, whether they need a highly structured setting, ongoing support, or a more flexible outpatient option.

A Recovery Path That Starts With Structure

For clients seeking substance use treatment, care begins with a strong clinical foundation. Midwest Recovery Centers uses a phased model that starts with medical detox and residential treatment during the first 30 days. This early stage gives clients a safe place to move through withdrawal, stabilize, and begin the recovery process with medical and therapeutic support.

After that initial period, clients may continue through:

  • Phase 1, which typically lasts around 60 days and includes housing
  • Phase 2, which may continue for up to 9 months, also includes housing

This approach allows clients to stay in a recovery-focused environment while continuing treatment, building healthy routines, and working toward greater independence over time.

Substance Use Support for More Than Fentanyl

While this page focuses on fentanyl addiction treatment, Midwest Recovery Centers also provides care for people facing other substance use concerns. Treatment may support individuals struggling with:

  • Alcohol use
  • Heroin use
  • Methamphetamine use
  • Cocaine use
  • Marijuana use
  • Prescription drug misuse
  • Other substance use disorders

Medication-assisted treatment is available during detox as part of the withdrawal and stabilization process.

Outpatient Options Through Community IOP

Not everyone is in a position to commit to a longer-term program with housing. For those who need a more flexible level of care, Midwest Recovery Centers also offers: 

These outpatient programs may include supportive services such as:

  • Medication management
  • Psychiatric evaluations
  • TMS (Transcranial Magnetic Stimulation)
  • Long-acting injectables (LAI)
  • Genetic testing
  • Telemedicine support

For some clients, Community IOP can be a practical way to receive consistent care while maintaining work, school, or family responsibilities.

Mental Health and Co-Occurring Disorder Care

Fentanyl addiction often overlaps with mental health symptoms, which is why treatment should not look at substance use in isolation. Midwest Recovery Centers provides care for mental health concerns, including a 45-day residential mental health program for primary mental health disorders.

Outpatient mental health services are also available and do not always need to follow residential treatment.

For clients dealing with both addiction and mental health symptoms, Midwest Recovery Centers offers co-occurring disorder treatment that addresses both at the same time. This integrated approach can help clients better understand the connection between their symptoms, triggers, and recovery needs.

Support for Families During the Recovery Process

Addiction affects more than the person receiving treatment. Families often need support, education, and guidance as they learn how to respond in healthier ways.

Midwest Recovery Centers offers virtual family programming for substance use disorders every Thursday from 6:30–8:00 PM CST in a four-part monthly rotation:

  • 1st Thursday: Addiction education, causes, family dynamics, and what to expect at MRC
  • 2nd Thursday: Enabling, healthy support, grief, and codependency
  • 3rd Thursday: Boundaries before, during, and after treatment
  • 4th Thursday: Family recovery, self-care, detaching with love, and changing family roles

There is also a Virtual Family Program for Mental Health held on the 3rd Thursday of each month at 8:00 PM CST, giving families another space to learn, connect, and feel supported.

In addition, Midwest Recovery Centers hosts an in-person session called “Supporting Their Next Steps: An Aftercare Info Session for Families” on the 1st Wednesday of each month at 7:00 PM at the Main Outpatient Campus:

13340 Holmes Rd, Kansas City, MO 64145

Continued Support After Treatment

Recovery does not end when a program does. Aftercare support helps clients move from structured treatment into everyday life with more confidence and stability.

This may include:

  • Counselor check-ins
  • Ongoing therapy
  • Relapse prevention planning
  • Connection to community-based support

That continued support can play an important role during the first year after treatment and beyond, especially for people working to rebuild daily life after fentanyl addiction.

Treatment Outcomes at Midwest Recovery Centers

At Midwest Recovery Centers, treatment progress is not based on guesswork. We use regular check-ins and outcome-tracking tools to monitor the areas that affect recovery most, including cravings, sleep, mood, substance-use patterns, and risk of return to use. Tools like the Brief Addiction Monitor, or BAM, help our team see how clients are doing over time and make adjustments when more support is needed.

We also monitor mental health symptoms throughout care, so improvement does not stay vague or hard to measure. By tracking changes in depression, anxiety, PTSD symptoms, cravings, sleep, and recovery satisfaction, our clinical team can better understand what is working and where each client may need additional support.

Substance Use Outcomes

In Midwest Recovery Centers’ 2024–2025 outcomes data, alcohol use, drug use, marijuana use, sedative use, and overall substance use each showed a 100% reduction while clients were in care. During that same period:

  • Risk of use decreased by 64%
  • Cravings dropped by about 55%
  • Sleep problems improved by as much as 81%
  • Mood concerns decreased by 75%
  • Satisfaction with recovery improved by about 80%
  • Spirituality increased by about 26%

These outcomes matter because fentanyl addiction and fentanyl abuse often affect more than substance use alone. Sleep, mood, cravings, stress, and emotional stability can all influence whether someone feels steady enough to continue recovery.

Mental Health Outcomes

For clients in Midwest Recovery Centers’ mental health programs, outcome tracking also showed meaningful improvement. PHQ-9 results showed depression symptoms decreasing by 87%, while GAD-7 results showed anxiety symptoms improving by as much as 78%. PTSD scores also trended downward substantially across follow-ups using the PCL-5.

These numbers reflect the importance of treating mental health and addiction together when needed. For many people, fentanyl abuse, opioid addiction, anxiety, depression, trauma, and emotional distress are closely connected. Addressing those concerns in the same treatment setting can give clients a stronger foundation for long-term recovery.

Because progress is personal, these outcomes do not promise that every client will experience the exact same results. They do show what is possible when care is structured, consistent, and tailored to the patient’s specific needs.
