What You Should Know About Carfentanil

Carfentanil is a synthetic opioid and fentanyl analog, meaning it’s similar to fentanyl but more potent and cheaper. It’s believed to be 10,000 times more potent than morphine, about 100 times more potent than fentanyl, and 50 times more potent than heroin, all of which are highly addictive opioids, as well. In recent years, carfentanil has surfaced in more and more communities. It’s a drug that’s commonly sold as heroin or mixed into other drugs to intensify their side effects. As with other opioids, carfentanil can be not only addictive but also deadly. Our drug rehab is sharing what you should know about carfentanil.

What Is Carfentanil Used For?

As a Schedule II drug, carfentanil has an accepted medical use as well as a high potential for abuse that can lead to physical dependence or addiction. In the medical field, carfentanil is used as a tranquilizer for elephants and other large mammals. Carfentanil works as an agonist on mu-opioid receptors in the brain and spinal cord. This means that it acts like other opioids by attaching itself to these receptors to alleviate pain and produce sedation. The fact that it’s used as a tranquilizer for large animals should give you an idea of how deadly it is for people.

Carfentanil is also sold and used illegally on the streets. Those with opioid addictions often turn to this drug for a more intense high. Additionally, carfentanil is a common cutting agent in street drugs like heroin and cocaine because they’re all white, powdery substances. Cutting agents are substances that are added to drugs to make them more powerful or to make them weigh more. This allows drug dealers to make more profit with fewer products. However, this also increases the likelihood of overdose-related death. Individuals who struggle with carfentanil abuse and do not receive care, such as a medically monitored detox, are more likely to stay addicted and suffer consequences like an overdose.

Carfentanil Side Effects

Carfentanil is also part of a combination called “gray death,” which is a mixture of heroin, fentanyl, carfentanil, and other opioids. Additionally, because carfentanil is a common cutting agent, many opioid and cocaine users often take this drug unknowingly. In doing so, they run the risk of injury or developing a dependence on it.

If someone takes carfentanil and doesn’t die or overdose, any symptoms or side effects they experience will be similar to those produced by other opioids. People who abuse this drug may experience calmness, tranquility, nausea, vomiting, and drowsiness. Other common side effects of carfentanil include:

  • Sedation
  • Runny nose
  • Insomnia or difficulty sleeping
  • Excessive sweating
  • Muscle aches
  • Depression
  • Difficulty concentrating
  • Reduced motor movement
  • Loss of coordination

Even people who do not directly use carfentanil, but use other substances that may contain it, are at risk of addiction and overdose. If you’re addicted to heroin or cocaine and do not receive inpatient drug treatment, then your risk of experiencing these repercussions is increased.

Long-Term Effects of Carfentanil Use

Like other opioids, long-term use of carfentanil can cause chronic respiratory problems due to the drug's sedative effects on the central nervous system. Users often experience mental health issues such as depression, anxiety, and cognitive impairment, making it difficult to lead a functional life.

Additionally, carfentanil use often leads to physical dependency, meaning the body becomes reliant on the drug to function normally. This can result in severe withdrawal symptoms if the user attempts to stop. Long-term addiction to carfentanil not only impacts physical health but also destroys relationships, careers, and other aspects of personal life, leaving users isolated and vulnerable.

Signs and Symptoms of Carfentanil Abuse

Because opioids depress or sedate the central nervous system, basic functions like breathing and heart rate are slowed significantly. Usually, the deadliest symptom of an opioid overdose is respiratory depression, in which the person has difficulty breathing and is unable to get enough oxygen to their brain. Heart failure and other side effects may also occur as a result of opioid use, including addiction.

Some common carfentanil overdose symptoms include:

  • Pinpoint pupils
  • Unconsciousness
  • Respiratory depression
  • Unresponsiveness
  • Limp body
  • Awake, but unable to speak
  • Pale or clammy skin
  • Blue skin, lips, and fingernails
  • Slow or shallow breathing
  • Irregular or stopped breathing
  • Choking or gurgling sounds (also referred to as the “death rattle”)
  • Nausea and/or vomiting

How Much Of Carfentanil Is Fatal?

The most common side effect of carfentanil is death. Even the smallest dose of carfentanil can be fatal, but it’s difficult to determine how much of this drug is present in heroin or cocaine, if at all. In humans, 1 microgram of carfentanil is enough to make someone high, and the fatal carfentanil dosage is 20 micrograms, which is less than a grain of salt.

You can also overdose on carfentanil if you take anything less than 20 micrograms (20 being the fatal dose). A drug overdose is when the body is overwhelmed by a toxic substance, during which a person may exhibit certain behavioral and physical symptoms.

Treatment Options for Carfentanil Addiction

Because of its potency and high risk of fatal overdose, treating carfentanil addiction requires a comprehensive approach. At Banyan Treatment Center facilities, we take a well-rounded approach to opioid addiction treatment. The first step is medical detox, where individuals can safely withdraw from the drug under the supervision of medical professionals. This reduces the risks associated with withdrawal and helps manage severe symptoms.

Following detox, individuals can enter inpatient or outpatient rehabilitation programs, depending on their needs. Inpatient rehab offers a controlled environment where patients receive around-the-clock care, while outpatient programs allow more flexibility for those with external responsibilities. Additionally, therapy and other programs are crucial for addressing the psychological aspects of addiction. These help individuals develop healthier coping strategies and reduce the likelihood of relapse.

At Banyan Treatment Center, we take a comprehensive approach to opioid addiction treatment, combining medical care, therapy, and ongoing support to give individuals the best chance at long-term recovery.
